NASA’s Hubble Space Telescope has captured infant planets colliding around Fomalhaut, one of the brightest stars in the night ...

When you look up at the night sky, planets seem calm and fixed. But a new study shows that nearby planetary systems can be ...

Two cosmic collisions near the star Fomalhaut solve the mystery of a disappearing "planet" and show rare planetesimal crashes ...

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

Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it ...

What looked like a mysterious exoplanet was actually the sparkling debris from a violent collision between massive space rocks.

NASA's Hubble Space Telescope has gotten a rare peek at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery.

Astronomers directly imaged two separate collisions between rocky objects in the Fomalhaut star system. Scientists previously thought the aftermath of one collision was a dust-covered exoplanet, ...

Two rare cosmic collisions around the young star Fomalhaut were caught by space telescopes, offering new clues about how planets form.

Hubble discovered a point of light in a neighboring star system, presumably a debris cloud from a celestial body collision.

The formation of Mercury remains an unsolved mystery. The planet closest to the Sun has a disproportionately large metallic core – accounting for about 70% of its mass – and a relatively small rocky ...

Scientists have shown that Earth’s basic chemistry solidified within just three million years of the Solar System’s formation. Initially, the planet was barren and inhospitable, missing water and ...
