MIT engineers devise a decision map to identify the best mission type to deflect an incoming asteroid.
University of Washington astronomer Victoria Meadows answers questions about characterizing the atmospheres of terrestrial and potentially Earth-like exoplanets, and searching for signs of life on these worlds, ahead of her talk at the American Association for the Advancement of Science annual meeting in Seattle. Meadows will present in the 'Detecting Life and Extraterrestrial Technologies' session, which begins at 10 a.m. on Saturday, Feb. 15.
Data from a massive search for cosmic radio emission released Feb 14. by the Breakthrough Listen Initiative has allowed astronomers to look for technological signatures of extraterrestrial civilizations that might be looking for us.
Planetary scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) 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.
Breakthrough Listen, based at UC Berkeley, 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 Berkeley 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.
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. Southwest Research Institute 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.
Astronomers using two Maunakea Observatories, W. M. Keck Observatory and Subaru Telescope in Hawaii, have probed the formation process of giant exoplanets and brown dwarfs by using a combination of direct imaging of these objects and custom software to model their orbits.
The majority of stars in the universe will become luminous enough to blast surrounding asteroids into successively smaller fragments using their light alone, according to a University of Warwick astronomer.
Scientists have found a new way to analyze the chemistry of the moon's soil using a single grain of dust brought back by Apollo 17 astronauts in 1972. Their technique can help us learn more about conditions on the surface of the moon and formation of precious resources like water and helium there.
A 'beating heart' of frozen nitrogen controls Pluto's winds and may give rise to features on its surface, according to a new study. Pluto's famous heart-shaped structure, named Tombaugh Regio, quickly became famous after NASA's New Horizons mission captured footage of the dwarf planet in 2015 and revealed it isn't the barren world scientists thought it was.
