The Space Doctor on Instagram: "The creator and the destroyer. The Andromeda and Milky Way galaxies are expected to collide in about 4.5 billion years. Surprisingly the sun becomes a red giant in around the same time. So what's a red giant? When a star is about to die it increases in size, our sun will do the same. This happens before the Andromeda collides with our milky way to form Milkromeda. Is it a kind of backstab done by sun? Or something else. #space"

Museum of Science on Instagram: "Heads up, skywatchers: the Taurid Meteor Shower is active now through December 10! 🔭 With peak nights on November 4–5 and 11–12, this year could bring a rare “fireball swarm”. These would be extra-bright meteors from two overlapping streams, the Northern and Southern Taurids. Just look up from dark skies, and you could catch dazzling fireballs lighting up the night. #Taurids #MeteorShower #Astronomy #SkyWatch #Space"
