A century ago, humans didn't know other galaxies existed. Here's how Edwin Hubble changed that view.

2024 was a big year for the study of the universe's most troubling and mysterious "ingredient," dark energy. Here's what scientists found.

Scientists theorize there could be subatomic particles we have yet to discover. Here are five of the weirdest, rarest hypothetical particles in the universe.

A new frontier has been reached in simulations of the universe, with the powerful exascale supercomputer called "Frontier" performing the most detailed simulation yet of the cosmos.

A new study suggests galaxies in the early universe appear much larger and brighter than expected, precisely as predicted by modified Newtonian dynamics, or MOND.

The "first page" of an incredible cosmic atlas being built by the Euclid Space Telescope has been released. The millions of stars and galaxies represent just 1% of the 3D map the mission will create.

Astronomers have discovered the most distant and, thus, earliest strongly rotating galaxy ever seen that is well-organized rather than chaotic and messy, challenging our theories of cosmic evolution.

New observations from the MeerKAT radio survey suggest our estimates of the cosmic dipole effect are actually in line with the large scale structure of the universe.

NASA's New Horizons spacecraft, which flew by Pluto in 2015, has offered the best-yet estimates of how dark deep space truly is.

Every so often, astronomers detect a supernova explosion that's 100 times brighter than it should be. A new paper may reveal the strange source of these "superluminous" supernovas.
