The "cooling-flow problem" in galaxy clusters involves a discrepancy between the predicted rapid cooling of hot gas leading to intense star formation in central galaxies and the observed lack thereof ...

Understanding the early universe is a foundational goal in space science. We're driven to understand nature and how it evolved from a super-heated plasma after the Big Bang to the structured cosmos we ...

Astronomers have gained insights into star formation by capturing the first spatially resolved detection of protostellar ...

The James Webb telescope has imaged one of the more dramatic stellar nurseries in the galaxy called Pismis 24.

The size of our universe and the bodies within it is incomprehensible to us lowly humans. The sun has a mass that is more than 330,000 times that of our Earth, and yet there are stars in the universe ...

NGC 3603-A1 is a pair of giant stars locked in a rapid 3.8-day orbit. Their dynamic relationship provides clues to how ...

This star factory is the largest and brightest in its host galaxy. Recently, the Hubble Space Telescope caught this stunning image of the Tarantula nebula, the largest and brightest stellar factory in ...

A strange flash of light from near the beginning of the universe could help astronomers map difficult-to-see gas in between galaxies, like a flashbulb in a dark room. Fast radio bursts (FRBs) are ...
