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.
Discovered in May 2025 by ATLAS, Comet C/2025 K1 (ATLAS) was photographed by the Gemini North telescope breaking apart as it emerged from behind the Sun in Oct 2025. By early November its nucleus had fragmented into at least three pieces, a fate not uncommon for sun‑baked comets. The event, part of Live Science’s Space Photo of the Week coverage, underscores the volatile survival of comets near perihelion and foreshadows another sungrazer, 3I/ATLAS MAPS, potentially facing a similar solar encounter.
