For thousands of years humans observed light coming from the night sky. The invention of the telescope revolutionized our knowledge of the Universe. In the 20th century it became possible to go above the earth’s atmosphere and observe X-ray and gamma ray radiation. The detection by the LIGO experiment of gravitational waves from two merging black holes opened a new window in astrophysics. This video presents images of the cosmos as revealed by all these different messengers.
