New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.

Located 50 light-years from Earth, the beady-eyed exoplanet LHS 1140 b could be a perfect candidate for discovering liquid water outside the solar system, new research suggests.

New NASA images of a mountain-size, "planet killer" asteroid that made its closest approach to Earth last month have revealed a surprise companion circling the massive space rock.

New photos of the recently discovered asteroid 2024 MK, which zoomed past Earth in late June, reveal that the massive space rock's orbit has been significantly altered by its close approach to our planet.

Even three days in space is enough to alter an astronaut's biology, according to a new set of studies that offers the most comprehensive look at spaceflight health since NASA's Twins Study.

The James Webb Space Telescope revealed that the hot Jupiter exoplanet HD 189733 b, located just 64 light-years from Earth, has an atmosphere full of hydrogen sulfide, meaning it likely smells of rotten eggs.

Seen for the first time from the ground, the polar rain aurora produced an eerie green glow captured on camera in Norway.

Slovakian artist Martin Vargic's spectacular new infographics artistically portray, visualize and compare more than 1,600 planets in other star systems.

NASA's GOLD mission found unexpected X- and C-shaped structures in the plasma of Earth's ionosphere. Researchers have likened our upper atmosphere to "alphabet soup."

The James Webb Space Telescope found "tiny red dots" in the early universe representing overgrown supermassive black holes and stars that are impossibly old for the infant cosmos.
