Figure 1: Jet, disk, and outflow in the HH 211 protostellar system. (Top) A composite image showing the jet system. (Bottom) A zoom-in to the innermost region around the central protostar, showing the ...

The Wolfe Disk, a massive rotating disk galaxy in the early universe, was discovered in 2017 when a stargazing project in the Chilean desert examined light from a distant quasar (top left) absorbed in ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a young star surrounded by an astonishing mass of gas. The star, called 49 Ceti, is 40 million years old and ...

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 ...

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 ...

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 ...
