AUSTIN, Texas — Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the ice sheet’s potentially perilous future.

NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens.
Developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, OnSight will give scientists a means to plan and, along with the Mars Curiosity rover, conduct science operations on the Red Planet. (more…)
New analysis, using data from NASA’s GRAIL spacecraft, has determined that the large dark patch on the western edge of the Moon’s near side is not an impact crater after all.
PROVIDENCE, R.I. [Brown University] — Oceanus Procellarum, a vast dark patch visible on the western edge of the Moon’s near side, has long been a source of mystery for planetary scientists. Some have suggested that the “ocean of storms” is part of a giant basin formed by an asteroid impact early in the Moon’s history. But new research published today in Nature deals a pretty big blow to the impact theory. (more…)
Observations by NASA’s Curiosity Rover indicate Mars’ Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.
This interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet. (more…)
Despite large temperature increases in Alaska in recent decades, a new analysis of NASA airborne data finds that methane is not being released from Alaskan soils into the atmosphere at unusually high rates, as recent modeling and experimental studies have suggested. The new result shows that the changes in this part of the Arctic have not yet had enough impact to affect the global methane budget. (more…)
Brown geoscientist Peter Schultz, a veteran of three NASA missions to comets and asteroids, talks about the European Space Agency’s mission to land on a comet and what the scientific community hopes to learn about these orbiting bodies.
PROVIDENCE, R.I. [Brown University] — On Wednesday, Nov. 12, 2014, the European Space Agency landed a spacecraft on the surface of a comet for the first time. Scientists hope data returned from the Rosetta spacecraft’s Philae Lander might not only offer a new perspective on the nature of comets, but also shed light the evolution of the solar system.

The ruddy color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, according to a new analysis of data from NASA’s Cassini mission. The results contradict the other leading theory for the origin of the spot’s striking color — that the reddish chemicals come from beneath Jupiter’s clouds. (more…)
It might look like a spoked wheel or even a “Chakram” weapon wielded by warriors like “Xena,” from the fictional TV show, but this ringed galaxy is actually a vast place of stellar life. A newly released image from NASA’s Spitzer Space Telescope shows the galaxy NGC 1291. Though the galaxy is quite old, roughly 12 billion years, it is marked by an unusual ring where newborn stars are igniting. (more…)
