Title Hubble Heritage Project's First Anniversary
General Information What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. To mark the first anniversary of the Hubble Heritage Project, we present four Hubble telescope images of nebulae surrounding stars in our own Milky Way Galaxy. Two of these visible-light pictures show interstellar gas and dust around young stars at the beginning of their lives, and two more show gas ejected from old stars that are nearing the end of theirs. Remarkably, in spite of the completely different evolutionary stages, the nebulae have more striking features in common, including evidence of diametrically opposed gas ejections from both the young and old stars.
Hurricane Felix
Title Hurricane Felix
Description Category 5 hurricanes are rare. Rarer still is the storm that makes landfall as a Category 5 storm—most weaken before hitting land. Yet, exactly two weeks after Hurricane Dean struck the Yucatan Peninsula as a Category 5 storm (the first Atlantic storm of that size to come ashore since Hurricane Andrew in 1992), Hurricane Felix roared ashore at Category 5 strength. Felix came ashore over northeastern Nicaragua on September 4, 2007, with sustained winds of 260 kilometers per hour (160 miles per hour), said the National Hurricane Center. [ http://www.nhc.noaa.gov/ ] Forecasters predicted that Felix would continue to move west over Honduras, El Salvador, Guatemala, and Mexico. Heavy rain in these mountainous regions could trigger devastating floods and mudslides. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image of Hurricane Felix at 12:30 p.m. local time (18:30 UTC) on September 3, 2007. At that time, Felix had already reached Category 5 status, with wind speeds that matched those observed at landfall the following morning. Along the left side of the image is the Central American coastline where Felix would eventually come ashore. The image reveals that Felix was compact, not a sprawling storm, and densely packed with bright clouds. Though cloud-filled, the eye forms a small, dark depression in the center of the storm. The large image provided above has a resolution of 250 meters per pixel, MODIS' maximum resolution. The image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2007246-0903/Felix.A2007246.1830 ] from the MODIS Rapid Response System. You can download a 250-meter-resolution KMZ file of Hurricane Felix [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Sep2007/felix_tmo_2007246.kmz ] suitable for use with Google Earth.

Yet, exactly two weeks after Hurricane Dean struck the Yucatan Peninsula as a Category 5 storm, Hurricane Felix roared ashore as yet another. Felix came ashore over northeastern Nicaragua on September 4, 2007, with sustained winds of 260 kilometers per hour (160 miles per hour), said the National Hurricane Center. [ http://www.nhc.noaa.gov/ ] Forecasters predicted that Felix would continue to move west over Honduras, El Salvador, Guatemala, and Mexico. Heavy rain in these mountainous regions could trigger devastating floods and mudslides. This area is the same region which suffered major damage from Hurricane Mitch in 1998. Though better prepared this time for such a storm, many fear a repeat of Mitch's devastation. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image of Hurricane Felix at 10:10 a.m. local time (16:10 UTC) on September 4, 2007. At that time, Felix had slammed into the mountains of Nicaragua and lost enough power to be rated a Category 3 hurricane, with sustained wind speeds of 200 km/hr (120 mph). The clear eye present on September 3 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14483 ] was gone, but the storm retained the tight spiral shape of a very powerful storm. The large image provided above has a resolution of 250 meters per pixel, MODIS' maximum resolution.

