"Star Trails over One-Mile Radio Telescope"


🏗️ Built in 1964 by the University of Cambridge, it's located at the Mullard Radio Astronomy Observatory in England.

📏 As the name suggests, its baseline spans one mile, using three 18-meter dishes.

🌌 It was designed for interferometry, combining signals from multiple dishes to study radio sources in deep space.

🧠 Played a key role in mapping radio galaxies and understanding quasars.

🛰️ Though retired, it helped pave the way for modern radio astronomy and large-scale sky surveys.
