The Bubble Nebula - a NHO Color Mapped Mosaic From The Hubble telescope

This colorful image of the Bubble Nebula – also known as NGC 7635 – was taken by the Hubble Telescope in 2016 with the Hubble’s WFC3 instrument package. The Bubble Nebula is believed to be about 8,000 light years distant and to have been formed by the intense stellar winds of the bright star to the left of center which has created a nearly symmetrical bubble in the surrounding molecular cloud which resists the bubble’s expansion. The intense ultraviolet radiation of the central star causes the surrounding gasses to emit light in specific wavelengths which was then captured by the Hubble Telescope and its specialized filters. This image is composed of three emission line filter images – N II, Hydrogen alpha and O III – which were then mapped to red, green and blue respectively and then combined as a false color image.

This is my processing of the Hubble Telescope data of the Bubble Nebula. The mosaic data was released in May 2016 and can be found at this link if you want to try processing it --> https://archive.stsci.edu/prepds/heritage/bubble/introduction.html

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.
