Unformatted text preview: The Telescope recently being used to get these images is called High Energy Replicated Optics short for HERO. They are using this by propelling a balloon above 99 percent of the earth’s atmosphere where the data being analyzed should be never before seen details of cosmic images. When we get these mirrors actually into space they will gather protons from some of the most violent objects in the universe including exploding stars and black holes.
