The galaxy NGC 4526 seems to hover serenely in space, a halo radiating an ethereal light. But at its center there is a rapidly spinning disk of gas moving at more than 155 miles per second.
The galaxy is in the Virgo cluster of galaxies, about 65 million light years away from Earth. Scientists know that NGC 4526 has hosted two supernova explosions in the past 45 years and has a supermassive black hole at its center that has the mass of 450 million suns.
