Astronomers discover supermassive black hole at the heart of ancient galaxy

<p>Astronomers have spotted a massive disk galaxy, that formed 12.5 billion years ago when our 13.8 billion-year-old universe was only a tenth of its current age.</p>

<p>According to the information provided by the astronomers, the galaxy’s disk has a mass of 70 billion times that of our sun. It’s also rotating at 170 miles per second, which is similar to our Milky Way galaxy.</p>
