Supersized Disk
Title Supersized Disk
Description This illustration compares the size of a gargantuan star and its surrounding dusty disk (top) to that of our solar system. Monstrous disks like this one were discovered around two "hypergiant" stars by NASA's Spitzer Space Telescope. Astronomers believe these disks might contain the early "seeds" of planets, or possibly leftover debris from planets that already formed. The hypergiant stars, called R 66 and R 126, are located about 170,000 light-years away in our Milky Way's nearest neighbor galaxy, the Large Magellanic Cloud. The stars are about 100 times wider than the sun, or big enough to encompass an orbit equivalent to Earth's. The plump stars are heavy, at 30 and 70 times the mass of the sun, respectively. They are the most massive stars known to sport disks. The disks themselves are also bloated, with masses equal to several Jupiters. The disks begin at a distance approximately 120 times greater than that between Earth and the sun, or 120 astronomical units, and terminate at a distance of about 2,500 astronomical units. Hypergiant stars are the puffed-up, aging descendants of the most massive class of stars, called "O" stars. The stars are so massive that their cores ultimately collapse under their own weight, triggering incredible explosions called supernovae. If any planets circled near the stars during one of these blasts, they would most likely be destroyed. The orbital distances in this picture are plotted on a logarithmic scale. This means that a given distance shown here represents proportionally larger actual distances as you move to the right. The sun and planets in our solar system have been scaled up in size for better viewing.

The Tarantula Nebula
Title The Tarantula Nebula
Description NASA's new Spitzer Space Telescope, formerly known as the Space Infrared Telescope Facility, has captured in stunning detail the spidery filaments and newborn stars of the Tarantula Nebula, a rich star-forming region also known as 30 Doradus. This cloud of glowing dust and gas is located in the Large Magellanic Cloud, the nearest galaxy to our own Milky Way, and is visible primarily from the Southern Hemisphere. This image of an interstellar cauldron provides a snapshot of the complex physical processes and chemistry that govern the birth -- and death -- of stars. At the heart of the nebula is a compact cluster of stars, known as R136, which contains very massive and young stars. The brightest of these blue supergiant stars are up to 100 times more massive than the Sun, and are at least 100,000 times more luminous. These stars will live fast and die young, at least by astronomical standards, exhausting their nuclear fuel in a few million years. The Spitzer Space Telescope image was obtained with an infrared array camera that is sensitive to invisible infrared light at wavelengths that are about ten times longer than visible light. In this four-color composite, emission at 3.6 microns is depicted in blue, 4.5 microns in green, 5.8 microns in orange, and 8.0 microns in red. The image covers a region that is three-quarters the size of the full moon. The Spitzer observations penetrate the dust clouds throughout the Tarantula to reveal previously hidden sites of star formation. Within the luminescent nebula, many holes are also apparent. These voids are produced by highly energetic winds originating from the massive stars in the central star cluster. The structures at the edges of these voids are particularly interesting. Dense pillars of gas and dust, sculpted by the stellar radiation, denote the birthplace of future generations of stars. The Spitzer image provides information about the composition of the material at the edges of the voids. The surface layers closest to the massive stars are subject to the most intense stellar radiation. Here, the atoms are stripped of their electrons, and the green color of these regions is indicative of the radiation from this highly excited, or 'ionized,' material. The ubiquitous red filaments seen throughout the image reveal the presence of molecular material thought to be rich in hydrocarbons. The Tarantula Nebula is the nearest example of a 'starburst' phenomenon, in which intense episodes of star formation occur on massive scales. Most starbursts, however, are associated with dusty and distant galaxies. Spitzer infrared observations of the Tarantula provide astronomers with an unprecedented view of the lifecycle of massive stars and their vital role in regulating the birth of future stellar and planetary systems.

Title Supernova SN1987A in the Large Magellanic Cloud
Full Description Glittering stars and wisps of gas create a breathtaking backdrop for the self-destruction of a massive star, called supernova 1987A, in the Large Magellanic Cloud, a nearby galaxy. Astronomers in the Southern hemisphere witnessed the brilliant explosion of this star on Feb. 23, 1987. Shown in this NASA Hubble Space Telescope image, the supernova remnant, surrounded by inner and outer rings of material, is set in a forest of ethereal, diffuse clouds of gas. This three-color image is composed of several pictures of the supernova and its neighboring region taken with the Wide Field and Planetary Camera 2 in Sept. 1994, Feb. 1996 and July 1997. The many bright blue stars nearby the supernova are massive stars, each more than six times heftier than our Sun. They are members of the same generation of stars as the star that went supernova about 12 million years ago. The presence of bright gas clouds is another sign of the youth of this region, which still appears to be a fertile breeding ground for new stars. In a few years the supernova's fast moving material will sweep the inner ring with full force, heating and exciting its gas, and will produce a new series of cosmic fireworks that will offer a striking view for more than a decade.

