NGC 7635: Bubble in a Cosmic Sea
Explanation: Do you see the bubble in the center? Seemingly adrift in a cosmic sea of
stars and glowing gas, the delicate, floating apparition in this widefield view is cataloged as NGC 7635 - The Bubble Nebula. A mere 10
light-years wide, the tiny
Bubble Nebula and the larger complex of interstellar
gas and dust clouds are found about 11,000
light-years distant, straddling the boundary between the parental constellations
Cepheus and
Cassiopeia. Also included in the
breathtaking vista is open
star cluster M52 (upper left), some 5,000 light-years away. The featured image spans about two
degrees on the sky corresponding to a width of about 375 light-years at the estimated distance of the
Bubble Nebula.

This is such a beautiful wide-field image. I understand that the stellar nursery NGC 7538 in the upper right has the largest protostar yet discovered.

I used this image as a background! The Bubble always intrigued me; it look just like a soap bubble! Dosen't seem possible way out in space that such an occurance could happen.

You are right about NGC 7538 and its
humongous protostar!!
This could be another
Trapezium in the making!

Thanks for the
retrospective. I missed it back in April. The
structure from the stellar wind evokes much more pleasure than a
Bud light and parallels editing music to an astrophographers use of image enhancement.

The nebula to the upper right of the image, from the selected color palette, could be called the Garfield Nebula

Fail to spot Garfield, I'm sorry...
What is the designation of that blue (in reality, OIII-rich) nebula at bottom right?

<<NGC 7538, near the more famous Bubble Nebula, is located in the constellation Cepheus. It is located about 9,100 light-years from Earth. It is home to the biggest yet discovered protostar which is about 300 times the size of the Solar System. It is located in the Perseus Spiral Arm of the Milky Way and is probably part of the Cassiopeia OB2 complex. It is a region of active star formation including several luminous near-IR and far-IR sources.>>

<<The constellations of Cassiopeia the Queen and Cepheus the King are filled with beautiful regions of Hydrogen gas (HII regions) and clusters of stars. In this image, the bright HII nebula at the top (slightly right of center) is Sh2-157 and is known as the Lobster Claw Nebula. In the lower left corner of the Lobster Claw Nebula is the open star cluster, NGC 7510. To the right and below Sh2-157 is NGC 7635, the Bubble Nebula. Although rather small in this wide field photo, close inspection of the high resolution version will reveal the bubble like feature that inspires its name. Down and to the right of the Bubble Nebula is the bright star cluster, M52. This beautiful cluster contains about 200 stars. The small bright nebula to the left of M52 is NGC 7538 (at 4 o'clock, close to the center of the image). The fairly bright nebula in the lower left of the image is Sh2-155, the Cave Nebula. The fainter nebula at 9 o'clock in the image is Sh2-154, while the cluster immediately above it is NGC 7419..>>

Yeah, well. Biggest cat, biggest protostar, same difference. (I think.)
The Lobster Claw Nebula, eh? It makes sense, I guess. There must be a hot luminous star in there to make it glow so bright in oxygen. (There must be a hot luminous star in the nebula, I mean. Who knows what is inside the cat!)

It looks to me like Garfield is a K class cat full of
titanium oxide with
various other metals. A little known fact is that
Aldebaran's (another K class cat) companion is named
Fred.

Not a K class cat, but an M class one, I bet. The M class ones are the ones that are full of titanium oxide that escapes from their poles, particularly from one of their poles.

<<Bubble Buddy is a sentient soap bubble created by SpongeBob when he felt alone in the episode "Bubble Buddy." At the Krusty Krab, he forces Squidward to remake his Krabby Patty several times in order to suit his alleged and outrageous preferences. Bubble Buddy is lactose intolerant, no cheese, drinks shampoo instead of soda, prefers no crust, ketchup under the patty, pickles to the left, four squirts of ketchup, wheat buns, non-deli lettuce, and farm raised tomatoes; carnival style - and at some point before eating requires a massage. He also pays for the meal in "Bubble money", which is not real and quickly pops out of existence. Later on, at Goo Lagoon, SpongeBob leaves Bubble Buddy with Scooter, who is buried up to his head in the sand, saying he will unbury him, and Scooter drowns when the high tide comes. When Bubble Buddy "has to go to the bathroom", SpongeBob leaves him in the bathroom for two hours, making everyone else wait. While dancing with Bubble Buddy, SpongeBob inadvertently insults the other dancing beach-goers by saying "shake that bubble butt", which the people take as calling them fat. When Bubble Buddy shakes Pearl's hand, which had just been dirtied by Grubby Grouper, making her never wanting to wash it again, it is cleaned off. After all these shenanigans, an angry mob is formed, who surround SpongeBob and Bubble Buddy. Just as he is about to be popped by a needle, Bubble Buddy suddenly comes alive and decides to leave, saying that "things are getting a little weird around here." A bubble taxi picks him up and he leaves with a suitcase and disappears into the sky. He then says, "Happy Leif Erickson Day!", to SpongeBob.>>

The best I can do is see Jon's shirt (he often wears a blue shirt).
Really, though, I'm forcing it. In the APOD image I grabbed it from, the "collar" actually looks more like a bathrobe, or perhaps Dr. Strange's cloak-collar. (The recent movie was excellent, I thought.) And Art is the best real-life person I'd put up against Dr. Strange in a game of Jeopardy.
