The quasi-periodic eruptions of X-rays from a black hole 300 million light-years away are unlike any researchers have ever seen before.

Scientists thought they saw a distant star swallow a planet for the first time ever. But new observations from the James Webb Space Telescope suggest something very different, but equally rare, may have happened instead.

Photos show that comet C/2025 F2 (SWAN) experienced a "major eruption," causing it to become temporarily brighter. However, it's still unclear whether the icy object is a true "cryovolcano."

The most distant and earliest "dead" massive galaxy ever seen shows some galaxies lived fast and died young shortly after the Big Bang.

"What surprised us, at the end, was how effective this type of impact could be in explaining Mercury's unusual structure without needing to consider multiple collisions or extremely rare conditions."

An analysis of star movements from the Gaia spacecraft reveals that the Small Magellanic Cloud — a satellite galaxy bound to the Milky Way — is being torn apart by its larger neighbor.

A pair of white dwarfs, located just 150 light-years from Earth, appears doomed to die in a type 1a supernova that will shine brighter than anything currently visible in the night sky. But humanity — and our planet — will be long gone before this happens.

Also known as the 'Paschal Moon,' April's full 'Pink Moon' will rise alongside Spica, one of the brightest stars in the night sky, on April 12.

The once-dubbed "city-killer" asteroid 2024 YR4 has surprised scientists with its 'unusual' shape as it rapidly rotates through space on a trajectory that could see it hit the moon.
