It's early summer and the irises are in bloom. They can survive about anywhere...even in space. Here is the Iris Nebula NGC7023.

(hey, that's the best lead I could come up with)

This nebula is in the northern sky during summer. It doesn't glow from its own energy and consists of mostly ash and dust. But it does happen to reflect the light from a really bright star nearby, SAO 19158.

The Iris is 1300 light years a way from us, in our own Milky Way galaxy. This is fairly close, which helps us to see it in detail since the lighted portion is smaller than many nebulas, at only 6 light years across.

The stuff closest to the star winds around and looks like smoke from an errant bottle rocket. While imagining a bottle rocket is a bit fanciful, what we see is indeed basically smoke. Who knows why it has this shape? The material is mostly inert and is likely junk from previous old supernovas. The thicker patches are almost black from blocking out the light behind.

This closeup shows the "bloom" portion. The whole nebula is quite a bit larger and is mostly tan and brown colored, as seen here around the edges of the picture.

To me it looks like a beaconing bright light. "Cross over, children, all are welcome!"

Resist. Must. Not. Walk. Toward. It.

The perfect celestial subject for listening to the Tord Gustavsen Jazz Trio performing The Other Side.

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.
