M7 C' o2 Y t3 |6 `The 'colossal' radio telescope that can see more of the universe than ever before (and could even find alien life)
Australia Square Kilometre Array Pathfinder is made up of with an array of 36 antennas each 12 meters (40 feet) across
is also the first building block in the world's largest telescope, the Square Kilometre Array (SKA) which will be based in both Australia and South Africa
