Astronomers from the University of Arizona have uncovered astonishing details about a galaxy that existed when the universe ...

By looking ever further back in time, the James Webb Space Telescope is at last revealing the first galaxies – and a very strange young cosmos ...

The new galaxy is of the grand-design subtype and was identified at a redshift of 4.03. "In this paper, we present the discovery, in the Abell 2744 cluster field, of a two-armed, grand-design ...

A "classification" is when a volunteer or citizen scientist finishes marking up or sorting one image or other piece of data.

"They're so rare, and they're incredibly useful scientifically," said Conor O'Riordan of the Max Planck Institute for Astrophysics.

But mapping the galaxy's structure is just one part of the story. Astronomers can also learn about the Milky Way's rotation by studying the redshift and blueshift of the 21 cm radiation.
