Astronomers have long believed that the swirling disks of gas and dust that form planets around young stars last only about ...

Researchers discovered a planet-forming disk that lasted 30 million years. This challenges previous estimates of 10 million years.

“Earthrise” begins with a quotation from William Anders, who, as a member of the first crew to circle the moon, took the ...

"The signs tend to show a planet embedded within Elias 2-24 that is causing a disturbance in the flow and warming its surroundings, indicating that it is still undergoing formation," said Iain.

Planet formation around low-mass stars may be suffering from Peter Pan syndrome. While previous observations and models have suggested that a disk of planetary building blocks should be 'fully ...

We also have an extremely strong planet formation theory group, working on problems of planet-disc interaction, gravitational stability of discs, N-nody planet formation models and the influence of ...

An curved arrow pointing right. Much about planet formation is not understood. Astronomers suspect that planets form from a disk of gas and dust that clumps together over time, to form giant planets.

This suggests planetary formation follows the evolution of a galaxy with a ring of planet formation moving outward over time. The search for exoplanets has largely been one of surveying nearby stars.

"We described them as 'never growing up' because they have maintained their primordial disk long after the expected time frame for primordial disks to have dissipated." Planet formation around low ...
