It’s a day ending in ‘y’, and planetary formation theories are once again being challenged. This time the challenge comes from a six-planet system with five planets in resonance. Plus a cloudless Jupiter, TRAPPIST-1, volcanoes, and some science of the weird.
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.
Join us today while we talk about the early formation of stars and galaxies in the universe. We find some joy in an astronomer using 25-year old data to prove that Proxima c exists. And we learn about the Kepler-160 system which is very reminiscent of our own Sun-Earth system.
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.
