Dark matter could be a cosmic relic from extra dimensions
By Robert Lea published
Massive gravitons may have formed a trillionth of a second after the Big Bang, in abundances great enough to account for dark matter.
![Computer simulations showed large galaxies may steal dark matter from smaller galaxies when they collide. The close-up views reveal two galaxies lacking dark matter, compared to the brighter regions in the image.](https://cdn.mos.cms.futurecdn.net/AtpH6RNz2kCyth4p2x9jGD-320-80.jpeg)
Cosmic robbery could explain lack of dark matter in some galaxies
By Samantha Mathewson published
Large galaxies may steal dark matter from smaller galaxies they nearly collide with, new research suggests.

Shredded 'stellar streams' could lead to the Milky Way's missing dark matter
By Brandon Specktor published
Astronomers mapped 12 stellar streams, which could lead to the Milky Way's missing dark matter.
![The galaxy AGC 114905 seems to be devoid of dark matter. In this image, the stellar emission is shown in blue; and green clouds show the neutral hydrogen gas.](https://cdn.mos.cms.futurecdn.net/k2WMbP7RkyUVX9vwNVoYNb-320-80.jpg)
This faraway galaxy may be completely devoid of dark matter
By Mara Johnson-Groh published
On the surface, a galaxy 250 million light-years from Earth seems like any other, but a deeper look reveals a puzzling quirk: It seems to have no dark matter.

Dark matter may spawn more of itself from ordinary matter, like a cosmic ice-9
By Joanna Thompson published
A new mechanism for dark matter creation could explain the current six-to-one ratio of dark matter to matter.

Astronomers spot dark matter creating eerie clones of a distant galaxy
By Ben Turner published
It took more than eight years for the scientists to explain the bizarre finding.
![Two Hubble images show the galaxy cluster MACS J0138. In the 2016 image, light from the ancient Supernova Requiem appears in three different spots simultaneously on the edge of the cluster (circled in white). In the 2019 image, they are gone.](https://cdn.mos.cms.futurecdn.net/eV28au9mekAmFji8rurQSD-320-80.png)
A 10 billion-year-old supernova will soon replay before our eyes, new dark matter study predicts
By Brandon Specktor published
Scientists predict that an ancient supernova will reappear in the sky for a 4th time in the year 2037, thanks to the meddling influence of dark matter.

Travel through galaxies and the dark matter web in this stunning universe simulation
By Stephanie Pappas published
A new freely downloadable universe simulation reveals the structure of galaxies and galactic clusters over more than 13 billion years of history.
