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.

Pismis located at the core of small open star cluster Pismis can be seen in this image provided by NASA and ESA. The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 that extends on the arm of the Sagittarius constellation.
