The glowing remains of a historic stellar explosion first spotted in 1181 AD: Supernova Remnant Pa 30. ✨
Tropical cyclones need the Coriolis effect to rotate. Near the equator that force is too weak, so storms almost never form there, and none have ever crossed it. 70 years of data make it clear.
Did you know @museband’s “Hexagons” channels one of the solar system’s strangest geometries? Saturn’s massive north polar hexagon, a six-sided jet stream wider than Earth, is the perfect cosmic inspiration.
Solar flares and massive magnetic loops erupting in real time. Proof that the cosmos is as terrifying as it is breathtaking. 🌞🌌
Mark your calendar! Halley’s Comet left us a cosmic souvenir, and the Orionids peak overnight from Oct 21–22, 2026. Look toward Orion after midnight for the best view! ☄️

Created 2 billion years ago by a massive asteroid, it reshaped the land into a giant ring visible from space! 🛸
Is this the most Earth-like world we’ve found so far? 🌍
Journey across the cosmos to KOI-4878.01, a candidate world almost identical in size and orbit to Earth.
