( CNN) Each time a brand-new telescope has been turned on, we have learned something fundamental about our cosmo.
Galileo’s first telescope visualized the moons of Jupiter and perpetually destroyed the idea that the Earth was at the center of the universe. Edwin Hubble expended the Mount Wilson Observatory in 1917 to show that other galaxies exist and that the Milky way was but one of many.
The Vela planets orbiting the Dirt in the 1960 s were designed to see the gamma rays that accompany a nuclear explosion. They worked for that role, but they likewise discovered gamma ray flares from seat, which was eventually identified as the explosion of a idol so murderous that they could be seen across the entire cosmo.
