Black Holes Formed Before Stars

Black Holes Formed Before Stars

An illustration of a magnetic field generated by a supermassive black hole in the early universe, showing turbulent plasma outflows that help turn nearby gas clouds into stars. New findings suggest this process might be responsible for accelerated star formation in...

Unexpected Galaxy Photobombs Cluster

A color-composite image of PEARLSDG made with JWST NIRCAM data. Individual stars are visible as small points of light in the image. Its somewhat dull color and lack of many bright stars is consistent with its old age and lack of ongoing star formation. Credit: Image...

Quasars Spotted Blowing Away Gas

Artist’s impression of an outflow of molecular gas from the quasar J2054-0005. Credit: ALMA (ESO/NAOJ/NRAO) Gas dynamics are more than a little complicated no matter where you look. The dynamics of gas in and around forming galaxies makes is particularly...

Explaining Early Bright Galaxies

A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold dark matter theories are correct, the Webb telescope should find tiny,...
