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

Astronomers at Texas A&M University have discovered a rare, tightly packed collision of galaxies in the early universe, suggesting that galaxies were interacting and shaping their surroundings far ...

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

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

Two space telescopes really are better than one. This month NASA released a new image that combines observations from the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory of two ...

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 ...

Dark stars powered by dark matter may explain bright galaxies, massive black holes, and mysterious red objects in the early universe.

A strange line of dwarf galaxies may have been the result of a bullet-like cosmic collision. Michael Keim at Yale University and his colleagues used the Keck Observatory in Hawaii to study a unique ...

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

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 ...
