What's behind the Martian methane mystery?
The brief spikes of methane observed on Mars tend to follow the seasons, with late spring and early summer seeming to have the highest levels of atmospheric methane.
James Webb Space Telescope uncovers secret supermassive black holes that escape traditional detection
New research reveals how quiet galactic engines can help shape entire galaxies.
What happens when black holes merge?
When black holes merge, what happens inside of them is anybody's guess.
Supercharged 'cocoon of energy' may power the brightest supernovas in the universe
Every so often, astronomers detect a supernova explosion that's 100 times brighter than it should be. A new paper may reveal the strange source of these "superluminous" supernovas.
A long-lost moon could explain Mars' weird shape and extreme terrain
Unlike the other planets in the solar system, Mars is distinctly triaxial, meaning it is an ellipsoid with different sizes along all three axes.
How did Earth get such a strange moon? Exploring the giant impact theory
Surprisingly enough, the moon is a piece of our planet.
Why were galaxies so active in the early universe? We may be getting close to the answer
This strange shift in the cosmos’ early disposition is a crucial clue to how the very first galaxies burst into being, shaping everything we see today.
Ultralight dark matter may have helped monstrous black holes form in the early universe
It could explain how these giant black holes formed before even the first stars.
How do particle colliders work?
As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing them into tiny targets.
