Cause baby, you're a firework ๐ค๐
This is Pa 30, an explosive cloud of gas and dust bursting from a central hot blue star. Astronomers say itโs the likely remnant of a supernova that people on Earth saw in the year 1181. The explosion created the spectacular, firework-like shell we see around the star.
Now, new observations from the Gemini North telescope on Maunakea in Hawaiโi have revealed this supernova remnant in unprecedented detail. They show that the shellโs long, radial filaments are not smooth streaks as previously thought. Instead, they are made up of chains of tiny knots of gas.
The supernova, known as SN 1181, was visible in the sky for 185 days and is one of only five supernovae in the Milky Way recorded before the invention of the telescope.
This image was captured with the Gemini Multi-Object Spectrograph on the Gemini North telescope, one half of the International Gemini Observatory, operated by NSF NOIRLab.
