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 ...

Day 9 of the 2024 Space Telescope Advent Calendar: a dark and dusty galaxy. This Hubble view of NGC 1546, a spiral galaxy about 50 million light-years away, provides good view of dust lanes from ...

With a new set of observations from Hubble, we not only have confirmed that his galaxy indeed has no dark matter, but we can finally fully explain what’s happening. Here’s the scientific story.

If astronomers really have found an "undark" galaxy, it’s a strong clue that dark matter is real.

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.

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.

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 ...

Scientists appear to have found a galaxy devoid of dark matter, a strange and interesting finding.

A fuzzy form of dark matter may clump up to become the cores of galaxies, according to new research.

A galaxy isn't big just because it has many stars in it. A worldwide research group has discovered that a galaxy in the Coma cluster, Dragonfly 44, consists of 99.99 percent dark matter. It has ...

Detailed dark matter map yields clues to galaxy cluster growth The result suggests that galaxy clusters may have formed earlier than expected, before the push of dark energy inhibited their growth.
