APOD: 2022 November 29 - The Gum Nebula Supernova Remnant

Good morning, Rallypoint, and welcome to the November 29th edition of Astronomy Picture of the Day (APOD): "The Gum Nebula Supernova Remnant." The Gum Nebula lies across the southern constellations Puppis and Vela, and was first discovered by Australian astronomer Colin Gum in 1955. It is believed to be a supernova remnant, as tell-tale signs of X-ray (from the initial blast wave) and radio (from neutral hydrogen atoms) emissions have been detected. The Gum Nebula also surrounds the Vela Pulsar, which suggests it may be the result of at least two supernova explosions.

This May 2022 photo was taken in the Atacama Desert in Chilé. If you've followed APOD for any period of time, you recognize the Atacama Desert as one of the locations where you would find a telescope belonging to the European Southern Observatory (ESO). If you mouse over the photo from the APOD page, you'll see annotations for the Gum Nebula, Large Magellanic Cloud (LMC), and the Carina Nebula (NGC 3372).
