New James Webb telescope video reveals incredible Cartwheel Galaxy

Fireworks: The James Webb Space Telescope is once again wowing with its view of the universe. It has peered into the chaos of the Cartwheel Galaxy (pictured), revealing new details about star formation and the galaxy's central black hole

Travelling 500 million light-years in just a matter of seconds, this incredible new video zooms through space to reveal the spectacular Cartwheel Galaxy as captured by the James Webb telescope. The $10 billion (£7.4 billion) observatory’s powerful infrared gaze produced a rare sight of the Cartwheel and two smaller companion galaxies against a backdrop of …

New warning that collapse of Antarctica ‘sleeping giant’ could raise sea level more than 16ft

New warning that collapse of Antarctica ‘sleeping giant’ could raise sea level more than 16ft

The collapse of Antarctica’s “sleeping giant” could cause planetary-scale change in the coming centuries, according to a new warning from scientists. If the climate crisis continues on its current trajectory, then melting of the East Antarctic Ice Sheet (EAIS) alone could contribute around 3-10 feet (1-3metres) of sea-level rise by 2300, and 7-16.4ft (2-5m) by …

Smith had been trying to understand properties of solutions to equations called elliptic curves. In doing so, he worked out a specific part of the Cohen-Lenstra heuristics. Not only was it the first major step in cementing those broader conjectures as mathematical fact, but it involved precisely the piece of the class group that Koymans …
