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"

Astro Alexandra on Instagram: "TWO comets in the night sky this week alongside the Orionids meteor shower and the new moon! #space #astronomy #nasa #science"

New Scientist on Instagram: "Don't miss the Orionid meteor shower next week 💫⁠ ⁠ The Orionids meteor shower, peaking on October 21, 2025, is a spectacular celestial event caused by debris from Halley's Comet, offering a chance to see 10 to 20 meteors per hour under ideal conditions. This year the peak of meteor shower coincides with a new moon so it'll be easier to see it streak across the night sky. ⁠ ⁠ Tap the link in bio to learn more ⁠ ⁠ #meteorshower #skywatch #stargaxzing #orionids #space
