'The early universe is nothing like we expected': James Webb telescope reveals 'new understanding' of how galaxies formed at cosmic dawnAstronomers using the James Webb Space Telescope have observed five extremely dense proto-globular clusters along a hair-thin arc of glittering stars. The discovery could help them understand how the earliest galaxies formed.

'Immortal' stars at the Milky Way's center may have found an endless energy source, study suggestsStrange stars clustered near the Milky Way's center are much younger than theory predicts is possible. New research suggests their youth could actually be eternal — and fueled by annihilating dark matter.
