Breakthrough Listen releases 2 petabytes of data from SETI survey of Milky Way

Science Daily Astronomy - 11 hours 13 min ago
Breakthrough Listen announced its second major release of SETI data: a radio survey of the plane of the Milky Way and the galactic center. The public is urged to search the data for signals from intelligent civilizations. A former undergraduate initiated the analysis by looking at emissions from 20 nearby stars that could see Earth transiting our sun. The VLA also signed on to capture radio data for SETI.

Galactic cosmic rays affect Titan's atmosphere

Science Daily Astronomy - Fri, 2020-02-14 13:47
Planetary scientists have revealed the secrets of the atmosphere of Titan, the largest moon of Saturn. The team found a chemical footprint in Titan's atmosphere indicating that cosmic rays coming from outside the Solar System affect the chemical reactions involved in the formation of nitrogen-bearing organic molecules. This is the first observational confirmation of such processes, and impacts the understanding of the intriguing environment of Titan.

Mars: Simulations of early impacts produce a mixed Mars mantle

Science Daily Astronomy - Wed, 2020-02-12 15:01
The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Scientists modeled the mixing of materials associated with these impacts, revealing that the Red Planet may have formed over a longer timescale than previously thought.

Citizen scientists discover rare cosmic pairing

Science Daily Astronomy - Wed, 2020-02-12 12:19
Citizen scientists have uncovered a bizarre pairing of two brown dwarfs, objects much smaller than the Sun that lack enough mass for nuclear fusion. The discovery, confirmed by astrophysicists, shows that brown dwarf systems -- the formation of which are still poorly understood -- can be very low mass and extremely far apart yet inexorably linked.
