Cosmic Bubble: A massive bubble is being blown outwards into space by a central super-hot, massive star in this picture of the aptly named “Bubble Nebula”, or NGC 7635. The diameter of the bubble is 7 lightyears, which is about 1.5 times the distance from our sun to the nearest star: Alpha Centauri. The object is located at 7,000-10,000 lightyears from earth

The Bubble itself is the result of a massive star (45x the mass of our sun) expelling a superhot stellar wind, which moves over 4 million miles per hour, sweeping up cold, interstellar gas as it expands outwards.

The image was taken in November of last year from my rooftop in Tokyo, Japan with a apo refractor and cooled DSO camera.

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.
