For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A ...

Ultrafine dark matter, millions of times lighter than electrons, could flow through the cosmos in waves. We might just have an easy way to check for tiny interactions between this dark matter and the ...

Xenon is a colorless and odorless noble gas that is found in tiny amounts throughout our atmosphere. Despite the little we know about it; scientists have never managed to observe the radioactive decay ...

Using NASA's Fermi telescope, researchers have detected powerful gamma–ray radiation emerging from a 'halo–like' structure surrounding the Milky Way. Its frequency and intensity suggest that this ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

When two enormous clusters of galaxies collided billions of years ago, their dark matter shot right out of them, leaving behind the gas and stars that made up the remains of the clusters.

Even though it’s impossible to see it, dark matter fills the universe. And now, it seems increasingly likely it always has. An international team from Japan used the Subaru Telescope at the ...

Scientists at Nagoya University in Japan claim to have discovered dark matter that dates back 12 billion years ago, which would make it the earliest observation of the hypothetical substance to date.
