Orion isn’t just a few stars in a row, it’s a whole landscape in space. This 212-hour exposure reveals glowing nebulae, arcing filaments like Barnard’s Loop, and stars like Betelgeuse and Rigel. The belt? Still there, if you can find it. Image credit: Stanislav Volskiy 🔭 #Astronomy #Space #NASA

Cathedral to stars. Pismis 24-1 was thought to exceed 200 solar masses, but Hubble revealed it's three stars. Even so, each nears 100 solar masses, still among the heaviest known. Below, new stars form in NGC 6357's glowing cocoon. Credit: #NASA, #ESA, Jesús Maíz Apellániz 🔭 #Astronomy #Space

The Pacman Nebula isn't devouring stars, it’s making them. In NGC 281, young, massive stars carve out dusty columns while their radiation sculpts Bok globules. If they last, these dark knots could birth new stars. Image credit: Juan Montilla 🔭 #Astronomy #Space

This was once a beach on ancient Mars. Curiosity captured this panorama at Ogunquit Beach, Gale Crater. Evidence suggests the area was once underwater or at a lake’s edge. The light bedrock likely formed from settled sediment. Credit: #NASA, JPL-Caltech, MSSS, #CuriosityRover 🔭 🧪 #Space #Astronomy

Saturn's rings are exactly aligned with Earth today, making them "vanish" because they are so thin. Unfortunately the planet is currently hidden in the glare of the Sun, but Alan Friedman compiled a great image sequence of a similar vanishing in 2009. 🧪🔭 avertedimagination.com/img_pages/6_...

The Leo Trio - NGC 3628, M66, and M65 - rises in early evening skies around the March equinox. Though all spirals, they each look different due to orientation. This stunning 1° view spans 500,000+ light-years, captured from Qatar. Image credit: Rabeea Alkuwari 🔭 #Astronomy #Space #NASA

By the way - here are instructions for posting to the new #astrosci feed. The Bluesky UI changed recently and you now have to click the top of the feed to see instructions, which is harder to find. (hoping to improve the pinned post system soon to address this)
