The long-standing idea of planets forming in perfectly flat, orderly discs has been challenged by new research. Instead of calm, pancake-shaped structures of dust and gas, astronomers have now ...

Of the more than 6,000 known exoplanets in the Milky Way, so-called Sub-Neptunes are the most common. They are smaller than Neptune and more massive than Earth and believed to have rocky interiors ...

Astronomers have discovered an extrasolar planet with the largest core of any known planet. The discovery is especially exciting to planet formation theorists, because it provides extremely strong ...

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars, it is not expected to provide suitable conditions for the formation and ...

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and ...

Southwest Research Institute scientists propose a new model for the formation of compact exoplanetary systems that contain multiple rocky planets in tight orbits around their star. In this model, ...

In a pioneering discovery for astronomy, scientists have captured the very first signs of planet formation around a young star, offering an unprecedented look at how planetary systems like our own ...

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 ...

Planet formation used to sound straightforward: dust clumps into rocks, rocks grow into worlds, and the rest is detail. A cluster of recent discoveries has shattered that tidy picture, revealing ...
