Interplanetary Scintillation Array

The observatory's staff use sheep to keep grass away from the antennas because a lawn mower cannot fit in the spaces.

Antony Hewish designed the IPS Array to measure the high-frequency fluctuations of radio sources, originally for monitoring interplanetary scintillation.

Hewish received a Nobel Prize after the high time-resolution of the array allowed the detection of pulsars by Jocelyn Bell in 1967.

[1] The IPS Array has more recently been used to track and help forecast interplanetary weather, and specifically to monitor the solar wind.
