| Title |
The Carina Nebula: Star Birth in the Extreme |
| General Information |
What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. In celebration of the 17th anniversary of the launch and deployment of NASA's Hubble Space Telescope, a team of astronomers is releasing one of the largest panoramic images ever taken with Hubble's cameras. READ: Junior version of this article Amazing Space Learn about this story in the Star Witness, a science newspaper available on our sister site, Amazing Space. [ http://amazing-space.stsci.edu/news/archive/2007/02/ ] It is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth —, and death —, is taking place. This image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble's Advanced Camera for Surveys. The Hubble images were taken in the light of neutral hydrogen during March and July 2005. Color information was added with data taken in December 2001 and March 2003 at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission. |

| 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. |

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. |

| Title |
Antarctic Plumbing: Lake Englehardt's Subglacial Hydraulic System |
| Abstract |
ICESat satellite laser altimeter elevation profiles from 2003-2006 collected over West Antarctica reveal numerous regions of temporally varying elevation. MODIS satellite imagery over roughly the same time period collaborates where these subglacial fluctuations have occurred. These observations have led scientists to conclude that subglacial water movement is happening in this lake region, revealing a widespread, dynamic subglacial water system that could provide important insights into ice flow and the mass balance of Antarctica's ice. |

Snow in Arizona
| Title |
Snow in Arizona |
| Description |
After a record 143 days without measurable precipitation, Phoenix, Arizona, received a record 1.40 inches of rain on March 11, 2006, the National Weather Service [ http://www.wrh.noaa.gov/psr/climate/records/dry.php ] reported. In the mountains and highlands of northern and eastern Arizona, the precipitation fell in the form of snow. Temperatures were cool enough that much of the snow remained on March 14, 2006, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image. Snow covers most of northeastern Arizona except for the Painted Desert, the finger of pink that extends into the snowfield. In northwest Arizona, snow flanks the Grand Canyon, but the canyon itself is clear. The snowfall extended north into Utah and Colorado and east into New Mexico. Though the rain and snow were a welcome respite, the storm couldn't deliver enough moisture to break the four-month-long drought [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13410 ] that has gripped the region. The record dry spell was unusual not only because of its length, but also because of its timing. Most of the rain that falls in the Desert Southwest typically falls between November and February, but in 2005 and 2006, those months were dry.