Title Hubble's Improved Optics Reveal Incredible Detail in Giant Cloud of Gas and Dust
General Information What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. An image of a star-forming region in the 30 Doradus nebula, surrounding the dense star cluster R136. The image was obtained using the second generation Wide Filed and Planetary Camera (WFPC-2), installed in the Hubble Space Telescope during the STS-61 Servicing Mission. The WFPC-2 contains modified optics to correct for the aberration of the Hubble's primary mirror. The new optics will allow the telescope to tackle many of the most important scientific programs for which the it was built, but had to be temporarily shelved with the discovery of the spherical aberration in 1990.

Astronomers explain their Hubble discoveries at a press conference, called a Space Science Update (SSU), broadcast on NASA television. The SSU includes a question and answer session with members of the media. Dramatic pictures of eerie disks of dust encircling young stars are giving astronomers a new look at what may be the early formative stages of planetary systems. Although these pictures from the Hubble telescope don't show planets, the edge-on disks seen by the telescope provide some of the clearest views to date of potential planetary construction zones, say researchers. The images also offer a peek at what happened 4.5 billion years ago when the Earth and other planets in our solar system began to condense out of a pancake-shaped disk of dust and gas centered on the young Sun. These images were taken by Hubble's infrared camera. All of the objects in these pictures are extremely young stars, buried in the centers of these pictures.

General Information What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. Swirls of gas and dust reside in this ethereal-looking region of star formation imaged by NASA's Hubble Space Telescope. This majestic view of LH 95, located in the Large Magellanic Cloud, reveals a region where low-mass, infant stars and their much more massive stellar neighbors reside. A shroud of blue haze gently lingers amid the stars. The image was taken in March 2006 with Hubble's Advanced Camera for Surveys.

Title Hubble Space Telescope Images of a Bright Star in the Large Magellanic Cloud
General Information What is an Early Release Observation? A photograph of a celestial object that demonstrates the performance of a new Hubble camera. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. These three images are of a very bright (Wolf-Rayet) star, Melnick 34, located in the giant star-forming region called 30 Doradus in the Large Magellanic Cloud. In the background are a number of fainter stars that are comparable in brightness to our Sun. A ground-based telescope captured the image at left. Hubble's first-generation visible-light camera, the Wide Field and Planetary Camera, snapped the center picture before the telescope's blurred vision was corrected. The image at right was taken by Hubble's new visible-light camera, the Wide Field and Planetary Camera 2, which is equipped with a corrective optics system. In this new image the star appears sharper, and a larger number of fainter stars are visible.

Title NGC1850: Star Cluster in the LMC
Explanation NGC1850 is a large cluster of stars located a mere 166,000 light-years from Earth in our neighboring galaxy the Large Magellanic Cloud [ http://antwrp.gsfc.nasa.gov/apod/ap000222.html ] (LMC). The colors [ http://aibn47.astro.uni-bonn.de/~gallery/articles/ color.html ] in this beautiful Hubble Space Telescope composite image [ http://oposite.stsci.edu/pubinfo/PR/94/40.html ] of the cluster reveal [ http://antwrp.gsfc.nasa.gov/apod/ap990312.html ] different populations of stars. Yellowish stars are the main cluster stars, sun-like main sequence hydrogen burners [ http://antwrp.gsfc.nasa.gov/htmltest/gifcity/msblues.html ] about 50 million years old. The white stars are massive, hotter, and younger, about 4 million years old. Radiating strongly in ultraviolet light, they represent a loose cluster [ http://www.seds.org/messier/cluster.html ] themselves, perhaps within 200 light-years of the main cluster. Massive stars [ http://antwrp.gsfc.nasa.gov/apod/ap960509.html ] which formed in the older main cluster have long since disappeared, ending their lives in spectacular supernova explosions [ http://antwrp.gsfc.nasa.gov/apod/ap970225.html ]. Did expanding debris from these supernovae trigger the formation [ http://antwrp.gsfc.nasa.gov/apod/ap000219.html ] of the nearby younger cluster? Probably so. In any event, a few million years from now a similar fate awaits the massive stars of the younger cluster - burning brightly but briefly before they explode sending new clouds of stellar debris [ http://antwrp.gsfc.nasa.gov/apod/ap990725.html ] into space.