Hurricane Stan Floods Centra …
Title Hurricane Stan Floods Central America
Description By standard measures, Stan was a small storm. It formed as a tropical depression on October 1, 2005, and barely reached hurricane status before going ashore in southern Mexico on October 4. In the intervening period, the storm moved over the Yucatan Peninsula, drenching Belize, Guatemala, Honduras, El Salvador, and Mexico with heavy rain. Though the winds never reached more than 130 kilometers per hour (80 miles per hour), the storm proved to be one of the most devastating since Hurricane Mitch struck the region in 1998. Stan dropped heavy rains on parts of Central America for several days, triggering deadly floods and landslides. This image, made using data collected by the Tropical Rainfall Measuring Mission (TRMM [ http://trmm.gsfc.nasa.gov/ ]) satellite between September 29 and October 5, 2005, shows rainfall totals over the affected countries. The highest rainfall is shown in deep red, while the lightest is in blue. The rainfall data is laid over a topographical map. As this image illustrates, the rain fell over steep mountains. The water released sections of earth, and both water and mud flooded the populated valleys. Floods and mudslides forced thousands from their homes and damaged roads and bridges throughout the region. News reports claim that more than 100 people have died in the floods, but differ on the exact number. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at NASA Goddard Space Flight Center provides estimates of rainfall over the global Tropics. TRMM is a joint mission between NASA and the Japanese space agency JAXA. NASA image produced by Hal Pierce (SSAI/NASA GSFC).
Tropical Storm Adrian
Title Tropical Storm Adrian
Description Tropical Storm Adrian is developing and moving steadily closer to the west coast of Central America. The storm is the first of the 2005 Pacific hurricane season, which runs from May 15 to November 30, and it has the potential to inundate Guatemala, El Salvador, and Honduras with heavy rains. These mountainous regions are prone to mudslides and flash floods. Adrian is not a powerful storm, but it has continued to intensify since it formed on May 17. The National Hurricane Center [ http://www.nhc.noaa.gov/ ] predicts that the storm may become a weak hurricane before it makes landfall late on May 19 or early on May 20. This image of Tropical Storm Adrian was taken on May 19, 2005, by one of the GOES satellites. The GOES sensors maintain a constant watch over a particular section of the Earth to provide important weather information. As such, the GOES satellite can watch the development of the storm. The animation provided above shows the storm as it became more and more organized on May 18. When it blows ashore, Adrian will become only the fifth tropical cyclone to make landfall over Guatemala or El Salvador since 1966, according to the National Hurricane Center. Of those storms, none has ever crossed Central America this early in May, making Adrian unusual. Even more unusual than the timing of this storm is its path. Typically, hurricanes that form in the Eastern Pacific curve west to dissipate over the ocean, or they may move north into Mexico. Adrian is moving east and is expected to make landfall over El Salvador and Guatemala on May 19 or May 20. Its path is predicted to take it over the same region that was devastated by Hurricane Mitch in 1998. Unlike Adrian, Mitch formed in the Atlantic and crossed this section of Central America from the east. If Adrian survives its encounter with the high mountains of Central America, it could re-emerge in the Caribbean and move over Cuba and the Bahamas. While storms occasionally cross from the Atlantic into the Pacific, it is extremely rare for a storm to move into the Atlantic from the Pacific, however.

Mir Flares Farewell
Title Mir Flares Farewell
Explanation Streaking low [ http://www.heavens-above.com/ ] across the western horizon after sunset, the Russian Mir space station [ http://science.nasa.gov/headlines/y2001/ast10mar_1.htm ] makes a final pass through the evening sky above the coastal city of Salvador, Brazil. In this 5 minute 20 second time exposure made with ASA 800 film and a wide-angle lens on March 19, setting stars leave short, almost vertical trails [ http://antwrp.gsfc.nasa.gov/apod/ap990521.html ]. A rapidly moving Mir travels horizontally, trailing toward the left (south) edge of the picture. Reflecting sunlight from low Earth orbit, the historic space station [ http://www.russianspaceweb.com/mir.html ] chanced to produce a "farewell" flare [ http://antwrp.gsfc.nasa.gov/apod/ap991022.html ] near the end of its visible track. As if in poignant response, the Hubble Space Telescope [ http://liftoff.msfc.nasa.gov/temp/HubbleLoc.html ] appeared in Brazilian skies within a minute after Mir's passage [ http://www.russianspaceweb.com/ ] and also left a flare along a trail moving toward the top of the picture. Lights visible [ http://antwrp.gsfc.nasa.gov/apod/ap001127.html ] on the horizon are from nearby Itaparica Island. After 15 years in service, the long-lived Mir [ http://www.russianspaceweb.com/mir_close_calls.html ] space station was safely deorbited today [ http://www2.satellite.eu.org/sat/vsohp/ mir.html ]. The splashdown of its surviving pieces occurred in a remote area of the South Pacific Ocean.
