Bernes 149, Lupus 3 dark cloud 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). The Lupus clouds are approximately 450-650 light years away (text and target suggestion by Sakib Rasool)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
