Space Shot of the Day: Cathedral to Massive Stars The Hubble Space Telescope took this spellbinding image of Pismis 24 (shown center above), one of the most massive and luminous star clusters known, glimmering above the NGC 6357 nebula that is approximately 8150 light-years away. According to NASA’s estimates, the brightest star of Pismis 24 cluster is over 200 times the mass of our Sun. Space Shot of the Day is a feature series following the latest developments in planetary science, ...
The small open star cluster Pismis 24 contains extremely massive stars. The brightest object in the picture was once thought to weigh as much as 200 to 300 solar masses. This would have made it by far the most massive known star in the galaxy, and put it considerably above the currently believed upper mass limit of about 150 solar masses for individual stars. However, Hubble images show that it is really two stars, each 100 solar masses, orbiting one another. More here: http://buff.ly/1s36aP2

#NASA/#ESA/#Hubble Heritage | #Star on a Hubble diet: The star cluster Pismis 24 lies in the core of the large emission #nebula NGC 6357 that extends one degree on the sky in the direction of the Scorpius constellation. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder. #cosmos #universe
#Astronomy: Star on a #Hubble diet. The star cluster #Pismis 24 lies in the core of the large emission nebula #NGC6357 that extends one degree on the sky in the direction of the Scorpius constellation. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder
What a beautiful image. It speaks volumes not only of space, but of the wonders and beauty of our universe. It speaks to our uncanny ability for awe.
Astronomy, i loved taking Mr. Smiths Astronomy class when i was in high school, still love looking at the stars

NGC 6357: Cathedral to Massive Stars Image Credit: NASA, ESA and Jesús Maíz Apellániz (IAA, Spain) Explanation: How massive can a normal star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, nearly making it the record holder.

Stunning. I would go there now if I could.
Images from Hubble Space Telescope. Star cluster Pismis 24 hangs over the dusty clouds of NGC 6357, a nebula about 8000 light-years away in the constellation Scorpius. This picture showed that the brightest star in the cluster is in fact two stars in a tight binary orbit. Each star is about a hundred times the Sun's mass.
Astronomy must-sees for
NGC 6357 - The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars. This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance. They said that in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull.[
Originally, the word “nebula” referred to almost any extended astronomical object (other than planets and comets). The etymological root of ...
