In this larger image is the open cluster NGC 6193 that was part of the Caldwell Catalog. Surrounding it are two nebulae: the Fighting Dragons of Ara (NGC 6188) who are "fighting" over the Dragon's Egg Nebula (NGC 6164/6165). The open cluster was discovered by James Dunlop (1793-1848) in 1826, but it is unlikely that he saw the surrounding nebulosity very well. The entire scene is best seen during the winter months in the southern hemisphere.

This is the Rim Nebula! 💖💖💖

This star forming nebula has been drastically shaped by a nearby open star cluster known as NGC 6193. The rampant star formation was caused to a bunch of supernovae taking place during the last batch of stars - meaning that some of these stars are very young (only a few million years old)! 🌃🌃🌃

Blazing O-Type Stars

the open star cluster Caldwell 82 (NGC 6193) is home to a couple O-Type stars, the most massive and luminous ones known. they can get hotter than 30,000 Kelvin (our Sun is about 5,800 K), can be a million times more luminous than the Sun, and die young in violent supernova explosions, creating black holes or neutron stars

Lose yourself in 50 breathtaking new images released for the Hubble anniversary

Lose yourself in 50 breathtaking new images released for the Hubble anniversary

In April of 1990, our Universe opened up to us in a whole new way.

That’s when the Hubble Space Telescope was launched and deployed, the most powerful space telescope ever created.

Although the instrument got off to a bumpy start, Hubble has, as of April this year, been in operation for a full three decades. And, in celebration of this marvellous milestone, NASA has just handed us space riches: 50 newly processed images of objects from the Caldwell catalogue, released to the public for the first time.

Cosmic objects can be categorised in many different ways. What makes the Caldwell catalogue special is that it contains only objects that can be observed by backyard astronomers. Grab a telescope (or, in some cases, your own two eyes), and you can find these objects for yourself in the night sky.

The Caldwell catalogue, compiled by amateur astronomer and writer Sir Patrick Alfred Caldwell-Moore, was first published in 1995 in Sky & Telescope, intended as a complement to the Messier catalogue of 110 objects compiled by French astronomer Charles Messier in the 18th century.

Messier, famously, compiled his catalogue out of frustration. He was interested in finding comets; the catalogue was a list of annoying things that weren’t comets, and that could therefore be safely ignored by comet hunters.

Ironically, it turned out to be a really useful list of bright targets for amateur astronomers to look at, including nebulae, star clusters, and nearby galaxies.

The Caldwell catalogue, containing 109 objects, consists of 28 nebulae, 46 clusters, and 35 galaxies that were not included in the Messier catalog, but are still of intense interest for anyone who enjoys looking skyward at night.

There’s a joy to be had in finding these objects yourself, and in seeing them, light-years away, with your own eyes. There’s also joy in comparing your own observations to what Hubble has seen with its much more powerful “eye”. And, well, they’re just glorious.

Thirty Caldwell objects feature in the 50 new NASA images, with some objects appearing in more than one image.

“Because of Hubble’s detailed field of view, some of its pictures do not capture the entirety of a Caldwell object, sometimes instead zooming in on clusters of young stars in the arms of a spiral galaxy, stars on the outskirts of a cluster, or the zombie star at the heart of a nebula,” wrote Vanessa Thomas of NASA’s Goddard Space Flight Center on the NASA website.

“But in other cases, a mosaic of Hubble observations assemble to create a complete or nearly complete portrait of the celestial marvel.”

In total, Hubble’s Caldwell catalogue – first published in December of 2019 – now includes 87 of the 109 Caldwell objects. The space telescope hasn’t ignored the Messier catalogue, either; Hubble has imaged 96 of the 110 Messier objects. Each object in both catalogues includes a viewing guide for how to see it in the sky.

Together, the two collections contain some of the most breathtakingly beautiful images of the space around us – an awe-inspiring tour of the wonders of the cosmos.

And an absolute testament to the priceless treasure Hubble has turned out to be.

RCW 108 is a region where stars are actively forming within the Milky Way galaxy about 4,000 light years from Earth. This is a complicated region that contains young star clusters, including one that is deeply embedded in a cloud of molecular hydrogen.  By using data from different telescopes, astronomers determined that star birth in this region is being triggered by the effect of nearby, massive young stars.

