stardust and gas form the raw materials for new stars and planetary systems. exploding stars also release large amounts of high energy particles known as cosmic rays atomic particles that are holed into space at almost the speed of light. but there's a problem with finding out more about cosmic rays telescopes such as those in color auto can track the light that comes from stars light is energy in the form of photons humans can also observe this optical spectral range on a limited scale. most telescopes built in the twentieth century contract photons some examine visible or infrared light. well as long way of radiation such as radio waves or short wave radiation such as x. rays the better for all their sophistication none of these telescopes can detect
