astronomicalwonders:An Emission Nebula - NGC 6357Far away in the constellation Scorpius, inside the core of the large emission nebula NGC 6357, lies the star cluster Pismis 24. Part of the nebula is ionised by the youngest stars in Pismis 24 - which are characterized by their blue light. 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 for Astronomers.Credit: NASA/ESA/Hubble -- source link
