“Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system.”
Using the Hubble Space Telescope, astronomers have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the

“The young age of the small scarps means that Mercury joins Earth as a tectonically active planet, with new faults likely forming today as Mercury’s interior continues to cool and the planet contracts.”
New research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet. Images obtained by NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft reveal previously undetected small fault scarps— cliff-like landforms tha

“So the rest of the X-rays must come from the Local Hot Bubble, proving that it exists.”
New research confirms some of our ideas about where cosmic X-rays come from and reveals an entire group of X-rays that don’t come from any known source. In the last century, humans realized that space is filled with types of light we can’t see – from infrared signals released by hot stars and

“We were helped in the analysis by the almost perfect alignment of the foreground binary stars with the background star, which greatly magnified the light and allowed us to see the signal of the two stars.”
Using the Hubble Space Telescope, a team of astronomers has confirmed the existence of a planet orbiting two stars in the system OGLE-2007-BLG-349, located 8,000 light-years away towards the center of our galaxy. The planet orbits roughly 300 million miles from the stellar duo, about the dist

Located in Titan’s stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene, an ingredient in the chemical cocktail that colors the giant moon’s hazy, brownish-orange atmosphere.
New research examines the appearance of a cloud of dicyanoacetylene ice in Titan’s stratosphere. The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought -- possibly similar to one seen over Eart

“The bacteria are delivered and they adhere to the intestinal wall, where they survive much better than noncoated bacteria.”
By coating bacteria with polymer layers that protect them from the acids and bile salts found in the digestive tract, scientists from MIT have developed a new strategy for delivering large numbers of beneficial bacterial to the human gut. The human digestive tract contains trillions of bacter

Tardis uses chip space more efficiently than existing memory management schemes because it coordinates cores’ memory operations according to “logical time” rather than chronological time.
Engineers from MIT have found a new way of managing memory on computer chips, using circuit space much more efficiently and more consistent with existing chip designs. A year ago, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory unveiled a fundamentally new way o

New ALMA observations are significantly deeper and sharper than previous surveys at millimeter wavelengths. They clearly show how the rate of star formation in young galaxies is closely related to their total mass in stars.
Using the Atacama Large Millimeter/submillimeter Array, international teams of astronomers explore the distant corner of the Universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF). New ALMA observations are significantly deeper and sharper than previous surveys at

In the last decade, comparative genomic studies have identified small regions of the human genome that are shared with many species but that changed relatively rapidly during the evolutionary divergence of humans from chimpanzees, our closest living relatives.
New research from Harvard Medical School suggests that mutations in genetic regulatory elements may be important in both autism spectrum disorder and human evolution. Small regions of the genome where humans have diverged from chimpanzees contain a variety of mutations implicated in autism an

Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa.
NASA will host a teleconference at 2 p.m. EDT Monday, September 26, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa. Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence

Migrating Exoplanets
Astronomers from the Harvard-Smithsonian Center for Astrophysics take a closer look at migrating exoplanets. Many known exoplanets orbit close to their host star, within one-tenth of an astronomical unit (one AU is the average distance of the Earth from the Sun). Since their orbital periods a

NGC 1052 is an elliptical galaxy at a distance of about 60 million light years in the direction of the constellation Cetus (the Whale).
A team of researchers has measured the magnetic fields in the vicinity of the supermassive black hole at the center of NGC 1052. Two particle jets shoot out from the heart of active galaxy NGC 1052 at the speed of light, apparently originating in the vicinity of a massive black hole. A team o
