Circinus West is a cold, dense cloud of gas and dust that stretches out for 180 light-years, around 60 times the size of our solar system.

The Circinus West molecular cloud has been captured by the 570-megapixel Dark Energy Camera (DECam). DECam is mounted on the ...

Chandra - along with ESO's Very Large Telescope Array - spied a bright, variable supernova blast located in a galaxy 12 million light-years away. This image is a composite showing the central ...

Sebastian Heinz and his team at the University of Wisconsin-Madison (UW) discovered that Circinus X-1 is less than 4,600 years old, making it the youngest X-ray binary system ever seen.

If thissecond scenario is correct, Circinus X-1 would have one of the longest,narrowest jets found to date, surpassing even those discovered around blackholes. Top 10 Star Mysteries ...

Circinus X-1, as the system is called, is a high-mass X-ray binary, a pair of heavy stars in orbit around each other. We know of quite a few objects like this in the galaxy, but most of them are ...

There are so many stars and so much dust from our own galaxy obscuring the Circinus galaxy. In fact, this galaxy has two extended spiral arms, which look like a great green “S” in this WISE image.
