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

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 ...

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 ...

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 ...

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 ...

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

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 ...

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 ...

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 ...

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 ...
