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 ...

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 ...

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

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with ...

Astronomers believe the two galaxies may collide in next 10 billion years Theory based on data from Hubble Space Telescope and Gaia star-tracking mission 'In short, the probability went from ...

For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has become ...

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 ...

NASA has released a new composite image of two spiral galaxies, NGC 2207 and IC 2163, as they begin a multi-billion-year process of merging into a single celestial entity. This event was captured with ...

Observations using ALMA and JWST show multiple mechanisms fueling starbursts in massive early galaxies, indicating diverse formation pathways during the early Universe.

Mizzou scientists using NASA’s James Webb Space Telescope found unusual "platypus galaxies" that could change what we know ...

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 ...
