Deep inside the turmoil of the Cygnus X region, gas clouds fragment and collapse to form newborn stars. This 650-light-year-wide molecular cloud complex, shown here in a false-color, infrared image captured by NASA's Spitzer Space Telescope, contains three million solar masses of gas and dust and is home to thousands of dense, dusty cores that will eventually become stars. To find out more about the connection between these cores and the stars that they birth, see our AAS Nova highlight and the corresponding research article in the Astrophysical Journal Letters.
