Sharpless 239 (Sh2-239 or LBN 821) is a cloud of ionized gas, embedded in the dark nebula LDN 1551. This region lies near the southern end of the Taurus molecular cloud complex, the distance of this object is about 450 light years.
In this region active star formation is taking place. Lots of embedded young stellar objects are driving dynamic outflows into the surrounding interstellar medium, including a compact, red jet near the infrared source IRS5, which is known to be a system of protostars surrounded by dust disks. IRS5 is associated with a bipolar HH object known as HH 154 and a large number of shock waves, some of them are also classified as HH objects, in particular HH 28, 29, 258, 259, 262 and 286.
Other nearby young stellar objects, among them the T Tauri stars HL Tau and XZ Tau supply energy to other jets, such as HH 30.
Herbig–Haro objects (HH) – after the astronomers George Herbig and Guillermo Haro – are narrow jets of gas and matter ejected by young stars at speeds of 100 to 1000 kilometers per second that collide with the surrounding nebula, producing bright shock fronts that glow as the gas is heated by friction while the surrounding gas is excited by the high-energy radiation of nearby hot stars. They are ubiquitous in star-forming regions, and several are often seen around a single star. The stellar jets seem to form as the swirling cloud of dust and gas surrou

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.
