A recent study accepted for publication in The Astrophysical Journal Letters discusses how astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to examine protoplanet HD 169142 b, ...

The study suggests that the Moon likely formed largely from Earth’s mantle material — with minimal involvement from Theia.

The protoplanet Vesta, once a fuzzball in telescopic images, is revealing a surprising range of features – from a mountain with a rise three times higher than Mt. Everest's to a puzzling band of ...

New images suggest the protoplanet has carved a ring-shaped gap in the disk. This suggests other protoplanetary disks containing spirals may also harbour yet undiscovered planets, scientists said.

When the planet is still forming, i.e. when it is still gathering material, it is called a protoplanet. To date, only two protoplanets had been unambiguously identified as such, PDS 70 b and c ...

Vesta had been thought to have been the last protoplanet, a leftover remnant from the early days of our solar system that never quite made it as a fully fledged planet for some reason.
