WR 102: A Rare Wolf-Rayet Star in the G2.4+1.4 Nebula

Revision title: Contrast Enhancement

This image showcases the Wolf-Rayet star WR 102, one of the hottest known stars in the Milky Way, with temperatures exceeding 200,000 K. Located in the Sagittarius constellation, WR 102 is a rare Wolf-Rayet star classified as a WO2, a type characterized by high levels of oxygen in its spectrum. Such stars are in an advanced stage of stellar evolution, shedding their outer layers through powerful stellar winds, which contributes to the star’s spectacularly high luminosity and unique spectral properties.

Accompanying WR 102 in this capture is the region G2.4 + 1.4. Imaging and processing this target was particularly challenging due to the dense star field surrounding it, which tends to obscure the target. The complexity of this field required careful work to isolate and emphasize WR 102 while preserving the intricate details of the surrounding stars and nebulae.

Hope you like it!

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.
