Description In the last decade, the Earth's temperature rose roughly a third of a degree fahrenheit. Since 1880, it's risen about one and a half degrees. You might say the Earth's running a fever. And scientists predict it's going to get much worse. Already, we can tally the signs. Global sea level rose by over an inch during the decade, almost twice as fast as the average during the twentieth century. Arctic summer sea ice declined by over 300,000 square miles – enough ice to cover the states of Texas and Kentucky. The vast majority of climate scientists say evidence for human-caused warming is clear. But less understood is exactly how this warming will change the complex interactions between our planet's land, water, sky, and the living the organisms that inhabit our world.

Description Armadillo Aerospace successfully met the Level 2 requirements for the Centennial Challenges - Lunar Lander Challenge and qualified to win a $1 million dollar first place prize. The flights were conducted Sept. 12 at the Armadillo Aerospace test facility in Caddo Mills, Texas. To qualify for the Level 2 prize, Armadillo Aerospace's rocket vehicle took off from one concrete pad, ascended horizontally, then landed on a second pad that featured boulders and craters to simulate the lunar surface. After refueling at that pad, the vehicle then repeated the flight back and landed at the original pad. The vehicle completed the round trip, including fueling and refueling operations, in one hour and 47 minutes. That was well within the two and half hour time limit for the challenge. Armadillo Aerospace also met the requirement to remain aloft under rocket power for three minutes during each of the flights. In this image, technicians Neil Milburn, Russ Blink and Mike Vinther are shown on the launch pad performing a vehicle inspection. Image Credit: NASA/James Blair

Title Mysterious Blob Galaxies Revealed
Description This image composite shows a giant galactic blob (red, left) and the three merging galaxies NASA's Spitzer Space Telescope discovered within it (yellow, right). Blobs are intensely glowing clouds of hot hydrogen gas that envelop faraway galaxies. They are about 10 times as large as the galaxies they surround. Visible-light images like the one shown here (left), reveal the vast extent of blobs, but don't provide much information about their host galaxies. Using its heat-seeking infrared eyes, Spitzer was able to see the dusty galaxies tucked inside one well-known blob located 11 billion light-years away. The findings reveal three monstrously bright galaxies, trillions of times brighter than the Sun, in the process of merging together (right). Spitzer also observed three other blobs located in the same cosmic neighborhood, all of which were found to be glaringly bright. One of these blobs is also known to be a galactic merger, only between two galaxies instead of three. It remains to be seen whether the final two blobs studied also contain mergers. The Spitzer data were acquired by its multiband imaging photometer. The visible-light image was taken by the Blanco Telescope at the Cerro Tololo Inter-American Observatory, Chile.