This image is a composite of X-ray data from Chandra (blue) and infrared emission detected by Spitzer (red and orange). More than 400 X-ray sources were identified in Chandra's observations of RCW 108.   About 90% of these X-ray sources are thought to be part of the cluster and not stars that lie in the field-of-view either behind or in front of it.  Many of the stars in RCW 108 are experiencing the violent flaring seen in other young star-forming regions such as the Orion Nebula. Gas and dust blocks much of the X-rays from the juvenile stars located in the center of the image, explaining the relative dearth of Chandra sources in this part of the image.

The Spitzer data show the location of the embedded star cluster, which appears as the bright knot of red and orange just to the left of the center of the image.  Some stars from a larger cluster, known as NGC 6193, are also visible on the left side of the image.  Astronomers think that the dense clouds within RCW 108 are in the process of being destroyed by intense radiation emanating from hot and massive stars in NGC 6193.

Taken together, the Chandra and Spitzer data indicate that there are more massive star candidates than expected in several areas of this image.  This suggests that pockets within RCW 108 underwent localized episodes of star formation. Scientists predict that this type of star formation is triggered by the effects of radiation from bright, massive stars such as those in NGC 6193. This radiation may cause the interior of gas clouds in RCW 108 to be compressed, leading to gravitational collapse and the formation of new stars.

NGC6188 aka The fighting dragons of ara, is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188. NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova. Image also show NGC 6164 which is a bipolar emission nebula of about 4 light-years across that lies some 4,200 light-years away in the southern constellation of Norma. It is approaching us at approximately 53.9 kilometers per second. Its symmetric gaseous shroud and faint halo surround the blue, young, central star HD 148937, the brightest member of a triple star system orbiting around each other, which fierce stellar winds – of about 8 million kilometers per hour – created this nebula.

About 4, 000 light years away in our own Milky Way galaxy, RCW 108 is a dynamic region of star birth and formation. More information:

NGC 6193, C82 // John Bozeman

Seen here against the Fighting Dragons of Ara (NGC 6188) is the open cluster NGC 6193 about 3,700 light years away in the constellation of Ara, the Altar. This cluster is home to about 30 stars, two of which are bright blue giants. These stars are very rare and very hot, exceeding 30,000 kelvin. (For context, the Sun has a temperature of about 5,800 kelvin.) Only about 1 in every 3 million stars in our neighborhood is a star of this type.

[cometsovcupid]

This particular nebula, located in the Constellation Ara nearly 4,000 light-years away, has a fantastic resemblance to a pair of fighting dragons . (I have seen it called the “Fighting Dragons of Ara” or the Fighting Dragon Nebula – but I haven’t seen that name used by any official organization). This nebula resides within the open cluster called NGC 6193, which is invisible to the naked eye and chiefly responsible for lighting up the contours of the ‘Fighting Dragons.’ #fightingdragons #ngc6193 #michaelsidonio http://ift.tt/2wExgpo

The Massive Star-Forming Regions Omnibus X-Ray Catalog, Third Installment. (arXiv:1907.13126v1 [astro-ph.HE])

We offer to the star formation community the third installment of the Massive Star-forming Regions (MSFRs) Omnibus X-ray Catalog (MOXC3), a compilation of X-ray point sources detected in 50 archival Chandra/ACIS observations of 14 Galactic MSFRs and surrounding fields. The MOXC3 MSFRs are NGC 2264, NGC 6193, RCW 108-IR, Aur OB1, DR15, NGC 6231, Berkeley 87, NGC 6357, AFGL 4029, h Per (NGC 869), NGC 281, Onsala 2S, G305, and RCW 49 (Wd 2); they have distances of 0.7 kpc to 4.2 kpc. Most exhibit clumped or clustered young stellar populations; several contain at least two distinct massive young stellar clusters. The total MOXC3 catalog includes 27,923 X-ray point sources. We take great care to identify even the faintest X-ray point sources across these fields. This allows us to remove this point source light, revealing diffuse X-ray structures that pervade and surround MSFRs, often generated by hot plasmas from massive star feedback. As we found in MOXC1 and MOXC2, diffuse X-ray emission is traceable in all MOXC3 MSFRs; here we perform spectral fitting to investigate the origins of selected diffuse regions. Once again, MOXC3 shows the value of high spatial resolution X-ray studies of MSFRs enabled by Chandra.
