Astronomers have created the world’s largest virtual optical telescope linking four telescopes in Chile, so that they operate as a single device. The telescopes of the Very Large Telescope (VLT) at the Paranal observatory form a virtual mirror of 130 metres in diameter. A previous attempt to link the telescopes last March failed. Thursday’s link-up was the system’s scientific verification – the final step before scientific work starts. Linking all four units of the VLT will give scientists a much more detailed look … Continue reading

Nothing sinister, but something a little bit dangerous. The device consists of two wires held close together. Beneath them is a device that will raise the electrical potential … Continue reading
