What: New analyses using early observations from the European Space Agency’s Euclid mission examine how galaxy mergers ...

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

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 ...

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 ...

Four galaxies crowd the center of a collapsing structure 1.4 billion years after the Big Bang. Each one is churning out stars ...

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 ...

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 ...

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 ...

Discover seven unusual galaxies defying scientific predictions, from impossibly bright early universe objects to astrophysics ...

A sheet of dark matter lying beyond the boundary of the Local Group is responsible for this.

NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. Many years ago, scientists saw a dense, bright spot near a ...

A surprising new set of objects in space with mismatched parts has been discovered by University of Missouri astronomers, ...
