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

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

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 ...

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 ...

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 ...

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 ...

CAPE CANAVERAL, Fla. — It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral ...

The pseudo-color images of JWST’s Quintet at redshift 6.71. a) The pseudocolor image created from NIRCam F115W (blue), F150W (green), and F200W (red) images. The five emission line galaxies in JWST’s ...
