A panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away, requiring over 600 Hubble overlapping snapshots to stitch together.

Hubble's sharp imaging capabilities can resolve more than 200 million stars in the Andromeda galaxy, detecting only stars brighter than our Sun. They look like grains of sand across the beach.

In a landmark study, scientists using NASA’s Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large galactic neighbor.

Galactic neighbor: NASA's Hubble Space Telescope has captured a massive panoramic view of the neighboring Andromeda galaxy (Messier 31), which is situated just over 2.5 million light-years away ...

The impending merger of the two galaxies hints at what might be in store for the Milky Way and the Andromeda galaxy if and ...

The Hubble Space Telescope has finally completed a stunning mosaic of the Milky Way's closest cosmic companion, the Andromeda Galaxy — having spent more than a decade snapping the spectacular image.

Messier 31 is located 2.5 million light-years away from Earth and was a much bigger target in the sky than the galaxies Hubble routinely observes. The post Stunning new panorama of Andromeda ...

Hubble was in the process of gleaning clues about dark matter. New images released by NASA's Hubble Space Telescope are of the Pegasus Dwarf spheroidal galaxy, also known as Andromeda VI. Pegasus ...

The Andromeda Galaxy, the Milky Way's closest galactic neighbor, glows brightly in a new Hubble Space Telescope image with swathes of ionized gas that fuel star formation.

Hubble gazes at galaxies all the time—the famous Hubble Deep Field images alone show countless galaxies in faraway parts of the universe. Andromeda, however, is much closer and takes up more of ...

Before then, the orthodox cosmological view was that the Milky Way encompassed the entire known universe, and that Andromeda had to be part of it as a result. Hubble's estimate that M31 was 2.5 ...

Scientists using NASA’s Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and ...
