Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them.

It was once thought that when an aging star engulfed a planet it would be a dramatic event. Now, the Webb telescope has ...

Observations from NASA's James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is ...

Over the past 20 years, astronomers have been studying a massive, 100 billion-mile-wide (161 billion kilometers) circumstellar disk of dust and gas surrounding Vega, similar to the protoplanetary ...

Lingering Brightness Provides Evidence for How the Planet Met Its Demise Each year, scientists from around the world compete ...

NASA recorded the death of a planet at the hands of a star in an unprecedented event using the unparalleled capacity of the ...

The James Webb Space Telescope has performed 'post-mortem' of a cosmic scene after a planet was swallowed by the star it was ...

Circumstellar disk—Dust and gas forming a disk in orbit around a star. Some circumstellar disks may contain planetary systems. Comet—A small solar system body made of ice and dust that moves ...

"These observations separate light from the protoplanet and light from the circumstellar disk in which it is embedded with this unique capability." The findings were published in February in the ...

At first the circumstellar disk is in a phase called an accretion disk, where mass is transported inward toward the star and angular momentum is transported outward. Planet formation likely occurs ...

This seemed odd and illogical as when the Solar system formed, it would be expected that objects that developed in the circumstellar disk would orbit around the Sun on a more or less flat plane ...

Simulations show that these objects could form during violent collisions between circumstellar disks around young stars. These collisions, occurring at impressive speeds, create bridges of matter that ...