Perseus' Stellar Neighbors
Title Perseus' Stellar Neighbors
Description Baby stars are forming near the eastern rim of the cosmic cloud Perseus, in this infrared image from NASA's Spitzer Space Telescope. The baby stars are approximately three million years old and are shown as reddish-pink dots to the right of the image. The pinkish color indicates that these infant stars are still shrouded by the cosmic dust and gas that collapsed to form them. These stars are part of the IC348 star cluster, which consists of over 300 known member stars. The Perseus Nebula can be seen as the large green cloud at the center of the image. Wisps of green are organic molecules called Polycyclic Aromatic Hydrocarbons (PAHs) that have been illuminated by the nearby star formation. Meanwhile, wisps of orange-red are dust particles warmed by the newly forming stars. The Perseus Nebula is located about 1,043 light-years away in the Perseus constellation. The image is a three channel false color composite, where emission at 4.5 microns is blue, emission at 8.0 microns is green, and 24-micron emission is red.
Seeing Stars in Serpens
Title Seeing Stars in Serpens
Description Infant stars are glowing gloriously in this infrared image of the Serpens star-forming region, captured by NASA's Spitzer Space Telescope. The reddish-pink dots are baby stars deeply embedded in the cosmic cloud of gas and dust that collapsed to create it. A dusty disk of cosmic debris, or "protoplanetary disk," that may eventually form planets, surrounds the infant stars. Wisps of green throughout the image indicate the presence of carbon rich molecules called, Polycyclic Aromatic Hydrocarbons (PAHs). On Earth, PAHs can be found on charred barbecue grills and in automobile exhaust. Blue specks sprinkled throughout the image are background stars in our Milky Way Galaxy. The Serpens star-forming region is located approximately 848 light-years away in the Serpens constellation. The image is a three-channel false-color composite, where emission at 4.5 microns is blue, emission at 8.0 microns is green, and 24 micron emission is red.
Bubbly Little Star
Title Bubbly Little Star
Description In this processed Spitzer Space Telescope image, baby star HH 46/47 can be seen blowing two massive "bubbles." The star is 1,140 light-years away from Earth. The infant star can be seen as a white spot toward the center of the Spitzer image. The two bubbles are shown as hollow elliptical shells of bluish-green material extending from the star. Wisps of green in the image reveal warm molecular hydrogen gas, while the bluish tints are formed by starlight scattered by surrounding dust. These bubbles formed when powerful jets of gas, traveling at 200 to 300 kilometers per second, or about 120 to 190 miles per second, smashed into the cosmic cloud of gas and dust that surrounds HH 46/47. The red specks at the end of each bubble show the presence of hot sulfur and iron gas where the star's narrow jets are currently crashing head-on into the cosmic cloud's gas and dust material. Whenever astronomers observe a star, or snap a stellar portrait, through the lens of any telescope, they know that what they are seeing is slightly blurred. To clear up the blurring in Spitzer images, astronomers at the Jet Propulsion Laboratory developed an image processing technique for Spitzer called Hi-Res deconvolution. This process reduces blurring and makes the image sharper and cleaner, enabling astronomers to see the emissions around forming stars in greater detail. When scientists applied this image processing technique to the Spitzer image of HH 46/47, they were able to see winds from the star and jets of gas that are carving the celestial bubbles. This infrared image is a three-color composite, with data at 3.6 microns represented in blue, 4.5 and 5.8 microns shown in green, and 24 microns represented as red.
Stellar Families
Title Stellar Families
Description Human families may be bonded by blood, but stellar families are united by gravity. A family of stars, or star cluster, can contain hundreds or thousands of members. In this image, NASA's Spitzer Space Telescope spots the Serpens South star cluster, which consists of a relatively dense group of 50 young stars -- 35 of which are protostars, or stellar infants, that are just beginning to form. Stellar members of Serpens South star cluster can be seen as the green, yellow, and orange tinted specks sitting atop the black dust lane running down the center of the image. Like raindrops, stars form when thick patches of cosmic clouds condense. Tints of green in the image represent hot hydrogen gas excited when high-speed jets of gas ejected by infant stars collide with the cool gas in the surrounding cloud. Wisps of red in the background are organic molecules called polycyclic aromatic hydrocarbons (PAHs), which are being excited by stellar radiation from a neighboring star-forming region located to the east of this image, called W40. On Earth PAHs are found on charred barbeque grills and in the sooty automobile exhaust. This Spitzer picture is composed of three images taken with the telescope's Infrared Array Camera (IRAC) at 3.6 (blue), 4.5 (green), and 5.8 (red) microns.
HH46/47
Title HH46/47
Description This image from NASA's Spitzer Space Telescope transforms a dark cloud into a silky translucent veil, revealing the molecular outflow from an otherwise hidden newborn star. Using near-infrared light, Spitzer pierces through the dark cloud to detect the embedded outflow in an object called HH 46/47. Herbig-Haro (HH) objects are bright, nebulous regions of gas and dust that are usually buried within dark clouds. They are formed when supersonic gas ejected from a forming protostar, or embryonic star, interacts with the surrounding interstellar medium. These young stars are often detected only in the infrared. The Spitzer image was obtained with the infrared array camera. Emission at 3.6 microns is shown as blue, emission from 4.5 and 5.8 microns has been combined as green, and 8.0 micron emission is depicted as red. HH 46/47 is a striking example of a low mass protostar ejecting a jet and creating a bipolar, or two-sided, outflow. The central protostar lies inside a dark cloud (known as a 'Bok globule') which is illuminated by the nearby Gum Nebula. Located at a distance of 1140 light-years and found in the constellation Vela, the protostar is hidden from view in the visible-light image (inset). With Spitzer, the star and its dazzling jets of molecular gas appear with clarity. The 8-micron channel of the infrared array camera is sensitive to emission from polycyclic aromatic hydrocarbons. These organic molecules, comprised of carbon and hydrogen, are excited by the surrounding radiation field and become luminescent, accounting for the reddish cloud. Note that the boundary layer of the 8-micron emission corresponds to the lower right edge of the dark cloud in the visible-light picture. Outflows are fascinating objects, since they characterize one of the most energetic phases of the formation of low-mass stars (like our Sun). The jets arising from these protostars can reach sizes of trillions of miles and velocities of hundreds of thousands miles per hour. Outflows are clear evidence of the presence of a process that creates supersonic beams of gas. This mechanism is tightly bound to the presence of circumstellar discs which surround the young stars. Such discs are likely to contain the materials from which planetary systems form. Our Sun probably underwent a similar process some 4.5 billion years ago. Hence the interest in understanding how quickly and efficiently this mass accretion and loss process takes place in protostars.

