Latest Andromeda constellation Stories
For over 10 years, NASA's Chandra X-ray Observatory has repeatedly observed the Andromeda Galaxy for a combined total of nearly one million seconds.
Astronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other.
A diverse cast of cosmic characters is showcased in the first survey images NASA released Wednesday from its Wide-field Infrared Survey Explorer, or WISE.
In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet.
Astronomers have reported that the neighboring Andromeda Galaxy appears to have cannibalistic tendencies as it has expanded by â€œdigestingâ€ stars from other nearby galaxies.
As scientists attempt to learn more about how galaxies evolve, an open question has been whether collisions with our dwarf galactic neighbors will one day tear apart the disk of the Milky Way.

Andromeda Galaxy -- The Andromeda Galaxy, also known as M31, or the object 31 on the catalog of Messier, is the other giant spiral galaxy in the Local Group, together with our galaxy, the Milky Way. It is at a distance of approximately 2.36 million light years or 725 kpc, in the direction of the constellation Andromeda, and it will probably merge in the future with our galaxy, to form a giant elliptical. With a mass of about 1.5 times more than the Milky Way, it is the dominant galaxy...
