The Lobster Nebula is located in the Constellation of the Scorpion, is approximately 60 minutes in diameter and consists of HII regions, high mass stars (O and B), photodiodes regions and infrared sources.
The elegant structures it exhibits, result from interactions between stellar winds, magnetic fields, radiation pressure and gravity, and the brightness resulting from the emission of ionized hydrogen.
The central, bubble-like region is separated by a column of dust that divides the region into two wells and exhibits diffuse emissions of OIII revealing that it is filled by hot gas (10^4 K), with the agglomerate Pismis 24 being the main source of excitation in this region.
Pismis 24-1, also known as HD 319718, is the brightest star of the open cluster Pismis 24. It was once thought to be the most massive star known, but is composed of at least three individual objects, each still among the most luminous and most massive stars known.
