Similar deep-sea volcanoes found on Earth support microbial life that lives inside solid rock without sunlight and oxygen.

A NASA-funded telescope in Chile identified a comet from interstellar space on July 1, marking a significant astronomical discovery. The ATLAS (Asteroid Terrestrial-impact Last Alert System) survey ...

Astronomers have confirmed that a rare intersteller object is zooming through the solar system. This is only the third time this has been recorded.

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new simulations show.

There’s a giant ball of ice barreling through the solar system right now, and it’s bigger than any we’ve seen before. It poses no threat to Earth, but this comet, called C/2014 UN271 ...

A nearby star drifts into the outskirts of our solar system. Its gravity disturbs the Oort Cloud and alters the orbits of far-out objects.

A recent study indicates a small chance that Earth could be ejected from our solar system due to passing stars. Simulations suggest these stellar encounters might disrupt planetary orbits ...

The Last Time NASA's Voyager "Looked Back" At Our Solar System, This Is What It Saw Before it met the 30,000-50,000 kelvin wall at the edge of our Solar System, Voyager 1 took its final images.

This new dwarf planet may exist at the edge of the solar system, possibly disproving Planet Nine's existence. This is the story of that newly encountered planet.

Discover interesting facts about the sun, the solar system's central star that supports all life on Earth.

Researchers from the UW and Queen’s University Belfast believe that knowledge of the objects in the solar system will expand exponentially when a new telescope comes online later this year ...

A computer simulation predicts that the Rubin Observatory will discover millions of previously undetected objects in the solar system.
