In the next 24 hours, 35 telescopes on all seven continents will be linked to listen to 243 specific quasars. The point is to establish a baseline for further observations, since the quasars are stationary in the night sky, and provide a good basis for mapping.

The last time this attempted, the total number of 23 telescopes were used. These quasars are also used to set up the GPS system.