The Starless Core That Isn't
Title The Starless Core That Isn't
Description The "Cores to Disks" Spitzer Legacy team is using the two infrared cameras on NASA's Spitzer Space Telescope to search dense regions of interstellar molecular clouds (known as "cores") for evidence of star formation. Part of the study targeted a group of objects with no known stars to study the properties of such regions before any stars have formed. The first of these "starless cores" to be examined held a surprise: a source of infrared light appeared where none was expected. The core is known as L1014, the 1,014th object in a list of dark, dusty "clouds" compiled by astronomer Beverly Lynds over 40 years ago. These have proved to be homes to a rich variety of molecules and are the birthplaces of stars and planets. The Spitzer image is a 3.6 micron (blue), 8.0 micron (green) and 24.0 micron (red) composite image. The light seen in the infrared image originates from very different sources. The bright yellow object at the center of the image is the object detected in the "starless core". The red ring surrounding the object is an artifact of the reduced spatial resolution of the telescope at 24 microns. At 3.6 microns the light comes mainly from the object at the heart of the core. At longer wavelengths, the light from the object becomes stronger, a signature that it is not a background star. Also in the longer wavelengths (8.0 to 24.0 microns), astronomers saw the glow from interstellar dust, glowing green to red in the Spitzer composite image. This dust consists mainly of a variety of carbon-based organic molecules known collectively as polycyclic aromatic hydrocarbons. The red color traces a cooler dust component. No previous observations showed any hint of a source in L1014. For example, the visible light image is from the Digital Sky Survey and is a B-, R-, and I-band composite image (wavelengths ranging from 0.4 to 0.7 microns). The dark cloud in the center of the image is the core, completely opaque in the visible due to obscuration by dust. The L1014 core lies in the direction of Cygnus. It is thought to be about 600 light years away, but the distance is somewhat uncertain. The results from this study are published by C. Young and the "Cores to Disks" team in the Astrophysical Journal.

