A portion of the Sloan detailed night-sky image
Sloan data yields biggest color night-sky image ever
(Jan 12, 2011)

Astronomers have released the largest-ever color image of the whole sky, stitched from seven million images, each made of 125 million pixels. The Sloan Digital Sky Survey's latest effort tops its own record, published publicly for professional astronomers and "citizen scientists" alike. Data from Sloan have helped to identify hundreds of millions of cosmic objects.

A supercluster of galaxies as it appears in Planck data
Planck telescope observes cosmic giants
(Jan 11, 2011)

The Planck space telescope has identified some of the largest structures ever seen in the Universe. These are clusters of galaxies that are gravitationally bound to each other and which measure tens of millions of light-years across. Astronomers say the Planck observatory has made more than 20 detections that are brand new to science.

terrestrial gamma-ray flashes
Antimatter caught streaming from thunderstorms on Earth
(Jan 11, 2011)

A space telescope has accidentally spotted thunderstorms on Earth producing beams of antimatter. Such storms have long been known to give rise to fleeting sparks of light called terrestrial gamma-ray flashes. But results from the Fermi telescope show they also give out streams of electrons and their antimatter counterparts, positrons.

Kepler 10-b
Kepler discovers its first rocky planet
(Jan 10, 2011)

NASA's Kepler mission confirmed the discovery of its first rocky planet, named Kepler-10b. Measuring 1.4 times the size of Earth, it is the smallest planet ever discovered outside our solar system. The discovery of this exoplanet is based on more than eight months of data collected by the spacecraft from May 2009 to early January 2010.

No extra time for US particle lab
(Jan 10, 2011)

The hunt for the elusive Higgs boson particle – crucial to current theories of physics – looks set to become a one-horse race after 2011. A US "particle smasher" has been denied an extension that would have kept it running until 2014. The Tevatron accelerator will now end operations this year as was originally planned.

Henize 2-10
Black holes first?
(Jan 10, 2011)

The co-evolution of supermassive black holes and the even more massive galaxies that host them remains poorly understood. Do the black holes drive the evolution of galaxies around them; or do galaxies naturally nurture the gravitational gobblers at their centers; or perhaps do they come into being together, as a matched pair? A serendipitous discovery in a relatively close-by dwarf galaxy may help answer that question.

Extreme Planet Makover
Extreme Planet Makeover
(Jan 7, 2011)

The "Extreme Planet Makeover" on the NASA/JPL PlanetQuest site lets you roll up your sleeves and create your very own planet. Balance five factors to create an Earth-like habitable world, or get wild and make your own extreme exoplanet. Use the Image Gallery feature to compare your creation with those of other Earthlings. Once you've finished creating the exoplanet of your dreams, download a picture of your custom world for posterity.

Crab Nebula
Mystery flares betray hidden force within Crab Nebula
(Jan 7, 2011)

Forget the Large Hadron Collider: an interstellar dust cloud called the Crab Nebula has been identified as the most powerful known particle accelerator in the universe. But exactly how it boosts particles to record-breaking speeds is a mystery. The finding also adds an extra complication for astronomers who use the Crab to calibrate their instruments.

dividing cell
Cluster model shows how first cells could have divided
(Jan 7, 2011)

One of the great transitions in the history of life took shape when naked genetic material clothed itself and protocells were born. But try to recreate this moment and you quickly hit a stumbling block. A lipid-coated protocell doesn't have the machinery to easily divide in two when the genetic material replicates. Now Kunihiko Kaneko and Atsushi Kamimura, both of the University of Tokyo, have devised a model which may solve the problem.

Plasma jets key to enduring solar mystery
(Jan 7, 2011)

It's been a mystery for more than half a century: why, in the short distance from the Sun's surface to its corona, or outer atmosphere, does the temperature leap from a few thousand to a few million degrees? The answer, researchers say, might lie in hot jets of plasma erupting from the Sun's surface.
