Astronomer Pieter van Dokkum and colleagues wanted to know more about how these huge, star sparse structures worked, but detailed observations of this galaxy recently published in Nature were odd.

This Galaxy Has Almost No Dark Matter—and Scientists Are Baffled. If astronomers really have found an "undark" galaxy, it’s a strong clue that dark matter is real.

A galaxy that has these narrowly peaked spectral lines could be devoid of dark matter if it were at the originally inferred distance of ~64 million light-years, but could exhibit the same spectral ...

The galaxy NGC 1277, located roughly 240 million light-years from here, has several times the mass of the Milky Way and should be comprised of between 10% and 70% dark matter.

For example, in 2016, a study detailed the discovery of a galaxy made almost entirely of dark matter. (Think of it as the Bruce Willis to NGC 1052–DF2's Samuel L. Jackson in Unbreakable .) That ...

Astronomers have created the most detailed view yet of the Sculptor Galaxy, a nearby active spiral galaxy characterized by intense star formation and intricate structures. Using the European ...

To dark matter and dark energy, add dark galaxies — collections of stars so sparse and faint that they are all but invisible. An artist’s depiction of hydrogen gas observed in the galaxy J0613 ...

An invisible halo of misaligned dark matter could explain the warps at the Milky Way's edges. A gigantic blob of invisible dark matter has bent our galaxy out of shape, a new study suggests ...

The remarkable thing is that the central bright region of the Andromeda Galaxy can—when it's really dark, and you know just where to look—be glimpsed with the naked eye.

What caused the dark matter around our galaxy to fall out of tilt isn't clear, but the researchers' simulations suggest it is likely to have been a gigantic collision, ...

Astronomers using NASA’s Hubble Space Telescope took advantage of a giant cosmic magnifying glass to create one of the sharpest and most detailed maps of dark matter in the universe.
