NASA's Webb to unveil the secrets of nearby dwarf galaxies

In two separate studies using NASA's upcoming James Webb Space Telescope, a team of astronomers will observe dwarf galaxy companions to the Milky Way and the nearby Andromeda galaxy. Studying these small companions will help ...

Image: Hubble views a not-so-lonely galaxy

Galaxies may seem lonely, floating alone in the vast, inky blackness of the sparsely populated cosmos—but looks can be deceiving. This image of NGC 1706, taken by the NASA/ESA Hubble Space Telescope, is a good example of ...

The violent history of the big galaxy next door

Astronomers have pieced together the cannibalistic past of our neighbouring large galaxy Andromeda, which has now set its sights on the Milky Way as its next main course.   

Hubble takes closer look at not-so-'dead' neighbor

Many of the best-loved galaxies in the cosmos are remarkably large, close, massive, bright, or beautiful, often with an unusual or intriguing structure or history. However, it takes all kinds to make a universe—as demonstrated ...

The galaxy cluster Abell 959

Most galaxies lie in clusters containing from a few to thousands of objects. Our Milky Way, for example, belongs to the Local Group, a cluster of about fifty galaxies whose other large member is the Andromeda galaxy about ...

Spotting merging galaxies

Over 30 years ago, the Infrared Astronomy Satellite discovered that the universe contained many extremely luminous galaxies, some more than a thousand times brighter than our own Milky Way, but which are practically invisible ...

Hubble's dazzling display of two colliding galaxies

Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies. They were first discovered in 1784 by William Herschel and were originally classified as a single irregular ...

First evidence of gigantic remains from star explosions

Astrophysicists have found the first ever evidence of gigantic remains being formed from repeated explosions on the surface of a dead star in the Andromeda Galaxy, 2.5 million light years from Earth. The remains or "super-remnant" ...
