Millions of planets could come into being in the most turbulent regions of galaxies, near supermassive black holes. For a ...

Active galactic nuclei (AGNs) occur when supermassive black holes are surrounded by vast amounts of gas and dust that swirl ...

Terrestrial planets—Mercury, Venus, Earth and Mars—formed by the accretion of smaller objects. The Earth was probably the latest terrestrial planet to form and reached about 99% of its final mass ...

Astronomers have found evidence of a process that supports an alternative, more rapid approach to planetary formation, more top down than bottom up. By Katrina Miller When it comes to making a planet, ...

Instead of a tempest in a teapot, imagine the cosmos in a canister. Scientists have performed experiments using nested, spinning cylinders to confirm that an uneven wobble in a ring of electrically ...

A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. A fresh look at past data reveals that ...

The formation of planets is a fascinating process. They usually originate in a disc of dust and gas surrounding stars. When particles come together, they form a clump, and through a process called ...

With about 6,300 exoplanets discovered so far and more than 10,000 candidates awaiting confirmation, it’s easy to forget the ones that started it all: the very first exoplanets discovered and ...

One way gas giants form is through core accretion, where solid cores gradually grow in a disk by pulling in rocky and icy pebbles until they become massive enough to attract the gas that surrounds ...
