Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar ...

New measurements confirm the universe expands faster than predicted, reinforcing the Hubble tension and challenging the standard model of cosmology.

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

The largest 3D map of the universe reveals over 47 million galaxies, but dark energy remains an unsolved mystery.

The finding was discovered by Rajendra Gupta, a physics professor at the University of Ottawa, who has proposed a model that aims to explain the universe without dark matter or dark energy.

The Dark Energy Spectroscopic Instrument, or DESI, has finished its planned 3D map of the universe — but the work is far from over. Carnegie Mellon University researchers are already pushing the ...

If our galaxy was in the middle of the Boötes void, we wouldn’t have known there were other galaxies until the 1960s.

Astronomers detect the most powerful space laser from colliding galaxies 8 billion light-years away, offering rare insights into the early universe and cosmic signals.

Cosmologists have spent decades trying to pin down exactly how fast the universe is flying apart and whether that rate is ...

Scientists have mapped the extent of the Vela Supercluster for the first time, and determined that it is one of the largest ...
