NASA's telescopes have captured detailed observations of interstellar object 3I/ATLAS, confirming it as a natural comet rich in CO₂ and water ice. Discovered in 2025, the comet's composition and ...

Scientists from the Southwest Research Institute have found strong evidence that near-Earth asteroids Bennu and Ryugu share a common origin with Polana, a much larger asteroid in the main belt. By ...

Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth's orbit came from. The origin of the differing tilts in the orbits of the ...

Last month, Google quietly killed off Google Sky Maps. But there’s still another way to virtually explore most of the solar system a la Google Maps: it’s called Google Maps in Space. Google Maps in ...

For astrobiologists, the search for life beyond our solar system could be likened to where one would look in a vast desert—essentially, where there's water. And it turns out that one of the most ...