title Two Moons Passing in the Night
date 08.26.2005
description Taking advantage of extra solar energy collected during the day, NASA's Mars Exploration Rover Spirit settled in for an evening of stargazing, photographing the two moons of Mars as they crossed the night sky. "It is incredibly cool to be running an observatory on another planet," said planetary scientist Jim Bell of Cornell University, Ithaca, N.Y., lead scientist for the panoramic cameras on Spirit and Opportunity. In this animation, both martian moons, Deimos on the left and Phobos on the right, travel across the night sky in front of the constellation Sagittarius. Part of Sagittarius resembles an upside-down teapot. Phobos is the brighter object on the right, Deimos is on the left. Spirit acquired these enhanced-brightness images with the panoramic camera on the night of sol 585 (Aug. 26, 2005). Scientists will use images of the two moons to better map their orbital positions, learn more about their composition, and monitor the presence of nighttime clouds or haze. Spirit took the six images that make up this animation using the camera's broadband filter, which was designed specifically for acquiring images under low-light conditions. *Image credit:* NASA/JPL/Cornell/ Texas A&M

description This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd Martian day, or sol, of its mission. The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth. The contrast in the panoramic camera image was increased two times to make Earth easier to see.The inset shows a combination of four panoramic camera images zoomed in on Earth. The arrow points to Earth. Earth was too faint to be detected in images taken with the panoramic camera's color filters. *Image Credit*: NASA/JPL/Cornell/Texas A&M

