    #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

    Pismis 24: The small open star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light-years away from Earth. The brightest object in the picture is designated Pismis 24-1. It was once thought to weigh as much as 200 to 300 solar masses. This would not only have made it by far the most massive known star in the galaxy, but would have put it considerably above the currently believed upper mass limit of about 150 solar masses for individual stars.
    However, Hubble Space Telescope high-resolution images of the star show that it is really two stars orbiting one another. They are estimated to each be 100 solar masses. Image released on Dec. 11, 2006

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.

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.

Two stars orbit one another in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light-years away from Earth.

This cosmic vista stretches 20 degrees across constellation Taurus. It begins at the Pleiades and ends at the Hyades, two of the best known star clusters in planet Earth's sky. On top, the lovely Pleiades star cluster is about 400 light-years away. In a familiar celestial scene, the cluster stars shine through dusty clouds that scatter blue starlight. At bottom, Hyades cluster looks more spread out compared to the compact Pleiades and lies much closer, 150 light-years distant. Beautiful! (NASA)
