An illustration of how a supermassive blackhole would make stars in the first 50 million years of the universe. The foreground shows stars in the making, gas clouds getting crushed by the black hole’s powerful magnetism. The background shows fully formed stars. A spiral of dust and gas revolving like a storm around the black hole also is shown. Also, the black hole shoots out plasma and energy upwards from the center of this storm.
