Bernes 149 in Scorpius

Bernes 149 in Scorpius

Bernes 149 is an obscure nebula complex consisting of the reflection nebula GN 16.05.2 at the centre of an elongated dusty dark nebula. Although mostly unknown to amateurs, it has been well studied by professionals and is also known as the Lupus 3 cloud. The name comes from its connection with many other dark clouds in the constellation of Lupus. Near the centre of the image are the blazing bright stars HR 5999 and HR 6000. They belong to a class of YSO known as Herbig Ae/Be stars, which are intermediate mass pre-main sequence precursors to supergiant stars. The central reflection nebula is illuminated by HR 5999, the southern of the pair. Out of all the Lupus clouds, Lupus 3 exhibits the highest rate of star formation. Searches for young stellar objects have yielded the detection of more than a hundred x-ray sources in a 30 arcminute radius around HR 5999 and HR 6000. The Lupus 3 cloud also contains protostars with detected jets and outflows and Herbig Haro objects have been found near the central region (not visible in image). Near the bottom right corner is the small reflection nebula GN 16.01.6. The Lupus clouds are approximately 450-650 light years away (text and target suggestion by Sakib Rasool).
