The Square Kilometre Array
) Organisation recently announced a two site
approach, in Australia-NZ and Southern Africa
, a move that was applauded
by the Australian
team. Once fully operational
in 2024, SKA's one square kilometre collecting area
should lead to major advances
- The data collected by the SKA in a single day would take nearly two million years to playback on an ipod.
- The SKA central computer will have the processing power of about one hundred million PCs.
- The SKA will use enough optical fibre to wrap twice around the Earth!
- The dishes of the SKA will produce 10 times the global internet traffic.
- The aperture arrays in the SKA could produce more than 100 times the global internet traffic.
- The SKA will generate enough raw data to fill 15 million 64 GB iPods every day!
- The SKA super computer will perform 10^18 operations per second – equivalent to the number of stars in three million Milky Way galaxies – in order to process all the data that the SKA will produce.
- The SKA will be so sensitive that it will be able to detect an airport radar on a planet 50 light years away.
- The SKA will contain thousands of antennas with a combined collecting area of about one square kilometre (that’s 1,000,000 square metres!).