date 07.01.1979
description An unofficial sustained American aviation altitude record for women was set July 1, 1979, by astronaut candidate Kathryn D. Sullivan in a NASA WB-57F reconnaissance aircraft. The record altitude of 63,300 feet was reached during a four-hour flight. Sullivan, in a high altitude pressure suit, operated color infrared cameras and multispectral scanning equipment as the WB-57F spent one and one-half hours of the Big Bend area of West Texas. Piloting the aircraft was Jim Korkowski, one of the NASA Airborne Instrumentation Research Program Pilots. The flight was out of Ellington AFB near Houston. Sullivan, who has a doctorate in geology, was selected in 1978 as one of 35 astronaut candidates training for the Shuttle program. She trained to be a mission specialist and flights in the WB-57F were training in preparation for her assignments on the Shuttle. Sullivan later served as a mission specialist on STS-41G, STS-31, and STS-45. *Image Credit*: NASA
Two Moons Meet over Jupiter
title Two Moons Meet over Jupiter
date 03.02.2007
description This beautiful image of the crescents of volcanic Io and more sedate Europa was snapped by New Horizons' color Multispectral Visual Imaging Camera (MVIC) at 10:34 UT on March 2, 2007, about two days after New Horizons made its closest approach to Jupiter. The picture was one of a handful of the Jupiter system that New Horizons took primarily for their artistic, rather than scientific value. This particular scene was suggested by space enthusiast Richard Hendricks of Austin, Texas, in response to an Internet request by New Horizons scientists for evocative, artistic imaging opportunities at Jupiter. This image was taken from a range of 4.6 million kilometers (2.8 million miles) from Io and 3.8 million kilometers (2.4 million miles) from Europa. Although the moons appear close in this view, a gulf of 790,000 kilometers (490,000 miles) separates them. The night side of Io is illuminated here by light reflected from Jupiter, which is out of the frame to the right. Europa's night side is completely dark, in contrast to Io, because that side of Europa faces away from Jupiter. Here, Io steals the show with its beautiful display of volcanic activity. Three volcanic plumes are visible. Most conspicuous is the enormous 300-kilometer (190-mile) -high plume from the Tvashtar volcano at the 11 o'clock position on Io's disk. Two much smaller plumes are barely visible: one from the volcano Prometheus, at the 9 o'clock position on the edge of Io's disk, and one from the volcano Amirani, seen between Prometheus and Tvashtar along Io's terminator (the line dividing day and night). The plumes appear blue because of the scattering of light by tiny dust particles ejected by the volcanoes, similar to the blue appearance of smoke. In addition, the contrasting red glow of hot lava can be seen at the source of the Tvashtar plume. The images are centered at 1 degree north, 60 degrees west on Io, and 0 degrees north, 149 degrees west on Europa. The color in this image was generated using individual MVIC images at wavelengths of 480, 620 and 850 nanometers. The human eye is sensitive to slightly shorter wavelengths, from 400 to 700 nanometers, and thus would see the scene slightly differently. For instance, while the eye would notice the difference between the yellow and reddish brown colors of Io's surface and the paler color of Europa, the two worlds appear very similar in color to MVIC's longer-wavelength vision. The night side of Io appears greenish compared to the day side, because methane in Jupiter's atmosphere absorbs 850-nanometer light and makes Jupiter-light green to MVIC's "eyes." MVIC is a component of the Ralph imaging instrument. Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute
Charon Discovery Image
title Charon Discovery Image
date 06.22.1978
description On 22 June 1978, an astronomer at the U.S. Naval Observatory in Washington, D.C. was making routine measurements of photographic plates taken with the 1.55-meter (61-inch) Kaj Strand Astrometric Reflector at the USNO Flagstaff Station in Arizona. The purpose of these images was to refine the orbit of the far-flung planet Pluto to help compute a better ephemeris for this distant object. Astronomer James W. Christy had noticed that a number of the images of Pluto appeared elongated, but images of background stars on the same plate did not. Other plates showed the planet as a tiny, round dot. Christy examined a number of Pluto images from the USNO archives, and he noticed the elongations again. Furthermore, the elongations appeared to change position with respect to the stars over time. After eliminating the possibility that the elongations were produced by plate defects and background stars, the only plausible explanation was that they were caused by a previously unknown moon orbiting Pluto at a distance of about 19,600 kilometers (12,100 miles) with a period of just over six days. On 7 July 1978, the discovery was formally announced to the astronomical community and the world by the IAU Central Bureau for Astronomical Telegrams via IAU Circular 3241. The discovery received the provisional designation "1978 P 1", Christy proposed the name "Charon", after the mythological ferryman who carried souls across the river Acheron, one of the five mythical rivers that surrounded Pluto's underworld. Over the course of the next several years, another USNO astronomer, the late Robert S. Harrington, calculated that Pluto and its newly-found moon would undergo a series of mutual eclipses and occultations, beginning in early 1985. On 17 February 1985 the first successful observation of one of these transits was made at with the 0.9-meter (36-inch) reflector at the University of Texas McDonald Observatory, within 40 minutes of Harrington's predicted time. The IAU Circular announcing these confirming observations was issued on 22 February 1985. With this confirmation, the new moon was officially named Charon. Pluto was discovered at Lowell Observatory in 1930 by the late Clyde W. Tombaugh, an amateur astronomer from Kansas who was hired by the Observatory specifically to photograph the sky with a special camera and search for the planet predicted by the Observatory's founder, Percival Lowell. Lowell had deduced the existence of a "Planet X" by studying small anomalies in the orbits of Uranus and Neptune. As it turned out, Pluto's discovery was almost entirely serendipitous, Pluto's tiny mass was far too small to account for the anomalies, which were resolved when Voyager 2 determined more precise masses for Uranus and Neptune. The discovery of Charon has led to a much better understanding of just how tiny Pluto is. Its diameter is about 2274 km (1413 miles), and its mass is 0.25% of the mass of the Earth. Charon has a diameter of about 1172 kilometers (728, miles) and a mass of about 22% that of Pluto. The two worlds circle their common center of mass with a period of 6.387 days and are locked in a "super-synchronous" rotation: observers on Pluto's surface would always see Charon in the same part of the sky relative to their local horizon. Normally Pluto is considered the most distant world in the solar system, but during the period from January 1979 until February 1999 it was actually closer to the Sun than Neptune. It has the most eccentric and inclinced orbit of any of the major planets. This orbit won't bring Pluto back to its discovery position until the year 2178! *Image Credit*: U.S. Naval Observatory
Meteorite Hunters
title Meteorite Hunters
description When a meteorite is found, the ANSMET (Antarctic Search for Meteorites) team records its location, size, color, amount of fusion crust, probable type, and anything else that might be important. Some of their tools are similar to those used by the Apollo astronauts to collect samples, and some are the latest high-tech (like Global Positioning Satellite navigation). The team takes great care not to contaminate the meteorites. Meteorites are handled only with stainless steel instruments, and are immediately sealed in sterile plastic or aluminum foil packages. Meteorites collected by the ANSMET team in Antarctica are packed in dry ice to mimic conditions in the field and shipped to the Antarctic Meteorite Laboratory at NASA's Johnson Space Center in Houston, Texas. *Image Credit*: NASA Johnson Space Center

