NASA's Goddard Space Flight Center 16 Aug 2019, 19:44 UTC NASA’s Robotic Refueling Mission 3 (RRM3) completed an initial set of tool operations, bringing the idea of using water ice or methane from other worlds as fuel for spacecraft one step closer to reality. The ability to store and transfer cryogens (super-cold hydrogen, oxygen and methane) will help spacecraft journey father into our solar system and beyond.
NASA's Goddard Space Flight Center 16 Aug 2019, 11:30 UTC Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly not algae or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off by an aging star. The star is visible in the orb's center, shining through the gases it formerly held onto for most of its stellar life.
NASA's Goddard Space Flight Center 15 Aug 2019, 14:00 UTC If our eyes could see high-energy radiation called gamma rays, the Moon would appear brighter than the Sun! That’s how NASA’s Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade.

NCCR PlanetS 14 Aug 2019, 17:03 UTC New interior models of Jupiter based on data gathered by NASA’s Juno mission suggested that the giant gas planet might not have a small compact core but rather a diluted, “fuzzy” one. Now, an international team with researchers of the University of Zürich and the NCCR PlanetS has found an explanation for this surprising Juno result. A giant impact occurring shortly after Jupiter’s formation may have disrupted and diluted its original compact core.
NASA's Jet Propulsion Laboratory News and Features 13 Aug 2019, 20:22 UTC On July 24, 1969, Apollo 11 command module Columbia splashed down in the Pacific, fulfilling President Kennedy's goal to land a man on the Moon and return him safely to Earth. Among the mission's many firsts was the acquisition and return of the first samples from another celestial body. Findings based on the 47 pounds (21.5 kilograms) of lunar rock and soil rewrotethe textbooks on both the Moon and solar system, and the samples are still being studied today by researchers using new and more sensitive instruments.
Carl Sagan Institute 13 Aug 2019, 18:43 UTC Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell research.
NASA Breaking News 12 Aug 2019, 19:26 UTC After months grappling with the rugged reality of asteroid Bennu’s surface, the team leading NASA’s first asteroid sample return mission has selected four potential sites for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to “tag” its cosmic dance partner.
ESA Top News 12 Aug 2019, 12:45 UTC Last week marked five years since ESA’s Rosetta probe arrived at its target, a comet named 67P/Churyumov-Gerasimenko (or 67P/C-G). Tomorrow, 13 August, it will be four years since the comet, escorted by Rosetta, reached its perihelion – the closest point to the Sun along its orbit. This image, gathered by Rosetta a couple of months after perihelion, when the comet activity was still very intense, depicts the nucleus of the comet with an unusual companion: a chunk of orbiting debris (circled).
NASA's Goddard Space Flight Center 9 Aug 2019, 11:30 UTC The pair of strange, luminescent creatures at play in this image are actually galaxies — realms of millions upon millions of stars.
