Mars Orbiter Shows Gullies on Mars Not Likely Formed by Liquid Water

New Study Shows Mars Gullies Not Formed by Liquid Water

Using data from NASA’s Mars Reconnaissance Orbiter, astronomers show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes. Scientists use the term “gully” for features on […]

Astronomers Reveal the Rotation of the Hot Gas Around the Milky Way

Astronomers Reveal the Dizzying Spin of the Milky Way’s Halo

A team of astronomers has discovered that the hot gas in the halo of the Milky Way galaxy is spinning in the same direction and at comparable speed as the galaxy’s disk, which contains our stars, planets, gas, and dust. This new knowledge sheds light on how individual atoms have assembled into stars, planets, and […]

Researchers Investigate the Lack of Large Impact Craters on Ceres

The Missing Large Impact Craters on Ceres

Ceres’ lack of giant impact basins presents a puzzle to scientists. They expected to observe more large craters on the dwarf planet than have been found by NASA’s Dawn mission. Researchers are investigating a variety of processes that might have caused the appearance of the largest basins to be softened or erased over time. Ceres […]

New Battery Could Overcome Key Drawbacks of Lithium-Air Batteries

New Battery Could Overcome Key Drawbacks of Lithium-Air Batteries

Engineers from MIT propose that a new lithium-oxygen battery material could be packaged in batteries that are very similar to conventional sealed batteries yet provide much more energy for their weight. Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output […]

Astronomers Reveal ‘Orphaned Protostars’

Astronomers Study Protostars at Low Extinction in Orion A

New research from the Harvard-Smithsonian Center for Astrophysics concludes that ten protostellar candidates are indeed protostars even though they are not presently embedded in a cloud. Stars form as gravity contracts the gas and dust in an interstellar cloud until clumps develop that are dense enough to coalesce into stars. Precisely how this happens, however, […]

Spitzer Provides Astronomers with a New Way to See the Milky Way’s Giant Black Hole

Astronomers See the Milky Way's Giant Black Hole with New Eyes

Astronomers are using NASA’s Spitzer Space Telescope to further explore Sagittarius A*. At the center of our Milky Way galaxy lies a cosmic beast called Sagittarius A*. This supermassive black hole packs about four million sun-masses into a volume roughly the size of our solar system. Recently, NASA’s Spitzer Space Telescope began exploring this exotic […]

New View of Saturn’s A and F Rings

New Cassini View of Saturn's A and F Rings

The Cassini Spacecraft gives us another interesting view of Saturn. Saturn’s A and F rings appear bizarrely warped where they intersect the planet’s limb, whose atmosphere acts here like a very big lens. In its upper regions, Saturn’s atmosphere absorbs some of the light reflected by the rings as it passes through. But absorption is […]

New Deep View of the Large and Small Magellanic Clouds

Low Surface Brightness Imaging of the Magellanic System

This newly released ESO image reveals a new view of the Large and Small Magellanic Clouds. Each of the thousands of spots in this new image represents a distant star, and the glittering blue holes reveal glimpses of our neighboring galaxies, the Large and Small Magellanic Clouds. Although this image looks as if it was […]

Hubble Telescope Views Remnants of a Dead Star

Hubble Views Remnants of a Dead Star DEM L316A

This newly released Hubble image captures the remnants of a long-dead star. These rippling wisps of ionized gas, named DEM L316A, are located some 160,000 light-years away within one of the Milky Way’s closest galactic neighbors — the Large Magellanic Cloud (LMC). The explosion that formed DEM L316A was an example of an especially energetic […]

NASA Study Reveals That Historical Records Miss a Fifth of Global Warming

New NASA Study Shows Historical Records Miss a Fifth of Global Warming

New research led by NASA scientists reveals that almost one-fifth of the global warming that has occurred in the past 150 years has been missed by historical records due to quirks in how global temperatures were recorded. The study explains why projections of future climate based solely on historical records estimate lower rates of warming […]

Yale Researchers Cross the “Break Even” Point in Preserving a Bit of Quantum Information

Researchers Cross the Break Even Point in Preserving Quantum Information

Using a novel system to encode, spot errors, decode, and correct errors in a quantum bit, researchers at Yale University have developed a device that lengthens the life of quantum information. For the first time, researchers at Yale have crossed the “break even” point in preserving a bit of quantum information for longer than the […]

Hubble Unveils Galaxies Near and Far

New Hubble Image

Using gravitational lensing, the Hubble Space Telescope unveils a very cluttered-looking universe filled with galaxies near and far. Celebrating its 50th anniversary this year, the TV series “Star Trek” has captured the public’s imagination with the signature phrase, “To boldly go where no one has gone before.” NASA’s Hubble Space Telescope doesn’t “boldly go” deep […]

Engineers Reveal a ‘New Universe’ of Organic Molecules That Can Store Energy in Flow Batteries

A New Battery Inspired by Vitamins

Engineers from Harvard University have identified a whole new class of high-performing organic molecules, inspired by vitamin B2, that can safely store electricity from intermittent energy sources such as solar and wind power in large batteries. The development builds on previous work in which the team developed a high-capacity flow battery that stored energy in […]

Scientists Show How Synapses Are Arranged with Respect to Each Other

How Synapses Are Arranged with Respect to Each Other

For the first time, neurobiologists show that contact points between specific neuron types are clustered in groups on the target neuron. The cerebral cortex resembles a vast switchboard. Countless lines carrying information about the environment, for example from the sensory organs, converge in the cerebral cortex. In order to direct the flow of data into […]

WISE Reveals the X-Shaped Bulge of the Milky Way

X Shape Marks Milky Way’s Central Bulge of Stars

Using data from NASA’s Wide-field Infrared Survey Explorer (WISE) mission, astronomers reveal that the Milky Way’s central bulge of stars forms an “X” shape. The unconventional collaboration started in May 2015 when Dustin Lang, an astronomer at the Dunlap Institute of the University of Toronto, posted galaxy maps to Twitter, using data from WISE’s two […]

Cassini Image Shows Saturn’s Rings with Dione and Epimetheus

New Cassini Image Shows Dione and Epimetheus

This newly released Cassini image shows Saturn’s rings with Dione and Epimetheus off in the distance. Saturn’s main rings, along with its and moons, are much brighter than most stars. As a result, much shorter exposure times (10 milliseconds, in this case) are required to produce an image and not saturate the detectors of the […]

Yale Scientists Recode Organisms to Resist Viral Contamination

Scientists Recode Organisms to Resist Viral Contamination

Scientists from Yale University have discovered a novel way to combat viral contamination of bio-factories that produce a growing number of drugs, chemicals, and fuels. The new method involves recoding organisms to stop horizontal transfer of genes — which viruses use to infect and hijack cellular machinery to reproduce. The study is published in the […]

ALMA Detects Water Snowline Around Young Star V883 Orionis

Water Snowline Around Young Star V883 Orionis

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers has made the first ever resolved observation of a water snow line within a protoplanetary disc. This line marks where the temperature in the disc surrounding a young star drops sufficiently low for snow to form. A dramatic increase in the brightness of the […]
