Telescope Targets Black Holes' Binges And Burps

Originally published on Tue July 31, 2012 5:45 am

The NuSTAR telescope, seen in this artist's illustration, will soon be sending back data that researchers will use to study black holes.

NASA's newest space telescope will start searching the universe for black holes on Wednesday. Scientists hope the NuSTAR X-ray telescope, which launched about six weeks ago and is now flying about 350 miles above the Earth, will help shed some light on the mysteries of these space oddities.

Mission control for the telescope is a small room on the University of California, Berkeley, campus, where about a dozen people with headsets rarely look up from their screens.

Massive Ice Melt In Greenland Worries Scientists

Originally published on Wed July 25, 2012 2:53 pm

Images released Tuesday show the extent of surface melt on Greenland's ice sheet on July 8 (left) and July 12 (right). Measurements from three satellites showed that on July 8, about 40 percent of the ice sheet had undergone thawing at or near the surface. By July 12, 97 percent of the ice sheet surface had thawed.

A pair of NASA satellite images taken just four days apart tells a potentially worrying story of melting ice in the polar summer.

The first, snapped from orbit on July 8, shows about 40 percent of the Greenland ice sheet shaded in pink or red to illustrate probable or confirmed surface melting. The second photo, taken on July 12, shows nearly the entire land mass — 97 percent — blotched in a red hue.

'Heat Dome' Linked To Greenland's Biggest Melt In 30 Years

In these illustrations NASA produced from satellite data, the melt in Greenland on July 8 (at left) and July 12 are shown. According to NASA, "the areas classified as 'probable melt' (light pink) correspond to those sites where at least one satellite detected surface melting. The areas classified as 'melt' (dark pink) correspond to sites where two or three satellites detected surface melting."

Last week there were the pictures of an iceberg twice the size of Manhattan breaking off Greenland's Petermann Glacier.

Now there are NASA images showing that in four days earlier this month, "Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations."