Comet Ikeya-Zhang
Title Comet Ikeya-Zhang
Explanation Comet Ikeya-Zhang [ http://cometography.com/lcomets/2002c1.html ] is presently heading north in planet Earth's sky [ http://encke.jpl.nasa.gov/images/02C1/ c2002c1chart.jpg ], framed by stars of the constellation Cetus. The comet was discovered [ http://cfa-www.harvard.edu/iauc/07800/ 07812.html ] as a faint, telescopic object [ http://encke.jpl.nasa.gov/RecentObs.html#02C1 ] near the western horizon on the evening of February 1st independently by Kaoru Ikeya [ http://comets.amsmeteors.org/comets/ lcomets/1965s1.html ] of Shizuoka prefecture, Japan, Daqing Zhang in Henan province, China, and later by [ http://cfa-www.harvard.edu/iauc/07800/07813.html ] observer Paulo Raymundo of Salvador, Brazil. But Ikeya-Zhang [ http://skyandtelescope.com/observing/objects/comets/ article_477_1.asp ] is expected to brighten significantly and in March and April could become visible to the unaided eye. This picture, taken near Tucson, Arizona, USA on the evening of February 9th, covers a field a bit less than the width of the full moon showing the comet's [ http://encke.jpl.nasa.gov/define.html ] condensed coma [ http://www.ifa.hawaii.edu/faculty/jewitt/ coma.html ] and narrow, developing tail [ http://antwrp.gsfc.nasa.gov/apod/ap001227.html ]. Ikeya-Zhang should pass closest to the Sun (perihelion) on March 18 at a point roughly midway [ http://encke.jpl.nasa.gov/images/02C1/ ikeyaorbit.jpg ] between the orbits of Mercury and Venus. Based on preliminary calculations of this comet's orbit, Ikeya-Zhang [ http://cfa-www.harvard.edu/iau/Ephemerides/Comets/ 2002C1.html ] is suspected of being a periodic comet, returning to the inner Solar System every 500 years or so. In fact, it is "speculated" that Ikeya-Zhang may be directly connected with a historic bright comet [ http://ssd.jpl.nasa.gov/great_comets.html ] seen in 1532.

Title Colored Height and Shaded Relief, Central America
Original Caption Released with Image Panama, Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Belize, southern Mexico and parts of Cuba and Jamaica are all seen in this image from NASA's Shuttle Radar Topography Mission. The dominant feature of the northern part of Central America is the Sierra Madre Range, spreading east from Mexico between the narrow Pacific coastal plain and the limestone lowland of the Yucatan Peninsula. Parallel hill ranges sweep across Honduras and extend south, past the Caribbean Mosquito Coast to lakes Managua and Nicaragua. The Cordillera Central rises to the south, gradually descending to Lake Gatun and the Isthmus of Panama. A highly active volcanic belt runs along the Pacific seaboard from Mexico to Costa Rica. High-quality satellite imagery of Central America has, until now, been difficult to obtain due to persistent cloud cover in this region of the world. The ability of SRTM to penetrate clouds and make three-dimensional measurements has allowed the generation of the first complete high-resolution topographic map of the entire region. This map was used to generate the image. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the north-south direction. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow, red, and magenta, to white at the highest elevations. For an annotated version of this image, please select Figure 1, below:(Large image: ~9 mB jpeg) Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000. The mission used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar that flew twice on the Space Shuttle Endeavour in 1994. The Shuttle Radar Topography Mission was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (200-foot)-long mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C.
