Using substantial ground arrays and underground muon detectors, the Tibet ASγ Collaboration has captured evidence of ultra-high-energy gamma rays that are thought to be the result of nuclear interactions between cosmic rays and interstellar gas. Plus, OSIRIS-REx, Ingenuity, InSight, comet 2I/Borisov, and things getting hit (or not) by other things.
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.
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.
A new study examines the formation of rocky worlds from dust particles containing ice and carbon, increasing the possibility that our own Milky Way galaxy could be filled with aquatic planets similar to Earth. Plus, a simulation of the Milky Way-Andromeda collision and an overview of asteroid Apophis.
A new super-Earth has been discovered that has an extremely hot surface temperature, and this planet could be a boon for studying the atmospheres of rocky exoplanets. Plus, our daily news roundup, climate change, and how a petrified tree on Earth might help us hunt for fossils on Mars.
Join us for this week’s Rocket Roundup with host Annie Wilson as we look back at the launches that happened over the last week, including international launches from China, India, and Russia. Plus, we look back at Beresheet, the ill-fated lander that launched on February 22, 2019.
Get your daily dose of all that’s new in space and astronomy. The sky is not the limit, as we bring you a fast-paced roundup of launches, landings, and everyday discoveries.
