New cosmology studies suggest the universe may not be perfectly uniform, potentially challenging long-standing assumptions ...

"The Story of Everything" documentary argues scientific discoveries about the universe, DNA and fine-tuning point to the existence of a creator God.

The conclusion of DESI's first survey marks an important milestone for cosmology, which finds itself in a bind for the best reasons.

Cyclic cosmology, or the big bounce, is the idea that the universe will eventually crunch back together and then go through another big bang. Columnist Leah Crane finds that, appropriately, it’s comin ...

This sketch is of the cosmic microwave background timeline of the universe in the Lambda Cold Dark Matter model. The accelerated expansion shown in the last third of the timeline represents the dark ...

Recent surveys hint that the rate of cosmic expansion changes dramatically over time; if that's true, then the universe could end much sooner than we thought, new research suggests.
