Wolf-Rayet (WR) stars are stars that show large and prominent emission lines of ionized helium and highly ionized nitrogen or carbon. Spectra indicate a high surface build-up of heavy elements, hydrogen depletion and strong stellar winds. The surface temperatures of known Wolf-Rayet stars range from 20,000 K to about 210,000 K, hotter than almost all other types of stars. WR 134 is actually one of the first WR stars discovered by astronomers Charles Wolf and Georges Rayet in 1867.

WR 134 has shed its atmosphere, which is now disrupted by the hot, fast winds of the WR star, forming a visible bubble. It is more easily observed in the light of ionized oxygen ([OIII]) and therefore appears turquoise in images of the WR bubble. WR 134 itself is visible as the brightest star near the apparent centre of the bubble.

Other objects in this image include two barely visible open star clusters: NGC 6883 (below WR 134) and NGC 6871, the large red-emitting nebulae LBN 182 (below WR 134) and LBN 187, and some dark nebulae, notably Barnard 147.

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.
