The star in the centre of the green area is very old. It has puffed off its outer layers and set them glowing green and red.
Old stars puff off their outer layers when they are running short of the fuel that they burn to shine. As the fires run low, the outer "ashes" fall inwards and then bounce outwards again. Eventually, the central brightness will fade and the outer layers will mix with other gases in space to form new baby stars.

Face Mounted Acrylic is a frameless presentation of photos printed on best quality metallic photo paper, face mounted or bonded to the rear of a 6mm thick high quality transparent acrylic panel using archival transparent film, and 2mm black acrylic glued to the back of the photo for protection. It is considered the Rolls Royce of photo presentation and is sometimes referred to as “float frames” as they sit off the wall and appear to be suspended in mid air about an inch from the wall.
