Date 4/24/01
Description In honor of the 11th birthday of NASA's Hubble Space Telescope, and by popular demand, the Hubble team has released this new image of the Horsehead nebula, taken by its Wide Field and Planetary Camera 2 (WFPC2), designed and built by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Last year, 5,000 online voters, including students, teachers, and professional and amateur astronomers, chose the nebula as an astronomical target for Hubble to observe. Rising from a sea of dust and gas like a giant seahorse, the Horsehead nebula is one of the most photographed objects in the sky. Hubble's WFPC2 camera took a close-up look at this heavenly icon, revealing the cloud's intricate structure. The Horsehead, also known as Barnard 33, is a cold, dark cloud of gas and dust silhouetted against the bright red nebula IC 434. The bright area at the top left edge is a young star still embedded in its nursery of gas and dust. But radiation from this hot star is eroding the stellar nursery. The top of the nebula also is being sculpted by radiation from a massive star located out of Hubble's field-of-view. The nebula was first discovered on a photographic plate in the late 1800s. It is located in the constellation Orion just south of the bright star Zeta Orionis, which is easily visible to the unaided eye as the left-hand star in the line of three that form Orion's Belt. This image was composed by the Hubble Heritage Team at the Space Telescope Science Institute, Baltimore, Md. The team superimposed Hubble data onto ground-based data taken by Nigel A. Sharp at the .9-meter (35-inch) telescope at the National Science Foundation's Kitt Peak National Observatory near Tucson, Ariz. Additional images and an animation of the Horsehead nebula are available at http://heritage.stsci.edu/public/2001may/supplemental.html . NASA's Hubble Space Telescope was launched on April 24, 1990. The Hubble is a project of international cooperation between NASA and the European Space Agency (ESA). JPL, which designed and built the WFPC2 camera, is a division of the California Institute of Technology in Pasadena. Additional information about the Hubble Space Telescope and more images are available at http://www.stsci.edu . More information about WFPC2 is at http://wfpc2.jpl.nasa.gov .

Title Mars Kicks Up the Dust as it Makes Closest Approach to Earth
General Information What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. NASA's Hubble Space Telescope snapped this picture of Mars on October 28, within a day of its closest approach to Earth on the night of October 29. The large regional dust storm appears as the brighter, redder cloudy region in the middle of the planet's disk. This storm, which measures 930 miles (1500 km) has been churning in the planet's equatorial regions for several weeks now, and it is likely responsible for the reddish, dusty haze and other dust clouds seen across this hemisphere of the planet. Hubble's Advanced Camera for Surveys High Resolution Imager took this image when the red planet was 43 million miles (69 million km) from Earth. Mars won't be this close again to Earth until 2018. Mars is now in its warmest months, closest to the Sun in its orbit, resulting in a smaller than normal south polar ice cap which has largely sublimated with the approaching summer.

Title Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006
Abstract Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. As more ice moves from glaciers on land into the ocean, ocean sea levels raise. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This animation shows the glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006. This animation is an update of and extension to animation ID #3374. In this version, a pause is added on the approach to the Jakobshavn glacier in order to highlight the meltwater lakes visible on the Greenland ice sheet. In addition, semi-transparent overlays and text indicate different regions of the glacier before the calving lines are shown. After the calving front retreat, an additional segment shows a zoom to a global view. During the pull out, historic calving front locations are shown followed by a color overlay showing regions of increase and decrease in the Greenland ice sheet.

Title Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006 with Blue/White Elevation Change over Greenland
Abstract Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier gradually receded until about 1950, where it remained stable for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. As more ice moves from glaciers on land into the ocean, ocean sea levels raise. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This animation shows the glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006. This animation is an update of, and extension to, animation IDs #3374 and #3434. In this version, the pause on the approach to the Jakobshavn glacier where the meltwater lakes on the Greenland ice sheet are visible is shortened. In addition, the colors showing regions of elevation increase and decrease over the Greenland ice sheet are modified.
