Title: Radio Astronomy Past, Present and Future:
Pushing Technology Forward
Abstract:
Radio Astronomy began with the discovery of cosmic radio signals
by Karl Jansky in the early 1930's, and has greatly changed our
view of the Universe. It was early realized that groups of radio
telescopes could be used together to reveal finer detail in radio
images of astronomical objects - a technique called radio interferometry.
Very Long Baseline Interferometry can obtain resolutions 50-100 times
better than the Hubble Space Telescope achieves. Today, radio astronomy is
undergoing a technological revolution, with data sent from telescopes to
processing centres along optic fibres at enormous rates of up to 30
Gbit/sec. Current developments are pushing toward the Square Kilometre
Array - an international radio telescope with unprecedented high
sensitivity planned to be finished in 2025.
