I was trawling through the internet as one does at times and came across the Hubble image of NGC 6357 in Scorpio. In the centre of this nebula there is a cluster of stars, a member of which was thought to have a mass of 200 - 300X the sun
. Close scrutiny by HST has however revealed that it is indeed a double star so each member is
only of the order of 100 - 150 solar masses, still...imagine being 1 AU from these stars
I knew I had taken a shot of this area just this season so I zoooooooomed in and found them -
HERE - this field is only a few arc min across.
You can follow the links under the image to read more about these big stars.
