SKA overview: what the project is

Please join my mailing list here 👉 https://briankeating.com/yt for your chance to win a meteorite 💥 What connects a 5,000-year-old stone circle to the most ambitious radio telescope ever built? In this episode, we travel from Stonehenge to Jodrell Bank and the Square Kilometre Array (SKA) to trace humanity’s obsession with the sky — from lifting megaliths to catching whispers of the Big Bang.

We start at Stonehenge, a Neolithic “star clock” aligned with the solstices, then fast-forward through millennia to stand beneath the 76 m Lovell Telescope at Jodrell Bank, and finally into the control rooms of the SKA: hundreds of dishes and over 100,000 antennas designed to detect the first stars and galaxies. The tools change — stones, steel, superconducting detectors — but the question stays the same: what is our place in the universe?

Topics:

* How Neolithic builders engineered and aligned Stonehenge with the Sun?

* Why Jodrell Bank became a Cold War–era listening post and a pulsar powerhouse?

* How pulsars, neutron stars, and the Crab Nebula became cosmic calibration tools?

* What the SKA will actually “hear” from the cosmic Dark Ages and first stars?

* How the Simons Observatory and SKA together will rewrite our map of the cosmos
