loose cluster of stars some 4,700 light-years from Earth in the constellation Cygnus. This clump of gas and dust has given birth to protostars, which represent the earliest steps in building a star. The glowing yellow one in the "head" is the most luminous and massive. Nearby stars firing ultraviolet radiation at IRAS 20324+4057 creates the intense blue glow, which also sculpts its tail into a long, wiggly shape. This clump stretches roughly a light-year from head to tail-tip, and contains gas weighing almost four times the mass of the sun.
