Cocoon Nebula : Star-forming nebula located about 2,500–4,000 light-years from Earth in the direction of the constellation Cygnus.
Red glow is produced by ionized hydrogen (H-alpha emission).
A hot, massive young star illuminates the surrounding gas and dust, causing it to glow.Dense clouds of dust weave through the nebula and block background starlight, creating dramatic contrast.
