Star on a Hubble diet
Left: ACS WFC image of NGC 6357 with Pismis 24-1 in the centre (the brightest star). Middle: Looking closer at Pismis 24-1 with Hubble's ACS High Resolution Channel it becomes clear that it is in reality two stars.Right: ACS HRC image close-up showing the two stars of Pismis 24-1. It was thought to have an incredibly large mass of 200 to 300 solar masses. New NASA/ESA Hubble measurements of the star, have, however, resolved Pismis 24-1 into two separate stars, and, in doing so, have "halved" its mass to around 100 solar masses.
