Solar system formation in two steps

IMAGE: The inner terrestrial protoplanets accrete early, inherit a substantial amount of radioactive 26Al, and hence melt, form iron cores, and degas their primordial volatile abundances rapidly. The outer Solar System... view more  Credit: Mark A Garlick/markgarlick.com An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the…

Graduate student groups from 15 states awarded for science policy initiatives...

Research!America and the Rita Allen Foundation are pleased to announce the recipients of the 2021 Civic Engagement Microgrant Initiative. Now in its third year, the microgrant program provides funding to graduate student and postdoc-led science policy groups from across the U.S. to develop and lead outreach activities in their local communities. The 2021 Civic Engagement Microgrant Initiative is providing funding for 19 groups whose projects…

NASA TV Coverage Set for Upcoming Spacewalks, Preview News Conference

Two NASA astronauts are scheduled to venture outside the International Space Station Wednesday, Jan. 27, and Monday, Feb. 1, for a pair of spacewalks to finish installing a European science platform and complete long-term battery upgrade work.

Hubble pinpoints supernova blast

IMAGE: Featured in this Hubble image is an expanding, gaseous corpse -- a supernova remnant -- known as 1E 0102.2-7219. It is the remnant of a star that exploded long ago... view more  Credit: NASA, ESA, and J. Banovetz and D. Milisavljevic (Purdue University) The NASA/ESA Hubble Space Telescope has observed the supernova remnant named 1E 0102.2-7219. Researchers are using Hubble's imagery of the remnant object…

Study: X-Rays surrounding ‘Magnificent 7’ may be traces of sought-after particle

IMAGE: An artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels... view more  Credit: D. Ducros; ESA/XMM-Newton, CC BY-SA 3.0 IGO A new study, led by a theoretical physicist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called…

Researchers rewind the clock to calculate age and site of supernova...

IMAGE: This Hubble Space Telescope portrait reveals the gaseous remains of an exploded massive star that erupted approximately 1,700 years ago.

Rare star’s giant gamma-ray burst GRB 200415A captured close to our...

Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. But sometimes a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. In fact, the most powerful explosions in the universe are gamma-ray bursts. Now scientists have shown that GRB 200415A came from another possible source for short GRBs. It erupted from a very rare, powerful neutron…

NASA missions unmask magnetar eruptions in nearby galaxies

IMAGE: The giant flare, cataloged as GRB 200415A, reached detectors on different NASA spacecraft at different times. Each instrument pair established its possible location in different swaths of the sky, but... view more  Credit: NASA's Goddard Space Flight Center and Adam Block/Mount Lemmon SkyCenter/University of Arizona On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA…
