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.

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.
Millions of light-years from Earth, there’s a galaxy that is completely devoid of dark matter — the mysterious, unseen material that is thought to permeate the Universe.
Using the Hubble Space Telescope and a cosmic magnifying glass effect, astronomers have put together one of the most detailed maps yet of dark matter in a giant galaxy cluster. Dark matter is the ...
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.
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.
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 ...
"In a galaxy, you have 100 billion stars, all pulling on each other, not to mention other components we don't see like dark matter," said Caltech's Phil Hopkins, associate professor of theoretical ...
The light bent by a dark-matter-dominated galaxy can form what is known as an "Einstein ring" Astronomers have spotted a "dwarf" galaxy some 10 billion light-years away which may be made mostly of ...
Dark matter is not behaving as we would expected it to, scientists have said. There is an unusual mismatch between our theoretical models of how dark matter should be spread across galaxy clusters ...
