Galaxy merger is a crucial process in galactic evolution that has happened since the first galaxies came into being. Now JWST ...

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

Using observations from the James Webb Space Telescope (JWST), the researchers identified an ongoing merger event of at least ...

A new simulation tool lets scientists explore whether self-interacting dark matter could reshape galaxies from the inside out ...

Whoooooo's there? Just a "Cosmic Owl," the latest strange discovery from the James Webb Space Telescope (JWST). A new study using JWST data has helped scientists spot an owl-faced object peering out ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

In this combination of images from NASA/ESA shows three future scenarios for Milky Way & Andromeda encounter. Top left: Galaxies bypass at 1 million light-year separation. Top right: At 500,000 ...

Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than ...

Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe. While studying the distant galaxy cluster known as ...

Nearly all stars are found inside or around galaxies, because that's where the conditions are right for stars to form. Within galaxies, stars form inside cold, dense molecular gas clouds like those ...

Some galaxies in the early universe were absolute powerhouses, churning out stars at rates that would dwarf the Milky Way's ...
