When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...
Protoplanetary disks are the birthplaces of planets, but few discoveries have stretched scientific expectations like IRAS ...
A study led by Jenny Frediani at Stockholm University has revealed a planet-forming disk with a strikingly unusual chemical composition: an unexpectedly high abundance of carbon dioxide (CO 2) in ...
New ALMA observations of protoplanetary disks allow us to probe planet formation in other systems, giving us new constraints on planet formation processes. Meanwhile, studies of our own Solar System ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing ...
Computer simulation of the disruption of a star by a black hole shows the formation of an eccentric accretion disk of stellar material spiraling into the black hole. This image from a video of the ...
