Galaxies

The Milky Way's system of small, orbiting satellite galaxies is quite unusual, a new 12-year study of other galaxies in the local universe has found.

A 13-year survey conducted by the VISTA telescope has resulted in the creation of the most detailed Milky Way map ever. It contains a stunning 1.5 billion objects.

A galaxy is robbed of its gas and stars in a new image from the European Southern Observatory.

Machine learning algorithms analyzed millions of galaxies to reveal where the biggest ones are.

Located about 3 million light-years from Earth, the Tucana Dwarf galaxy sits at the far edge of the Local Group of galaxies and is home to aging stars that may hold clues from the early universe.

A new simulation suggests the possible head-on collision of our Milky Way galaxy with the neighboring Andromeda galaxy comes down to a coin flip.

Located at the confluence of several dark matter filaments in the cosmic web, the Coma Cluster of galaxies is the perfect case study for understanding how these galactic conurbations grow.

The European Space Agency has launched a new citizen science project with Galaxy Zoo to classify tens of thousands of galaxies imaged by the Euclid space telescope.

Researchers using the Gaia space telescope studied some ancient stars near the sun, revealing that our corner of the Milky Way may be billions of years older than once thought.

The Euclid and XMM-Newton missions have combined to show the hidden, hot gas that fills an immense galaxy cluster 2.7 billion light-years away.
