We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after ...

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard ...

A new study questions dark energy's role in the universe's acceleration, suggesting it may be weakening instead.

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...

Studies suggest that the universe's expansion is decelerating — but what could that mean for the future of the cosmos?

So dark matter doesn't absorb, reflect, or emit any light. While dark matter is invisible, it does have some things in common with ordinary matter: It takes up space and it holds mass. Because of this ...

The Roman telescope promises to provide a clearer picture of the large-scale structure of the universe and the forces shaping it, bringing scientists closer to understanding the cosmic puzzles of dark ...

"Dark matter 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 star." When you purchase through ...

Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed ...
