According to standard planet formation theories, planets are created from the disks of gas and dust surrounding newborn stars.

Astronomers have discovered a giant Saturn-sized planet orbiting TOI-6894, the smallest star ever known to host such a world.

An international team of astronomers, co-led by researchers at the University of Galway, has made the unexpected discovery of ...

The remaining dust and gas form a protoplanetary disk that encircles the new star, which slowly accretes to form systems of planets.

That’s where his argument engages the idea of planet formation. Planets like Jupiter are formed from the bottom-up by first building-up a rocky core that is subsequently enshrouded in a massive ...

The textbook picture of how planets form—serene, flat disks of cosmic dust—has just received a significant cosmic twist.

A quick guide to planets, including the eight in our solar system, how they form, and how many could be in the universe.

New observations of dust around young stars suggests collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn't likely stop the formation of rocky planets like ...