Title The Tarantula and the Supernova
Explanation In this close-up of the Large Magellanic Cloud [ http://antwrp.gsfc.nasa.gov/apod/ap950918.html ], the spidery looking nebula on the left is fittingly known as as the Tarantula nebula. It is an emission nebula [ http://antwrp.gsfc.nasa.gov/apod/lib/glossary.html#emis_neb ] surrounding a cluster of hot, young stars called the 30 Doradus super cluster. This cluster may contain the most massive stars known (about 50 times the mass of the Sun). Such massive stars put out more than 100 times as much energy as our Sun. The bright "star" (lower right) is actually Supernova 1987a [ http://antwrp.gsfc.nasa.gov/apod/ap950621.html ] and is a harbinger of things to come for the stars within the Tarantula. Massive stars burn their nuclear fuel at drastically enhanced rates to support their high energy output. As a result their lives last only a few million years compared to the Sun's few billions of years. They end in a spectacular death explosion, a supernova [ http://antwrp.gsfc.nasa.gov/apod/lib/glossary.html#sn ], like the star which exploded in 1987 as seen above. Supernovae may leave behind imploded stellar cores which form neutron stars [ http://antwrp.gsfc.nasa.gov/apod/lib/glossary.html#ns ] or black holes [ http://cossc.gsfc.nasa.gov/htmltest/rjn_bht.html ].

Title LMC X-1: A Black Hole Candidate
Explanation The strongest source of X-rays [ http://antwrp.gsfc.nasa.gov/apod/lib/glossary.html#X-ray ] in the Large Magellanic Cloud [ http://antwrp.gsfc.nasa.gov/apod/ap950918.html ] originates from an unusually energetic binary star system [ http://antwrp.gsfc.nasa.gov/apod/ap951226.html ]. This strong source, dubbed LMC X-1, is thought to be a normal and compact star orbiting each other. Gas [ http://antwrp.gsfc.nasa.gov/apod/lib/glossary.html#hydrogen ] stripped of the normal star falls onto the compact star, heats up, and emits X-rays. The X-rays shining from the system knock electrons off atoms for light years around, causing some atoms to glow noticeably in X-rays when the electrons re-combine. Motion in the binary system indicates the compact star is probably a black hole [ http://antwrp.gsfc.nasa.gov/apod/ap951127.html ], since its high mass - roughly five times that of our Sun [ http://antwrp.gsfc.nasa.gov/apod/ap950813.html ] - should be enough to cause even a neutron star [ http://antwrp.gsfc.nasa.gov/apod/ap951122.html ] to implode.

Title Henize 70: A SuperBubble In The LMC
Explanation Massive stars [ http://antwrp.gsfc.nasa.gov/apod/ap951027.html ] (tens of times the mass of the Sun) profoundly affect their galactic environment. Churning and mixing the clouds of gas and dust between the stars, they leave their mark [ http://antwrp.gsfc.nasa.gov/apod/ap960509.html ] in the compositions and locations of future generations of stars and star systems. Dramatic evidence of this is beautifully illustrated in our neighboring galaxy, the Large Magellanic Cloud [ http://antwrp.gsfc.nasa.gov/apod/ap950918.html ] (LMC), by the lovely ring shaped nebula, Henize [ http://spacsun.rice.edu/~henize/karlhenize.html ] 70 (also known as N70 and DEM301 [ http://www.ast.cam.ac.uk/~oey/thesisabs.html ]). It is actually a luminous "superbubble" of interstellar gas about 300 lightyears in diameter, blown by winds from hot, massive stars [ http://www.bartol.udel.edu/~cranmer/hotstar_home.html ] and supernova explosions [ http://legacy.gsfc.nasa.gov/docs/snr.html ], its interior filled with tenuous hot expanding gas. These superbubbles offer astronomers a chance to explore [ http://www.ast.cam.ac.uk/~oey/oeypubs.html ] this crucial connection between the lifecycles of stars and the evolution of galaxies.
