No ticket required Program: For thousands of years, humans observed the night sky with their eyes. In the beginning of the 17th century, Galileo’s telescopes revolutionized our knowledge of the Universe. With the advent of rockets in the mid-20th century, it became possible to go above the atmosphere and observe X-ray and gamma ray radiation from the hot and violent Universe. But it is not only light that can give us information about the cosmos - neutrinos and cosmic rays also provide vital information. Finally, the detection by the LIGO experiment of gravitational waves from two merging black holes opened a new window in astrophysics. Run time: 29 minutes. Recommended Ages: 10 and up. Directions: Enter the campus using Research Way from York Road. The Science Complex is on the right.
