Wolf-Rayet 23 and its Associated Bubble in LRGB

Wolf Rayet 23 (WR 23), the bright blue star in the centre of this field (also catalogued as HD92809), is a massive star (30-40 times the mass of our Sun) located in the southern constellation Carina, about 5,900 light-years from Earth. It is surrounded by a bubble-shaped structure that is created by intense stellar winds blowing off WR 23's outer layers of gas. The bubble is estimated to be around 10 light-years in diameter, expanding at a rate of about 60 kilometers per second.
WR 23 is much hotter than our Sun (about 100,000 kelvin compared to the surface of our Sun at around 5,500 kelvin) and consequently about 2 million times as luminous.

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.
