Rare, elliptical craters spotted on two of Saturn's moons reveal new clues about the satellites' age and formation, a new study shows. Using data from NASA's Cassini mission, researchers from the ...

Hubble's new image of the Sombrero Galaxy, Messier 104. ESA/Hubble & NASA, K. Noll. Messier 104 was discovered back in 1781 by the French astronomer Pierre Méchain—and has since been the ...

When NASA's Hubble Space Telescope snapped a picture of an elliptical galaxy, it caught something else in the frame: A bright, red arc of light wrapped around it.. That glowing curve isn't the ...

It has a smooth-looking, armless shape, like an elliptical galaxy, and a disk with a low star-formation rate. However, it has relatively younger and newer stars forming in its central region.

Galaxy Arp 184, however, we are seeing from an angle, so it looks different. More than that, though, Arp 184 is skewed so that it isn’t perfectly spiral shaped.

A Hubble image captures a distant galaxy, HerS 020941.1+001557, whose light is magnified and bent by a foreground elliptical galaxy, SDSS J020941.27+001558.4, forming a partial Einstein ring.

The Milky Way sits within a galaxy cluster on the Supergalactic Plane — a billion light-year-wide sheet, or "supercluster," upon which large galaxy clusters are pinned. But other spiral galaxies ...
