This is an image of NGC 6357, also known as the Lobster Nebula, taken with narrowband filters and processed using the Hubble palette. Although known as the Lobster nebula, the FOV of this image is too small to see the entire nebula. It lies about 8,000 light years away in the constellation Scorpius. This nebula is home to open star cluster Pismis 24, which has some of the most unusually bright and massive stars in the galaxy. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity.
Comments and suggestions appreciated.
