Recent technological advances are opening up more of the night sky to astronomers, allowing them to follow events using multiple telescopes as the Earth rotates. Researchers hope that a higher frequency of rare extreme astrophysical events such as colliding neutron stars will be detected using the next-generation radio telescopes sited in Europe, South Africa and Western Australia. With the so-called 4 Pi Sky project, events can be tracked across the sky using this series of terrestrial telescopes. These events can then be further analyzed using orbiting X-ray telescopes and ground based optical telescopes. One of the grandest aims of the project is to provide answers to some of the largest remaining question in physics, such as the nature of gravity.
