Why Have a Telescope in Space?


NGC 3147 is a spiral galaxy 130 million light-years away from Earth. Hubble’s clear view of the cosmos enables it to capture details like the clusters of young blue stars, pinkish nebulae and lanes of dust visible in the galaxy’s graceful, winding arms. Due to the blurring effects of Earth’s atmosphere, ground-based telescopes are unable to achieve such resolution.
