The target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our sun—at a distance of about 4,600 light-years. The cluster contains hundreds of massive stars as ...

The star cluster Cygnus OB2 contains more than 60 O-type stars and about a thousand B-type stars. At a relatively nearby distance to Earth of about 5,000 light years, Cygnus OB2 is the closest ...

The team found these treacherous regions by performing long-term observations of an object known as Cygnus OB2. At 4,600 light-years away, this is the closest large star cluster to Earth ...

The star cluster Cygnus OB2 contains more than 60 O-type stars and about a thousand B-type stars. Astronomers have used deep observations with NASA’s Chandra X-ray Observatory to detect the X ...

It is a region of intense formation of massive (and consequently short-lived) stars, with two young star clusters Cygnus OB2 and NGC 6910. "The HAWC detector has greater sensitivity and angular ...

This month, we’ll be pointing our telescopes toward the Perseus spiral arm of our galaxy near the galactic anticenter. Specifically, we’ll stay within the 12°-by-12° boundary of the Perseus ...
