MIT 20 Aug 2019, 04:00 UTC Nearly all of the oxygen in our universe is forged in the bellies of massive stars like our sun. As these stars contract and burn, they set off thermonuclear reactions within their cores, where nuclei of carbon and helium can collide and fuse in a rare though essential nuclear reaction that generates much of the oxygen in the universe.
NASA's Jet Propulsion Laboratory News and Features 19 Aug 2019, 20:59 UTC An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the Europa Clipper mission's next phase. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science payload.

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.
