Scientists just spotted the farthest individual star ever spotted - a blue supergiant 9 billion light-years from Earth. Even with the most powerful telescopes out there, it is basically impossible to spot things further than 100 million light-years away. But thanks to a phenomenon called gravitational lensing, astronomers examining a faraway supernova were able to spot a point of light that turned out to be a star. Gravitational lensing occurs when the rays of light coming into a lens are...
