We interview a pair of scientists who have examined microorganisms embedded in halite crystals to determine the feasibility of finding similar evidence of past life in return samples from Mars. Plus, ‘Oumuamua, Bennu, Ryugu, winds on Jupiter and a space jellyfish.
New research shows that most of the water once thought to have escaped Mars is actually still trapped in the minerals in the crust. And life may still be present and accessible on the red planet. Plus, a cosmic lens, Bennu, volcanoes, more news from LPSC 2021, and our weekly What’s Up.
Monday was the first day of the Lunar and Planetary Science Conference, and we are going to spend at least the next two weeks sharing as much science as possible. The conference is taking place virtually this year, and of course, Mars is the big focus. Plus icy worlds, volcanic worlds, and exoplanets, and we’re bringing you a little of everything.
Climate change is a leading problem in today’s society, and today we have a quartet of stories on its effect on the world around us. Plus, more coverage from the AAS meeting with three stories on black holes, as well as dating supernovae, breaking a star, and magnetic chaos in a galaxy.
Multiple international teams determine that a 2020 gamma-ray burst was actually a giant flare from a magnetar and that flare originated from a nearby galaxy. Plus, the Dark Energy Spectroscopic Instrument is ready for a new survey, NASA extends two planetary missions, and What’s Up in the night sky this next week.
Researchers using NASA’s TESS and the Keck Observatory found a rocky planet orbiting a 10-billion-year-old star in the Milky Way, up in the galaxy’s thick disk. Plus more planetary news from the AAS Winter Meeting, a magnetar, colliding galaxies, and gravitational wave news.
