Full view of the newly discovered Nereides supernova remnant G107.7-5.1. [Fesen et al. 2024]
The images above and to the right show the delicate gaseous filaments of a newly discovered supernova remnant, the Nereides Nebula. Over the past two years, a team led by Robert Fesen (Dartmouth College) has studied supernova remnants from 10 observing sites across Europe, Africa, New Zealand, and the US. Through the course of this campaign, the team racked up more than 1,000 hours of exposure time and produced more than 12,000 images, greatly improving the quality of data available for nine known Milky Way supernova remnants — and they discovered three more supernova remnants along the way. The new images demonstrate the immense size and intricate tracery of these exploded stars, and in some cases, reveal never-before-seen emission structures. It was a challenge to pick just a single image to appear in today’s post — be sure to check out the article linked below to see all of the new images!
