APOD: Long Stem Rosette Nebula (2021 Feb 14)

Post by APOD Robot » Sun Feb 14, 2021 5:08 am

Image Long Stem Rosette Nebula

Explanation: Would the Rosette Nebula by any other name look as sweet? The bland New General Catalog designation of NGC 2237 doesn't appear to diminish the appearance of this flowery emission nebula, at the top of the image, atop a long stem of glowing hydrogen gas. Inside the nebula lies an open cluster of bright young stars designated NGC 2244. These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas. Ultraviolet light from the hot cluster stars causes the surrounding nebula to glow. The Rosette Nebula spans about 100 light-years across, lies about 5000 light-years away, and can be seen with a small telescope towards the constellation of the Unicorn (Monoceros).

There are no fewer than six O-type stars in cluster NGC 2244, the cluster that is ionizing the long-stemmed Rose.

What about the yellow star among them? Is that the Betelgeuse of the Rosette?

No, that's a foreground intruder, a bold yellow boy trying to woo the hot blue gals in the Rosette!

The enlargement of the nebula is absolutely gorgeous! Thanks APOD, Adam Block, and Tim Puckett

Hmmm... an ionizing long stem rose sounds like the sort of gift Putin would hand one of his enemies!

Indeed, it would not look as romantic if they had named it the Demogorgon Nebula.

The Rosette Nebula actually has two stems, one of which connects it to the Cone Nebula/Christmas Tree Cluster nebular complex!

A Siamese twin cosmic Rose?

<<"Our state has a long connection with the space industry," said Rep. Nicole Miller, who co-authored House Bill 1292. "Every year, hundreds of people from around the country gather in Oklahoma’s panhandle to stargaze at Black Mesa State Park, and by naming a state astronomical object, we’re helping to promote tourism in our state and encourage STEM (science, technology, engineering and math) education."

"The Oklahoma Panhandle, which is home to Black Mesa State Park, is known for some of the darkest night skies in the United States, which makes for fantastic stargazing opportunities," Patzkowsky said. "Combined with Black Mesa being the highest point in the state, we already attract one of the largest stargazing parties in the country."

Hey, Johnny, you've now got 405 posts, so I dub you "The Knight of the IC 405 Nebula"! :D

How long is the stem of the long-stemmed Rosette? From the images, most clearly the one Ann posted, it looks like the stem is about twice as long as the Rosette nebula is in diameter. So, perhaps 250 light years. That's a very long stem.

How hot are the blue gals in NGC 2244 ? I'm discovering that this is a harder question for which to find ready answers. The brightest two are at spectral class O4V and O5V. I think we're talking about temperatures of 40,000 K or more. They're very hot!

I see one of the links notes that the idea of giving flowers was popularized by the King of Sweden.

Happy Valentine's Day to you all !

Thanks, and nice coincidence! 'Tis but a rose by another name, and it indeed looks as sweet. From https://en.wikipedia.org/wiki/IC_405:
IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula[1] in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA 05h 16.2m dec +34° 28′.[2] It surrounds the irregular variable star AE Aurigae and is located near the emission nebula IC 410, the open clusters M38 and M36, and the K-class star Iota Aurigae. The nebula measures approximately 37.0' x 19.0', and lies about 1,500 light-years away from Earth.[2] It is believed that the proper motion of the central star can be traced back to the Orion's Belt area.[2] The nebula is about 5 light-years across.[1]
