About this Image

Radio imaging with the Very Large Array captures newborn massive star clusters as they emerge from their birth material in the galaxy NGC 4449. These "super star clusters" contain tens to hundreds of thousands of stars. The young stars produce hot ionized gas which is detectable at radio wavelengths, shown in blue here. An image from the Hubble Space Telescope shows the visible starlight in yellow.
