Crazy, wrap your head around this one.
The most distant observable object found, an supernova that occurred 520 million years after the big bang.
It took the light to reach us 13.14 BILLION YEARS to reach our telescopes. How mind boggling is that!

The event, which was picked up by Swift in April 2009, is referred to by astronomers using the designation GRB 090429B.
The "GRB" stands for "gamma-ray burst" - a sudden pulse of very high-energy light that the telescope is tuned to find on the sky.
These bursts are usually associated with extremely violent processes, such as the end-of-life collapse of giant stars.
"It would have been a huge star, perhaps 30 times the mass of our Sun," said lead researcher Dr Antonino Cucchiara from the University of California, Berkeley.
"We do not have enough information to claim this was one of the so-called 'Population III" stars, which are the very first generation of stars in the Universe. But certainly we are in the earliest phases of star formation," he told BBC News.
Swift, as its name implies, has to act quickly to catch gamma-ray flashes because they will register for only a few minutes.
