Explanation: What happens when one of the stars in a binary goes supernova? This image combines visible (yellow), ultraviolet (purple) and infrared light (cyan, red and orange) to show two supernova remnants and their surrounding environment, about 6,000 light-years away. The younger one is the well-known Jellyfish Nebula in the center (mostly in yellow). If we could see it by eye, it would appear larger than the full moon in the sky. The filament shown in purple is part of an older, overlapping supernova remnant, G189.6+3.3. A new study used data from NASA’s Fermi Gamma-ray Space Telescope to piece together their story. Astronomers believe that there were two stars in a binary system, then the first one exploded as a supernova, kicking away its companion, which also exploded as a supernova tens of thousands of years later, creating the superimposed supernova remnants we see today. The bright star on the right is actually a triple star system named Propus.

Edited to add: Since a lot of people are reblogging this original post, I'm adding the updated version I did that incorporates the intersex circle...

Night on a Spooky Planet

Moon Joy June may be over, but Moon Joy never dies! NASA’s Artemis missions represent the future of space exploration. We choose to go to the Moon to inspire a new generation of explorers, to prepare for the first crewed missions to Mars, and to make discoveries for the benefit of all. Thank you for sharing your Moon Joy with us — we feel it, too. If you are interested in feeling even more Moon Joy, check out International Observe the Moon Night coming up on Sept. 19, 2026. You can join a community, attend an event, and meet up with other lunar observers.
