In particular, they speculated that some vortex lines might extend beyond a single halo, connecting galaxies through the vast ...

The game-changing Vera C. Rubin Observatory will collect more astronomical data in its first year than all other telescopes ...

Dark matter "lampshades" could slip between Earth and distant stars, causing tiny amounts of dimming that may help explain one of the greatest puzzles in science.

Bernet wondered whether galaxies’ spiral arms might cause a similar reaction in the dark matter halo. Others had theorized about this possibility but hadn’t examined it very closely.

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

All galaxies are made up of stars, gas, dust, and dark matter, which are bound together by gravity. The Bullet Cluster is made up of two very massive collections of galaxies, known as galaxy ...

But it only accounts for about 15% of matter in all of the known universe. The vast majority of matter is dark – invisible until it is detected only through its gravitational effects.

It Might Have Come From Dark Matter. Scientists have never directly detected dark matter, but some wonder if one high-energy detection in 2023 could be a rare indirect glimpse at it.

For this latest study, the researchers explore another dark matter suspect called massive astrophysical compact halo objects, or MACHOs. Unlike other candidates, MACHOs are hypothesized, rather ...
