Supermassive black hole appears to be firing a beam right at Earth

Astronomers have struggled to snap clear images of Sagittarius A* thanks to a "foggy cloud of hot gas" in the way, according to a new study.

But after linking telescopes across the world to make a "virtual telescope the size of the Earth", they've managed to narrow down the source of its radio emissions to a point so small - one 300 millionth of a degree - the most logical explanation is that it's being fired right at us.
