80 telescopes. 24 hours. One world.

U. CHICAGO (US)—“Around the World in 80 Telescopes” is a live 24-hour webcast, following night and day around the globe to some of the most advanced observatories both on and off the planet. The webcasts start Friday, April 3, in Hawaii, then move around the world.

The effort is part of the 100 Hours of Astronomy project, which consists of more than 1,500 public outreach events in more than 130 countries from April 2 to 5.

The South Pole Telescope (SPT), which the University of Chicago operates with eight partner organizations, will be among the observatories taking part. The South Pole live webcast is scheduled to begin at 2:25 a.m. CDT Saturday, April 4.

Taking advantage of the exceptionally clear, dry, and stable atmosphere
at the South Pole, the 10-meter SPT (http://pole.uchicago.edu/) is mapping large areas of sky for clues about the mysterious phenomenon know as dark energy. A repulsive force, dark energy pushes the universe apart and overwhelms gravity, the attractive force that all matter exerts.

Other participants in Around the World in 80 Telescopes include Gemini North and Keck in Hawaii, the Anglo-Australian Telescope, telescopes in the Canary Islands, the South African Large Telescope, Chilean observatories such as the Magellan Telescope at Las Campanas Observatory, and the Hubble Space Telescope.
