🌌 Monkey Head Nebula (NGC 2174)
A vast cloud of gas and dust in Orion where new stars are forming. The glow comes from hot young stars within the nebula that energize the gas, giving us red from hydrogen and bluish tones from oxygen. Its shape looks like a monkey’s face, which is why it is called the Monkey Head.
