An Einstein X-ray observation of NGC 5408, a small irregular galaxy undergoing a violent burst of star formation, reveals that it radiates about 10 to the 40th erg/s in 0.5-3keV X-rays. Such a high X-ray luminosity means that L(x)/L(v) is greater than 0.1. The low metal abundance of NGC 5408 may be an important factor and suggests that most young galaxies are X-ray luminous.
