Artist’s concept of NO Lupi, a hot young class III star located 400 light-years away from Earth in the Lupus Star Forming Region. NO Lupi was observed to have a disk of dust and gas, making it a likely candidate for comet and asteroid formation. The star is also providing a unique look into planetary system formation as the gas surrounding it is flowing rapidly away from the star at a rate of 22 kilometers per second (2,237 mph).

A team of astronomers, led by scientists from the University of Cambridge in the U.K., said on November 30, 2020, that they’ve discovered carbon monoxide gas flowing at an unprecedented rate from a young star system some 400 light-years from Earth. They said the discovery represents a unique stage in the evolution of planets, not previously seen in young, low-mass stars.
The finding might help astronomers understand how solar systems form.
The scientists originally surveyed 30 young stars at similar stages of evolution in dense, dark star-forming clouds – located in the direction of the southern constellation Lupus the Wolf – and hence called the Lupus Star Forming Region. The scientists were ...
