Blown by fast winds from a hot, massive star, this cosmic bubble is much larger than the dolphin it appears to be.

Catalogued as Sharpless 2-308, but often referred to as the Dolphin Nebula, it lies some 5,200 light-years away toward the constellation of Canis Major and covers slightly more of the sky than a full Moon.

The massive star that created the bubble, a Wolf-Rayet star, is the bright one near the centre of the nebula.

Relatively faint emission captured in this image is dominated by the glow of ionized oxygen atoms mapped to a blue hue.

Captured via the use of a remote telescope located at the El Sauce Observatory in the Rio Hurtado Valley in Chile, South America, the final image comprises 6hrs of broadband data using a combination of Ha and Oiii filters.

The final image took several hours/days to achieve with post-processing carried out using PixInsight, Adobe Photoshop and Adobe Lightroom.

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.
