NGC 3576, also known as the Liberty Nebula, and NGC 3603 are two regions within the Sagittarius arm of our galaxy where stars are actively being formed.
In NGC 3576, the intricate shapes are believed to be a result of star formation events. The swirling filaments are sculpted by the strong winds coming from the young, massive stars at the core of the nebula.
On the other hand, NGC 3603 stands out for hosting the most massive visible cloud of glowing gas and plasma in the Milky Way. The cluster of stars at its center is the densest collection of very massive stars found in our galaxy.
