The lifetime of a massive star before it begins to deplete its nuclear fuel is less than 5 million years (1). In contrast, the age of the galaxy is more than 10 billion years (2); nevertheless, many massive and short-lived stars have been identified by observations at optical wavelengths. These massive stars must have formed very recently relative to the age of the galaxy, and therefore star formation must be occurring in the galaxy at the present time.
