Fires Blaze North of Omsk
Apr 27, 2012 07:57 AM E
April usually brings a sharp increase in fire activity throughout Central Asia, as farmers begin to prep their fields for the coming season. This year is no exception.
Mars
New Form of Mars Lava Flow Dicovered
Apr 26, 2012 16:58 PM E
High-resolution photos of lava flows on Mars reveal coiling spiral patterns that resemble snail or nautilus shells. Such patterns have been found in a few locations on Earth, but never before on Mars. The discovery, made by Arizona State University graduate student Andrew Ryan, is announced in a paper published April 27, 2012, in the scientific journal Science.

Splatters of Molten Rock Signal Period of Intense Asteroid Impacts on Earth
Apr 26, 2012 10:48 AM E
New research reveals that the Archean era - a formative time for early life from 3.8 billion years ago to 2.5 billion years ago - experienced far more major asteroid impacts than had been previously thought, with a few impacts perhaps even rivaling those that produced the largest craters on the Moon, according to a paper published online today in Nature.
Space X
Dragon Expected to Set Historic Course

Apr 26, 2012 08:59 AM E
Some of the oldest galaxies in the Universe have three times more stellar mass, and so many more stars, than all current models of galaxy evolution predict.
'Spherules' Embedded in Rock
Tiny 'Spherules' Reveal Details about Earth's Asteroid Impacts
Apr 25, 2012 15:44 PM E
Researchers are learning details about asteroid impacts going back to the Earth's early history by using a new method for extracting precise information from tiny "spherules" embedded in layers of rock.
Telescope
NASA's Webb Telescope Flight Backplane Section Completed
Apr 25, 2012 10:09 AM E
The center section of the backplane structure that will fly on NASA's James Webb Space Telescope has been completed, marking an important milestone in the telescope's hardware development. The backplane will support the telescope's beryllium mirrors, instruments, thermal control systems and other hardware throughout its mission.
Antarctica
International Team Installs First of 3 Telescopes in Antarctica
Apr 25, 2012 08:00 AM E
A team of scientists representing several international institutions, including Texas A&M University, has succeeded in installing the first of three Antarctic Survey Telescopes (AST3-1) at the Chinese Kunlun Station at Dome Argus, the highest point of the Antarctic Plateau.
Titan's Dense Atmosphere Shrouds the Moon
NASA Research Estimates How Long Titan's Chemical Factory Has Been in Business
Apr 25, 2012 06:54 AM E
Saturn's giant moon Titan hides within a thick, smoggy atmosphere that's well-known to scientists as one of the most complex chemical environments in the solar system. It's a productive "factory" cranking out hydrocarbons that rain down on Titan's icy surface, cloaking it in soot and, with a brutally cold surface tempe...
Cluster
A Cluster Within a Cluster
Apr 25, 2012 06:09 AM E
The star cluster NGC 6604 is shown in this new image taken by the Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. It is often overlooked in favour of its more prominent neighbour, the Eagle Nebula (also known as Messier 16), that lies a mere wingspan away.
Blazar Search
NASA's WISE Mission Sees Skies Ablaze With Blazars
Apr 24, 2012 16:20 PM E
Astronomers are actively hunting a class of supermassive black holes throughout the universe called blazars, thanks to data collected by NASA's Wide-field Infrared Survey Explorer (WISE). The mission has revealed more than 200 blazars and has the potential to find thousands more.
Cassini Sees New Objects Blazing Trails in Saturn Ring
Apr 24, 2012 10:26 AM E
Queen Mary scientists working with images from NASA's Cassini spacecraft have discovered strange half-mile-sized objects punching through parts of Saturn's F ring, leaving glittering trails behind them.
Hubble
Hubble's Panoramic View of a Turbulent Star-making Region
Apr 24, 2012 09:32 AM E
Several million stars are vying for attention in this NASA/ESA Hubble Space Telescope image of a raucous stellar breeding ground in 30 Doradus, located in the heart of the Tarantula nebula.
Artic ice
Latest CryoSat Result about Artic Ice Revealed
Apr 24, 2012 06:36 AM E
After nearly a year and a half of operations, CryoSat has yielded its first seasonal variation map of Arctic sea-ice thickness. Results from ESA's ice mission were presented today at the Royal Society in London.
