The picture shows the magnificent globular cluster NGC 2108. It lives on the territory of the Large Magellanic Cloud in the constellation Golden Fish. In 1835, he was first found by mathematician, chemist and inventor John Herschel (the son of William Herschel).
The most striking feature of this species is the brilliant ruby-red spot in the center on the left. Here is a carbon star. Such objects almost always represent cold red giants with an atmosphere in which there is more carbon than oxygen. Carbon monoxide is formed in the outer star layer by a combination of these elements until more oxygen appears. Carbon atoms are then able to create many different carbon compounds, like C2, CH, CN, C3, and SiC2, scattering blue light inside the star.
The picture was taken on an improved Hubble Space Telescope camera using three different filters.