An Eruption on Io
title An Eruption on Io
date 02.26.2007
description The first images returned to Earth by New Horizons during its close encounter with Jupiter feature the Galilean moon Io, snapped with the Long Range Reconnaissance Imager (LORRI) at 0840 UTC on February 26, while the moon was 2.5 million miles (4 million kilometers) from the spacecraft. Io is intensely heated by its tidal interaction with Jupiter and is thus extremely volcanically active. That activity is evident in these images, which reveal an enormous dust plume, more than 150 miles high, erupting from the volcano Tvashtar. The plume appears as an umbrella-shaped feature of the edge of Io's disk in the 11 o'clock position in the right image, which is a long-exposure (20-millisecond) frame designed specifically to look for plumes like this. The bright spots at 2 o'clock are high mountains catching the setting sun, beyond them the night side of Io can be seen, faintly illuminated by light reflected from Jupiter itself. The left image is a shorter exposure -- 3 milliseconds -- designed to look at surface features. In this frame, the Tvashtar volcano shows as a dark spot, also at 11 o'clock, surrounded by a large dark ring, where an area larger than Texas has been covered by fallout from the giant eruption. This is the clearest view yet of a plume from Tvashtar, one of Io's most active volcanoes. Ground-based telescopes and the Galileo Jupiter orbiter first spotted volcanic heat radiation from Tvashtar in November 1999, and the Cassini spacecraft saw a large plume when it flew past Jupiter in December 2000. The Keck telescope in Hawaii picked up renewed heat radiation from Tvashtar in spring 2006, and just two weeks ago the Hubble Space Telescope saw the Tvashtar plume in ultraviolet images designed to support the New Horizons flyby. Most of those images will be stored onboard the spacecraft for downlink to Earth in March and April.

Meteorite Processing
title Meteorite Processing
description After meteorites are found in Antarctica, they are carried to the Antarctic Meteorite Laboratory at NASA's Johnson Space Center in Houston, Texas. There, the meteorites are cataloged, examined, classified, and stored. This slide shows technicians working with meteorites in a sterile cabinet filled with dry nitrogen gas. The dry gas keeps the meteorites relatively free of contamination and keeps them from rusting. The technician on the left is examining a meteorite through a microscope, and the technician on the right is breaking a meteorite to expose its interior. The technicians put their hands into the black rubber gloves on the cabinets, which allows them to work without getting the meteorites dirty or exposing them to air. *Image Credit*: NASA Johnson Space Center

Title Bessie Coleman, First African American Pilot
Full Description Born on January 26, 1892 in Atlanta, Texas to a family of sharecroppers, Bessie Coleman grew up in poverty. Her father abandoned the family when she was nine, and her elder brothers soon left as well, leaving her mother with the four youngest of her thirteen children. While taking care of her younger sisters, Bessie completed all eight available years of primary education, excelling in math. She enrolled at the Colored Agricultural and Normal University in Langston, Oklahoma in 1910, but lack of funds forced her to leave after only one term. Five years later, she left the South and moved to Chicago to join two of her brothers, Walter and John, where she worked as a beautician for several years. An avid reader, she learned about World War I pilots in the newspaper and became intrigued by the prospect of flying. As a black woman, she had no chance of acceptance at any American pilot school, so she moved to France in 1919 and enrolled at the Ecole d'Aviation des Freres Caudon at Le Crotoy. After returning briefly to the United States, she spent one more term in France practicing more advanced flying before finally settling back in her birth country. She did exhibition flying and gave lectures across the country from 1922 to 1926. While flying, she refused to perform unless the audiences were desegregated. She was test flying a new plane on April 30, 1926 when it malfunctioned, killing both her and the mechanic who was piloting it. Her career as the world's first African American pilot inspired many who followed.

