For decades, black holes have been the ultimate cosmic cliffhanger: regions of space where gravity wins so completely that ...

A balloon-borne telescope has captured one of the most precise glimpses yet of the chaotic environment around a black hole.

If, for some reason, we as a society executed villains by firing them into the Sun, this is how an astronomers says we would ...

First up, just pointing a rocket at the Sun and blasting as hard as you can would result in a wild miss. The main problem you ...

Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

Pluto imparted a slight but measurable alteration to the New Horizons spacecraft's trajectory (both bending and acceleration) during its 2015 flyby. The minimal nature of this trajectory change was ...

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

ABSTRACT: Since the discovery of the Hubble tension and the Sigma 8 tension, the scientific world is still puzzling over the possible causes. We have noticed an inhomogeneous nature of the ...
