Astronomers may have detected a dozen large objects lurking beyond the Kuiper Belt at the edge of our solar system, suggesting there could be another equally massive, "second Kuiper Belt" hiding beyond the orbit of Pluto.

New research showing that elusive antimatter falls downward toward the Earth proves Albert Einstein right yet again.

The James Webb Space Telescope has snapped a stunning image of a perfectly formed Einstein ring, which is also the most distant gravitationally lensed object ever detected.

NASA's James Webb Space Telescope has spotted a distant supernova that appears three times in the same photo. The new observations could help solve one of the universe's biggest inconsistencies.

Astronomers have spotted a gigantic void they believe to be a baryon acoustic oscillation — a relic from when the universe was a fiery plasma soup.

Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'

What happens when an invisible star dies? It erupts in an invisible explosion, of course. New research describes how these unseen 'bosenovas' may behave.

Any object with mass distorts the space-time continuum, which we perceive as gravity pulling us "down" toward that object's center.
