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

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 ...

New research suggests that the Milky Way may host more satellite galaxies than previously predicted, thanks to advanced ...

Citizen scientists using the Kilonova Seekers platform spotted a stellar flash 2,500 times brighter than before, allowing ...

“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 ...

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 ...

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

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

A dramatic cosmic event, a rare dwarf nova that suddenly brightened by a factor of 2,500, has been discovered with the help ...

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

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.

With the aid of citizen scientists, astronomers have discovered an erupting cataclysmic variable star in a rarely seen ...
