However, the USTC researchers have revealed that dark matter halos hosting dwarf galaxies also exhibit halo bias, which is ...

The galaxy appears to have no dark matter—a new, puzzling piece of evidence for astrophysicists to ponder. We have no idea what dark matter really is, and ‘dark’ might not be the best way to ...

Normally, not all of a galaxy’s mass is visible. In addition to a mix of ordinary matter—like stars and planets and manatees—galaxies are expected to contain dark matter, an invisible ...

A research team led by Prof. Wang Huiyuan from the University of Science and Technology of China (USTC) has made a ...

Astronomers experienced that unusual horror when they recently observed the distant galaxy NGC 1277 and found it entirely devoid of dark matter. The stuff has, apparently, vanished into the ...

This dark matter detection method would hinge on two of these vast groupings of galaxies meeting and smashing into each other. As these galaxy clusters are packed with dark matter, astronomers ...

They're laying the blame on a football-shaped, tilted halo of dark matter that envelopes our galaxy. The common image of our galaxy resembles a flattened disk similar to a vinyl record ...

This was the birth of our modern universe of galaxies, so poetically celebrated in Seeing in the Dark. Today, astronomers have measured the distance to the Andromeda Galaxy much more precisely ...
