Thanks to images from NASA's Cassini spacecraft of a 500-mile-long mountain on Saturn's moon Dione, scientists have found more evidence for the idea that Dione was likely geologically active in the past. It could still be active now.
The spacecraft's magnetometer has detected a faint particle stream coming from the moon, and images showed evidence for a possible liquid or slushy layer under its rock-hard ice crust.
Data from NASA's Wide-field Infrared Survey Explorer (WISE) have led to a new and improved family tree for asteroids in the main belt between Mars and Jupiter.
The findings are a critical step in understanding the origins of asteroid families, and the collisions thought to have created these rocky clans.
During this year’s hurricane season NASA will “double-team” on research with two unmanned Global Hawk aircraft winging their way over storms that develop during the peak of the season. NASA's Hurricane and Severe Storm Sentinel, or HS3 airborne mission, will revisit the Atlantic Ocean to investigate storms using additional instruments and for the first time two Global Hawks.
In late June 2013, NASA will launch a new set of eyes to offer the most detailed look ever of the sun’s lower atmosphere, called the interface region. This region is believed to play a crucial role in powering the sun’s dynamic million-degree atmosphere, the corona. The Interface Region Imaging Spectrograph or IRIS mission will provide the best resolution so far of the widest range of temperatures for of the interface region, an area that has historically been difficult to study.
Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects.
This neutron star, 1E 2259+586, is located about 10,000 light-years away toward the constellation Cassiopeia. It is one of about two dozen neutron stars called magnetars, which have very powerful magnetic fields and occasionally produce high-energy explosions or pulses.
As NASA ventures farther into space, whether redirecting an asteroid or sending astronauts to Mars, the agency will need to make improvements in life support systems, including how to feed the crew during those long deep space missions.
NASA's Advanced Food Technology program is interested in developing methods that will provide food to meet safety, acceptability, variety, and nutritional stability requirements for long exploration missions.
Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws.
The results show that cold gas -- fuel for stars -- spirals into the cores of galaxies along filaments, rapidly making its way to their "guts." Once there, the gas is converted into new stars, and the galaxies bulk up in mass.
The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist.
The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers.
A massive and rare merging of two galaxies has been spotted in images taken by the Herschel space observatory, a European Space Agency mission with important NASA participation.
The findings help explain a mystery in astronomy: whether elliptical galaxies built up slowly over time through the acquisitions of smaller galaxies, or formed more rapidly through powerful collisions between two large galaxies.
NASA Associate Administrator for Education Leland Melvin was honored Tuesday night for his ongoing commitment to inspiring America's students. CITYarts recognized Melvin with the For Making a Difference award during its 45th anniversary gala in New York City.
Melvin leads NASA's education efforts, particularly those related to science, technology, engineering and mathematics, or STEM. Recently, he has expanded his message to students and teachers to include the arts.
