An infrared image of the binary CS Cha with the newly discovered companion in the dotted circle. After a mouse click you can see the image viewed with special polarization filters that make dust discs and exoplanets visible. The companion seems to have his own dust disc. (c) C. Ginski & SPHERE
Infographic of the binary star CS Cha and its surrounding dust disc (left) with the newly discovered companion (right). The companion is located at more than 214 times the distance earth-sun fromthe binary, but clearly belongs to the system. The whole system is about 165 parsec (538 light years) away from Earth.

In the future, the researchers want to examine the star and the companion in more detail. They want to use the international ALMA telescope on the Chajnantor plateau in the North Chilean Andes.
