Interplanetary Scintillation Array, Radio telescope at Mullard Radio Astronomy Observatory, Cambridge, England.
The Interplanetary Scintillation Array contains 4,096 dipole antennas arranged in a phased configuration across multiple acres of grassland.
Constructed in 1967 at the Mullard Radio Astronomy Observatory, this telescope led to the groundbreaking discovery of the first pulsar that same year.
The telescope represents a milestone in radio astronomy research, leading to the Nobel Prize in Physics for scientist Antony Hewish.
The telescope operates at a radio frequency of 81.5 MHz and can complete a full mapping of the northern sky within 24 hours.
Sheep maintain the grass around the antennas because standard lawn mowers cannot navigate between the closely spaced equipment.
