Hubble captures 25-year evolution of the Crab Nebula
TL;DR Summary
Astronomers compared two high-resolution Hubble images of the Crab Nebula taken in 1999/2000 and 2024, finding the iconic supernova remnant has expanded and changed shape over 25 years. The nebula’s filaments are moving outward at about 3.4 million mph, driven by energy from the central pulsar rather than a passing shock wave, and the new view reveals 3D structure and varying gas temperatures within the expanding shell.
