Image of the Week: The Cratered Moon

January 27, 2015 7:00 am | by ESA | News | Comments

The speckled object depicted here is Callisto, Jupiter’s second largest moon. Similar in appearance to a golf ball, Callisto is covered almost uniformly with pockmarks and craters across its surface, evidence of relentless collisions. In fact, Callisto is the most heavily cratered object in the Solar System.

Research Recreates Planet Formation, Super-earths in Lab

January 23, 2015 7:00 am | by Lawrence Livermore National Laboratory | News | Comments

New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the material properties that determined planets' formation and evolution processes.

Rosetta Yields Closest-ever Look at Comet

January 22, 2015 3:00 pm | by Univ. of Maryland | News | Comments

On Nov. 12, 2014, the Rosetta mission made history when its Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this exciting technical achievement gained lots of headlines, it was only the beginning for researchers back on Earth who are receiving and analyzing comet data. The latest chapter in the story provides the closest and most detailed look at a comet that scientists have ever seen.

Ocean's Dust Sheds Light on Supernovae

January 21, 2015 7:00 am | by Australian National Univ. | News | Comments

Scientists plumbing the depths of the ocean have made a surprise finding that could change the way we understand supernovae, exploding stars way beyond our solar system. The researchers have analyzed extraterrestrial dust, thought to be from supernovae, that has settled on ocean floors to determine the amount of heavy elements created by the massive explosions.

SpaceX Releases Video of Crash Landing's Explosion

January 20, 2015 8:34 am | by Associated Press | Videos | Comments

SpaceX has released dramatic footage of its booster rocket trying to land on a floating ocean barge after a launch — an unprecedented attempt that ended in a fiery explosion. The video shows the 14-story rocket hitting the football field-sized barge at an angle, lighting up the night sky off the Florida coast.

Scientists See Cosmic Burst of Radio Waves

January 20, 2015 7:00 am | by Niels Bohr Institute, Univ. of Copenhagen | News | Comments

A strange phenomenon has been observed by astronomers right as it was happening — a “fast radio burst.” The eruption was described as an extremely short, sharp flash of radio waves from an unknown source in the universe.

New Maps Help Find Global Farmland

January 19, 2015 7:00 am | by International Institute for Applied Systems Analysis | News | Comments

Knowing where agricultural land is located is crucial for regional and global food security planning, and information on field size offers valuable insight into local economic conditions. Two new global maps provide a significant step forward in global cropland information on these two topics.

Researchers Study Quasars in the Early Universe

January 19, 2015 7:00 am | by Univ. of Cambridge | News | Comments

Two teams of astronomers have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars— extremely luminous objects powered by supermassive black holes— regulate the formation of stars and the build-up of the most massive galaxies. They found that a quasar spits out cold gas at speeds up to 2,000 kilometers per second, and across distances of nearly 200,000 light years.

Lost Lander Found on Mars After 11 Years

January 16, 2015 2:00 pm | by ESA | News | Comments

The Beagle-2 Mars lander, which has been lost on Mars since 2003, has been found in images taken by a NASA orbiter at the Red Planet. Beagle-2 was released from its mother craft on Dec. 19, 2003, and was due to land six days later. But nothing was heard from the lander after its scheduled touchdown, and searches for the lander were fruitless.

Research Throws Origin of Asteroids into Doubt

January 15, 2015 7:00 am | by Purdue Univ. | News | Comments

Asteroids may be a byproduct of planet formation rather than planetary building blocks. Research suggests collisions of planetary embryos– the seeds to the planets in our solar system that existed 4 billion years ago– could be the origin of the material that formed asteroids.

ISS Evacuated One Side During Leak Scare Today

January 14, 2015 3:00 pm | by Associated Press, Marcia Dunn | News | Comments

NASA evacuated astronauts from its side of the International Space Station (ISS) today after an alarm indicated a possible toxic leak. Officials later said a false sensor reading or computer problem likely set off the alarm, rather than an actual leak of ammonia coolant.

Motion May Be Key to Finding E.T.

January 14, 2015 7:00 am | by EPFL | Videos | Comments

Scientists have developed an extremely sensitive device that can detect life forms by sensing the slightest motion. The chemistry-free system can be used to rapidly test antibiotics or even to search for life on other planets.

Worm Studies May Keep Astronauts Strong

January 13, 2015 3:00 pm | by NASA | News | Comments

It is said that great things can come in small packages. In this case, one key to keeping astronauts healthy on long-duration space missions may be found in a tiny roundworm barely a millimeter long. Studies on the ISS help researchers seek clues to physiological problems found in astronauts by studying millimeter-long roundworms.

Image of the Week: Bloom Seen Around Island

January 13, 2015 7:00 am | by NASA | News | Comments

The Operational Land Imager on Landsat 8 captured this view of a phytoplankton bloom near Alaska’s Pribilof Islands on Sept. 22, 2014. The Pribilofs are surrounded by nutrient-rich waters in the Bering Sea. The milky green and light blue shading of the water indicates the presence of vast populations of microscopic phytoplankton— mostly coccolithophores, which have chalky calcite scales.

Space Cloud Blocks Out Stars

January 8, 2015 7:00 am | by ESO | News | Comments

Some of the stars appear to be missing in an intriguing new image of space. But the black gap in this glitteringly beautiful star field is not really a gap, but rather a region of space clogged with gas and dust. Such clouds are the birthplaces of future stars.

Levitation, Wax Team to Answer Centuries Old Questions

January 8, 2015 7:00 am | by The Univ. of Nottingham | Videos | Comments

Splash form tektites are tiny pieces of natural glass created out of spinning drops of molten rock flung from the earth during an extra-terrestrial impact. They come in a myriad of shapes and the formation of these shapes has been the subject of scientific investigation for centuries. Now, using magnetic levitation to imitate weightlessness, researchers have manufactured solid wax models of these shapes.
