The SPHEREX mission will create multiple surveys of the near-infrared sky that will reveal the origins of life and perhaps the universe itself.
By tracing stars in other galaxies, the Gaia satellite has helped astronomers understand the relative motions of the Milky Way's galactic siblings.
Starbirth and stardeath light up a nearby galaxy while faraway galaxies twist and bend in these new images from NASA's Hubble and Chandra space observatories.
A new study says our neighbor galaxy’s big stellar halo and stellar evolution are due to a major collision that ended 2 billion years ago.
The Magellanic Clouds — two nearby dwarf galaxies easily visible to the naked eye in the southern hemisphere — are key to understanding the dynamics and evolution of the Local Group of galaxies. Can an in-depth look at these galaxies’ outer regions help us make sense of their complicated interaction history?
At least 14 galaxies are swarming in the early universe, forming a protocluster with the mass of 10 trillion Suns. It might become one of the most massive structures in the universe.
You may have seen recent news about NGC 1052–DF2, a galaxy that was discovered to have little or no dark matter. Now, a new study explores what NGC 1052–DF2 does have: an enigmatic population of unusually large and luminous globular clusters.
Most of the dwarf galaxies around Centaurus A appear to be orbiting the giant galaxy along a single plane — a result not predicted by current cosmological models.
