A massive collision between two asteroid-sized bodies around a nearby star offers a rare look at the violent process of ...

For only the second time ever, a collision between two asteroids has been observed around an alien star not too far beyond ...

Astronomers have repeatedly observed events near a distant star that mirror processes from the early solar system’s ...

In an unprecedented celestial event, NASA's Hubble Space Telescope (HST) captured the dramatic aftermath of colliding space ...

NASA's Hubble Space Telescope and an ESA orbiter bound for Jupiter both recently glimpsed 3I/ATLAS. The comet will make its closest approach to Earth in December but poses no threat and is not visible ...

Hubble Space Telescope data reveal that two large collisions near the star Fomalhaut created dust clouds once mistaken for a planet, helping scientists better understand how planetary systems form ...

From its vantage point high above Earth’s atmosphere, NASA’s Hubble Space Telescope has completed this year’s grand tour of the outer solar system – returning crisp images that complement current and ...
