Black Holes Merge: A Historic Spacetime Event

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

Galaxies on Instagram: "On a clear, dark night with no light pollution, the human eye can see about 2,500 to 3,000 stars at once from any one location on Earth. That’s out of roughly 5,000 to 6,000 visible to the naked eye total (since half the sky is below the horizon). If you use binoculars or a telescope, that number jumps into the hundreds of thousands to millions, depending on the equipment and conditions. But with just your eyes, around 3,000 max is what you’ll see under perfect skies."

Jose Huaylinos on Instagram: "This October 2025, the night sky is putting on a spectacular show that you won’t want to miss. From seeing another galaxy to a brilliant supermoon and a meteor shower, there are so many reasons to look up."
