Another human-made marvel is the Hubble Space Telescope, which holds the Guinness World Record for being the most expensive telescope in the world sitting at $2.1 billion. It was launched into space back in April of 1990 and since it’s dispatch into space, it has also been responsible for a number of amazing discoveries like dark matter, Pluto’s two moons, dark energy and black holes. Pretty cool, even if you aren’t a scientist.
