Rosette Nebula: The Heart of a Rose
Chandra X-ray Observatory | 08 Sept 2010

Click to view full size image

This composite image shows the Rosette star formation region, located about 5,000 light years from Earth. Data from the Chandra X-ray Observatory are colored red and outlined by a white line (roll your mouse over the image above). The X-rays reveal hundreds of young stars in the central cluster and fainter clusters on either side. Optical data from the Digitized Sky Survey and the Kitt Peak National Observatory (purple, orange, green and blue) show large areas of gas and dust, including giant pillars that remain behind after intense radiation from massive stars has eroded the more diffuse gas.

A recent Chandra study of the cluster on the right side of the image, named NGC 2237, provides the first probe of the low-mass stars in this satellite cluster. Previously only 36 young stars had been discovered in NGC 2237, but the Chandra work has increased this sample to about 160 stars. The presence of several X-ray emitting stars around the pillars and the detection of an outflow -- commonly associated with very young stars -- originating from a dark area of the optical image indicates that star formation is continuing in NGC 2237. By combining these results with earlier studies, the scientists conclude that the central cluster formed first, followed by expansion of the nebula, which triggered the formation of the two neighboring clusters, including NGC 2237.

Baby stars in the Rosette cloud
ESA Portal - 12 April 2010

Click to view full size image

Herschel’s latest image reveals the formation of previously unseen large stars, each one up to ten times the mass of our Sun. These are the stars that will influence where and how the next generation of stars are formed. The image is a new release of ‘OSHI’, ESA’s Online Showcase of Herschel Images.

Infrared image of the Rosette molecular cloud. Herschel collects the infrared light given out by dust and this image is a three-colour composite made of wavelengths at 70 microns (blue), 160 microns (green) and 250 microns (red). It was made with observations from Herschel’s Photoconductor Array Camera and Spectrometer (PACS) and the Spectral and Photometric Imaging Receiver (SPIRE). The bright smudges are dusty cocoons containing massive protostars. The small spots near the centre of the image are lower mass protostars.

WISE Captures the Unicorn's Rose | 25 Aug 2010

NGC 2237: Rosette Nebula

Unicorns and roses are usually the stuff of fairy tales, but a new cosmic image taken by NASA’s Wide-field Infrared Explorer (WISE) shows the Rosette nebula located within the constellation Monoceros, or the Unicorn.

This flower-shaped nebula, also known by the less romantic name NGC 2237, is a huge star-forming cloud of dust and gas in the Milky Way Galaxy. Estimates of the nebula’s distance vary from 4,500 to 5,000 light-years away.

At the center of the flower is a cluster of young stars called NGC 2244. The most massive stars produce huge amounts of ultraviolet radiation, and blow strong winds that erode away the nearby gas and dust, creating a large, central hole. The radiation also strips electrons from the surrounding hydrogen gas, ionizing it and creating what astronomers call an HII region.

Although the Rosette nebula is too faint to see with the naked eye, NGC 2244 is beloved by amateur astronomers because it is visible through a small telescope or good pair of binoculars. The English astronomer John Flamsteed discovered the star cluster NGC 2244 with a telescope around 1690, but the nebula itself was not identified until John Herschel (son of William Herschel, discoverer of infrared light) observed it almost 150 years later.

The streak seen at lower left is the trail of a satellite, captured as WISE snapped the multiple frames that make up this view.

This image is a four-color composite created by all four of WISE’s infrared detectors. Color is representational: blue and cyan represent infrared light at wavelengths of 3.4 and 4.6 microns, which is dominated by light from stars. Green and red represent light at 12 and 22 microns, which is mostly light from warm dust.

Hello, there a image from ROSA ( Remote Observatory Southern Alps ) South France remotly from Germany
http://www.rosa-remote.com/213.0.html



regards,
Knut Schäffner

Stunningly beautiful! Thank you to all who take the time to post their images.

There is surely a Rose for every taste here! Thank you very much for this cosmic rosarium!

Ann

And now that everyone has rose to the occasion and petalled their wares, shall we leaf well enough alone -- stem the tide, so to speak -- and return to our roots? Perhaps a picture of a Thorne-Zytkow Object?

I googled Thorne-Zytkov Object and got, among other things, this "image" (yep, it was posted as an image):



Oh, I found this image, too (and it is more like an image):
I guess the message here is that you need to belong to a civilization that is infinitely advanced if you want to see, still less control or own, a Thorne-Zytkov Object! But at least you've got an image of one (or two) now, Rob, so enjoy!
