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 […]

Hubble Reveals the Vibrant Core of Galaxy NGC 3125

Hubble Views Galaxy NGC 3125

This newly released Hubble image reveals the vibrant core of the galaxy NGC 3125, which is located 50 million light-years away. Discovered by John Herschel in 1835, NGC 3125 is a great example of a starburst galaxy — a galaxy in which unusually high numbers of new stars are forming, springing to life within intensely […]

Chandra Reveals Evidence for Violent Stellar Merger

Astronomers Find Evidence for Violent Stellar Merger

Using data from Chandra, astronomers have the strongest evidence to date that violent stellar mergers produce pencil-thin jets. This result has implications for estimating the number of such mergers that may detected with gravitational wave observatories. Gamma-ray bursts, or GRBs, are some of the most violent and energetic events in the Universe. Although these events […]

A Quiet Space in the Core of the Perseus Cluster

Astronomers Study the Quiet Intracluster Medium in the Core of the Perseus Cluster

Using the Hitomi satellite astronomers find that turbulence in the central region of the Perseus cluster is low, implying that errors in previous measurements of the masses of galaxy clusters using X-ray observations are small. Most galaxies lie in clusters, groupings of a few to many thousands of galaxies. Our Milky Way galaxy itself is […]

New Research Opens New Realms of Light-Matter Interaction

MIT Study Opens New Realms of Light-Matter Interaction

A new study from MIT shows that some “forbidden” light emissions are in fact possible, and could enable new sensors and light-emitting devices. A new MIT study could open up new areas of technology based on types of light emission that had been thought to be “forbidden,” or at least so unlikely as to be […]

New Map Measures the Effects of Dark Energy in the Expansion of the Universe

Astronomers Measure Dark Energy

A new study details the results from the largest-ever, three-dimensional map of distant galaxies. The map is one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe. “We have spent five years collecting measurements of 1.2 million galaxies over one quarter of the sky to map […]
