North America and the Pelican
Explanation: Fans of our fair planet might recognize the outlines of these
cosmic clouds. On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name
North America Nebula to the emission region cataloged as NGC 7000. To the right, just off the North America Nebula's east coast, is IC 5070, whose avian
profile suggests the
Pelican Nebula. The two bright nebulae are about 1,500 light-years away, part of the same
large and complex star forming region, almost as nearby as the better-known Orion Nebula. At that distance, the 3 degree wide field of view would span 80 light-years.
This careful cosmic portrait uses narrowband images combined to highlight the bright
ionization fronts and the characteristic glow from atomic hydrogen, and oxygen gas. These nebulae can be seen with binoculars from a dark location.
Look northeast of bright star Deneb in Cygnus the Swan, soaring high in the northern summer
night sky.

North American & Pelican Nebulae!
Interesting that they take that much room in the sky! I'm sure the
photo was enhanced!
Very nice photography!

Very nice photography! 8-)
You can't tell how big an astronomical object is by comparing it with a landscape unless you know the distance from the camera to the ground-based objects.
Here we're looking at a structure that is about 3.5° x 2.5°, or the width of seven full Moons.

Thanks; That makes sense!

I have been enjoying your site for decades! Thank you for your work and the oeuvre you have amassed. One thing that bothers me a bit is that sometimes, as with today's post, I look at the photo and imagine multiple images of the designated name, in this case the Pelican. Is it possibe and practical to have a roll-over outline what you are talking about? That would cure my ignorance. I hope you will give it some thought. Thank you!

Unfortunately, I think it would be too much work for our hard-working editors to provide roll-over outlines of nebulas.
But take a look at this picture of the Pelican Nebula:
And I can't resist saying this about myself:

I seem to have a nice palindrome number of posts at this very moment. I can't help it, I like it!

Still a pretty poor excuse for a pelican if I do say so myself. It looks more like a pterodactyl with its wings not fully extended:

For more than you ever wanted to know about 12221, see
https://number.academy/12221.
It's not a prime number, but all its factors (and prime factors) are also palindromes! - 1 , 11 , 101 , 121 , 1111 , 12221

Thanks, Johnny! That was indeed more than I ever wanted to know about 12221!
Now, do you have any info on 12222?
Maybe
this? Even though one letter, or number, is missing?

From the number.academy:
Perotto is asteroid number 12222. It was discovered by Observatorio Astronómico de San Vittore from Bologna on 11/19/1982.

Perotto? My goodness! I had an old classmate whose name was Per-Otto! Who knew he was an asteroid, if only he lost the hyphen of his name??
Or maybe
I'm the asteroid, and I'm really Perotto? Or I was, before I made this last post!

It's a small world indeed. Or perhaps the very BIG world is just full of notable coincidences
