When exoplanet scientists first spotted patterns in disks of dust and gas around young stars, they thought newly formed planets might be the cause. But a recent NASA study cautions that there may be another explanation—one ...

Using the Atacama Large Millimeter Array (ALMA) in Chile, an international team of researchers has studied the disc surrounding the star MWC 758. The new observations reveal further insights into the complex morphology of ...
A team of U.S. astronomers studying the star RZ Piscium has found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed ...

(Phys.org)—A team of researchers affiliated with several institutions in Japan has found evidence showing that condensed aluminum oxide dust surrounding the star W Hydrae plays a key role in accelerating the stellar wind. ...
Black holes get a bad rap in popular culture for swallowing everything in their environments. In reality, stars, gas and dust can orbit black holes for long periods of time, until a major disruption pushes the material in.

(Phys.org)—In a research paper published Apr. 3 on arXiv.org, astronomers presented a close-up view of the circumbinary disk HD 142527 obtained with the Atacama Large Millimeter and submillimeter Array (ALMA) in Chile. ...
Consider that the Earth is just a giant cosmic dust bunny—a big bundle of debris amassed from exploded stars. We Earthlings are essentially just little clumps of stardust, too, albeit with very complex chemistry.
