A perfect sight for a Summer night.

Gossamer gasses floating effortlessly through our galaxy in a closeup of the Eastern Veil Nebula (NGC6995).

This more detailed shot shows how expanding gasses are still actively circulating after 15,000 years.

It was then that a star 20 times bigger than our sun blew up, scattering refuse in all directions like a popped balloon. The blast would have been bright enough to see even in daytime here on Earth.

The cloud is so named "Veil" because a great deal of the gas is in super-thin layers and sheets. The brighter areas are where we see them on-edge, or they're folded up. The effect is similar to shear pleated shades, waving in the breeze through our windows.

Red=Hydrogen ionized by nearby stars.
Cyan=Oxygen reflecting the color of nearby stars.

The nebula is not particularly bright (a nearly 3-hour exposure makes it easier to see), so it's a credit to early telescopes that the feature was discovered in 1784 by William Herschel...or, more likely, Caroline Herschel. Ol' Bill often got the credit for the work of his younger sister...such was the day. They made many discoveries and, in fact, were a pretty good team.

The entire Veil nebula is in an adjoining spiral arm of our galaxy, 2400 light years away. After so many centuries, the nebula has grown to 110 light years across.
Eventually, the gasses will spread out so much that we'll no longer be able to see the feature.

I was lucky to score a night of clear weather, with little haze from the northern wildfires!

Such is the universe tonight as I listen to Beegie Adair and his piano performing the jazz piece, 𝘉𝘦𝘸𝘪𝘵𝘤𝘩𝘦𝘥.

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.
