Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

For many of us, the idea of a solar system with just eight planets is a fundamental concept in science. However, since Pluto was reclassified as a dwarf planet in 2006, Neptune has stood as the last ...

Dark dwarfs, a theoretical subclass of brown dwarf stars believed to contain dark matter, may be the optimal objects in which to finally discover physical dark matter in the real world—potentially ...

That means returning from the moon, the Artemis astronauts will be traveling at around 0.0037% the speed of light. Assuming a ...

New simulations suggest that dozens of ultra-faint “ghost” galaxies may be orbiting the Milky Way, hidden from current ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, ...

“Dark matter interacts gravitationally, so it could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and annihilate, releasing energy that heats the ...

Modern space exploration relies heavily on resupplies of food from Earth, but this tends to be largely pre-prepared meals that rarely contain fresh ingredients.

The diagram said what words couldn’t: this wasn’t just a company, it was a stranglehold on the economy. In 1911, the US ...

In a bold step toward sustainable space travel, scientists are engineering a radically small, protein-rich rice that can grow ...

A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of ...
