Radio-astronomers form telescope the size of Earth

17 radio telescopes around the world will join forces this week to carry out a unique observation of three quasars, distant galaxies powered by super-massive black holes at their cores, achieving images with up to one hundred times better resolution than those available from the best optical telescopes.
Using an astronomical technique called electronic, real-time Very Long Baseline Interferometry, or e-VLBI, participating telescopes will observe the same object simultaneously. Data from each telescope will be streamed across the globe through high-speed optical networks to a purpose-built supercomputer at JIVE in the Netherlands.
