Learn how through a process known as molecular hydrogen cooling, stars may be able to form in dark matter halos under 10 ...

Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark matter ...

The red circle shows a dwarf galaxy like Triangulum II. Although it has a lot of dark matter, it has very few stars. Dark matter-dominated galaxies like Triangulum II are excellent prospects for ...

Every galaxy we can see is believed to sit at the center of a huge cloud of invisible material called a dark matter halo. These halos stretch far beyond the edges of the visible stars and gas in a ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new ultra-faint dwarf galaxy ... most dark matter–dominated, and least chemically ...

"This work highlights Euclid's remarkable ability to detect and characterize dwarf galaxies, enabling a comprehensive view of galaxy formation ... dust and dark matter, to be ejected into space.
