World's largest digital camera observes cosmos, capturing detailed images of galaxies, asteroids, and stars changing ...

Two bright star-forming regions light up the spiral’s edges, one mirroring Ambartsumian’s Knot, the other possibly a ...

One possible channel for the formation of dwarf galaxies involves birth in the tidal tails of interacting galaxies. We report the detection of a bright UV tidal tail and several young tidal dwarf ...

Galaxies that host tidal debris are also systematically bluer than the average galaxy at fixed stellar mass. These findings extend the observed dwarf dwarf merger sequence with a significant sample of ...

More Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take ...

The concept of dwarf galaxies swarming around larger galaxies is expected from models of galaxy formation based on the standard model of cosmology, which depicts a universe filled with what's ...

Looking at a distant galaxy means looking back in time.

Moons are locked in orbit around planets. Planets, asteroids and comets orbit more massive stars, and stars collect around supermassive black holes, forming galaxies. Large galaxies, like the Milky ...

While elliptical galaxies are known for their smooth and featureless appearance, the hot blue stars at the center of IC 3430 are an exception. These young stars are rare in elliptical galaxies.

This other recent Hubble image also shows a dwarf galaxy, one called NGC 5238. This one is located 14.5 million light-years away, but has a different and more complex type of structure.

To celebrate its 25th anniversary, the Gemini North telescope team has released a stunning image of starburst galaxy NGC 4449, which is ablaze with intense star birth as it devours smaller galaxies.

A new galaxy survey, however, fills in these missing pieces to show that many of these enigmatic objects are likely formed from the destruction of dwarf galaxies. Credit: NOIRLab/NSF/AURA/M. Zamani ...
