Most distant black hole weighed
The mass of the most distant black hole yet known has been determined. It weighs in at one quadrillion (1,000,000,000,000,000) times that of the Earth.
Put another way, it is the mass of three billion Suns.
This huge number is not unusual for a black hole but what is surprising is that such a massive structure formed so early in the history of the Universe.
It is 13 billion light-years away from Earth, so what we are seeing now gives a picture of the Universe when it was very youthful.
