CAPE CANAVERAL, Fla. — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

An image from the ALMA telescope array in Chile shows jets of silicon monoxide blowing away from the young star HOPS-315. The blue jet is moving towards Earth, and the red jet is moving away from us.

A new study published in The Astrophysical Journal has traced six chemically distinct families of the Solar System's oldest meteorites to a single ring-shaped dust trap just beyond Jupiter's orbit — ...

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space's oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.

Researchers in the U.S. have found evidence that a large planet may have existed billions of years ago - before meeting a ...

A team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...