Cometary Knots Around A Dyin …
Title Cometary Knots Around A Dying Star
Full Description These gigantic, tadpole-shaped objects are probably the result of a dying star's last gasps. Dubbed "cometary knots" because their glowing heads and gossamer tails resemble comets, the gaseous objects probably were formed during a star's final stages of life. Hubble astronomer C. Robert O'Dell and graduate student Kerry P. Handron of Rice University in Houston, Texas discovered thousands of these knots with the Hubble Space Telescope while exploring the Helix nebula, the closest planetary nebula to Earth at 450 light-years away in the constellation Aquarius. Although ground-based telescopes have revealed such objects, astronomers have never seen so many of them. The most visible knots all lie along the inner edge of the doomed star's ring, trillions of miles away from the star's nucleus. Although these gaseous knots appear small, they're actually huge. Each gaseous head is at least twice the size of our solar system, each tail stretches for 100 billion miles, about 1,000 times the distance between the Earth and the Sun. Astronomers theorize that the doomed star spews hot, lower-density gas from its surface, which collides with cooler, higher-density gas that had been ejected 10,000 years before. The crash fragments the smooth cloud surrounding the star into smaller, denser finger-like droplets, like dripping paint. This image was taken in August, 1994 with Hubble's Wide Field Planetary Camera 2. The red light depicts nitrogen emission ([NII] 6584A), green, hydrogen (H-alpha, 6563A), and blue, oxygen (5007A).

Title The Reflection Nebula in Orion
Full Description Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a nebula in the constellation Orion. The Heritage astronomers, in collaboration with scientists in Texas and Ireland, used Hubble's Wide Field and Planetary Camera 2 (WFPC2) to obtain the color image. NGC 1999 is an example of a reflection nebula. Like fog around a street lamp, a reflection nebula shines only because the light from an imbedded source illuminates its dust, the nebula does not emit any visible light of its own. NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth, in a region of our Milky Way galaxy where new stars are being formed actively. NGC 1999 was discovered some two centuries ago by Sir William Herschel and his sister Caroline, and was cataloged later in the 19th century as object 1999 in the New General Catalogue. This data was collected in January 2000 by the Hubble Heritage Team with the collaboration of star-formation experts C. Robert O'Dell (Rice University), Thomas P. Ray (Dublin Institute for Advanced Study), and David Corcoran (University of Limerick).

Title James C. Elms
Full Description On October 1, 1966, James C. Elms was appointed Director of the NASA Electronics Resource Center in Cambridge, Massachusetts. Elms served as director until the closing of the ERC on June 30, 1970. Prior to his appointment as ERC Director, James Elms served as Deputy Director of NASA Manned Spacecraft Center in Houston, Texas and then as Deputy Associate Administrator for them Manned Spaceflight Program at NASA Headquarters in Washington, DC. The ERC opened in September 1964, taking over the administration of contracts, grants, and other NASA business in New England from the antecedent North Eastern Operations Office (created in July 1962), and closed in June 1970. It served to develop the space agencys in-house expertise in electronics during the Apollo era. A second key function was to serve as a graduate and post- graduate training center within the framework of a regional government-industry-university alliance. Research at the ERC was conducted in ten different laboratories: space guidance, systems, computers, instrumentation research, space optics, power conditioning and distribution, microwave radiation, electronics components, qualifications and standards, and control and information systems. Researchers investigated such areas as microwave and laser communications, the miniaturization and radiation resistance of electronic components, guidance and control systems, photovoltaic energy conversion, information display devices, instrumentation, and computers and data processing. Although the only NASA Center ever closed, the ERC actually grew while NASA eliminated major programs and cut staff in other areas. Between 1967 and 1970, NASA cut permanent civil service workers at all Centers with one exception, the ERC, whose personnel grew annually until its closure in June 1970.
