Making Stars in NGC 4449
Radio imaging with the Very Large Array (VLA) 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 red here. An image from the Sloan Digital Sky Survey shows the visible starlight in gold.
