The Milky Way is warped, possibly as the result of a collision with another galaxy billions of years ago. Studying this warp could reveal more about the structure of our galaxy's hidden matter.

New photos from the James Webb Space Telescope show off the bewitching beauty of the warped quasar RX J1131-1231, which is adorned with four bright spots birthed by mind-bending space-time trickery.

Four volunteers exited a mock Mars habitat at NASA's Johnson Space Center on July 6, bringing the agency's first year-long simulated Red Planet mission to an end.

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.

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.
