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"

Samil Cabrera on Instagram: "Tonight’s full Harvest Supermoon  This moon is the first of three back-to-back supermoons this year. A supermoon happens when the moon reaches perigee, or its nearest point to our planet, making it appear larger and fuller. I captured this image at 11:00 p.m. ET, when the Moon was 100% illuminated from my location. #harvestmoon #supermoon #fullmoon #stars #space #viralreel #sonyalpha"

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"

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

Cleo Abram on Instagram: "Our solar system is on a collision course. Yep. Here’s what you need to know… These visuals are from the American Museum of Natural History’s incredible show, Encounters in the Milky Way. It’s incredible. Go watch it! #history #sky #space #timelapse #animation"
