Supernovas might be linked to past climate shifts
This is the Vela supernova remnant in the Southern Hemisphere constellation Vela. Some 13,000 years ago, a star exploded as a supernova, leaving behind its dusty remains in the nebula we see here. A new study examined the Vela supernova remnant and others, looking for a link between supernovas and past climate shifts on Earth. Image via CTIO/ NOIRLab/DOE /NSF /AURA. Image Processing: T.A.
