Lobster Nebula (NGC 6357), located in the Scorpio Constellation, about 5900 light years from Earth.
NGC 6357 is an emission nebula, full of young star clusters and dark dust, gases and protostars within their birth disks. It is a rich star-forming region.
Stellar winds, intense magnetic fields, gravity, and radiation pressure carve complex structures in gases and dust.
