Disc around the star HD 97048
Using the ESO’s SPHERE instrument at the Very Large Telescope, a team of astronomer observed the planetary disc surrounding the star HD 97048 in the constellation of Chameleon, about 500 light-years from Earth. The juvenile disc is formed into concentric rings. This symmetry is in contrast to most protoplanetary systems which contain asymmetrical spiral arms, voids and vortexes.
The displayed image is a composite derived from two independent observations that targeted the inner and outer regions of this disc.
The central part of the image appears dark because SPHERE blocks out the light from the brilliant central star to reveal the much fainter structures surrounding it.
