GUM 37 The Southern Tadpole Nebula, also known as RCW 54c, is a celestial object located in the constellation Carina. It's classified as a diffuse HII emission region, essentially a vast cloud of ionized hydrogen gas.
Its most distinctive feature is the "Southern Tadpoles," a group of dark nebulae that resemble tadpoles. These dark regions are actually dense pockets of gas and dust within the larger emission nebula.
GUM 37 is a stellar nursery, where new stars are born from the collapsing gas and dust. The intense radiation from the nearby NGC 3572 star cluster is ionizing the hydrogen gas in GUM 37, causing it to glow.
