M27 Dumbbell Nebula

The Dumbbell Nebula (M27) is located about 1200 light years from earth in the constellation Vulpecula (The Fox) and is the first "planetary nebula" discovered in 1764 by Charles Messier (the "M" in M27). When seen by a good set of binoculars or a small telescope throughout the summer and fall, it will have a more characteristic "dumbbell" shape.

A planetary nebula is what happens when a intermediate star reaches its end of life and fusion stops. A red giant is formed and the core eventually falls in on itself forming a white dwarf star. The outer atmosphere/gas that has been ejected is ionized giving off the colors you see in this image.

Two interesting facts about planetary nebula: 1) This is actually how our Sun is supposed to end its life cycle in roughly five billion years (our Sun is middle aged for those that wonder); 2) while the star at the center of this and other planetary nebulas live for billions of years...the planetary nebula is only around for about 10,000 years before fading so we are lucky to see this giant Dumbbell at all!

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.
