Atoms are the building blocks of all matter in the universe, but how many are there in the part of it we can see from Earth?

Researchers found evidence of an elusive magneto-rotational hypernova explosion for the first time ever.

Astronomer Wendy Freedman suggests that the latest observations of red giant stars could be closing the gap on the Hubble tension.

Tendrils of galaxies up to hundreds of millions of light-years long may be the largest spinning objects in the universe, a new study finds.

The Dark Energy Survey just released its most comprehensive results. But did they really prove Einstein wrong?

Scientists have recreated the first matter that appeared after the Big Bang in the Large Hadron Collider.

Astronomers try to solve the mystery of antihelium by searching for antistars.

Physicists have long been unable to describe what happened just after the Big Bang when a teensy blip ballooned into the universe, a process called inflation. We may know why.

An ultra-high-resolution simulation of a tiny slice of the universe — a million times smaller than a proton — has revealed the very first structures to ever exist.

Believe it or not, physicists are attempting to understand the universe when it was only a handful of seconds old.
