Feature Guests: Hilton Lewis


The twin Keck Telescopes of Hawaii are the world’s largest optical and infrared telescopes. For twenty five years they have turned their eyes on the farthest and faintest objects in the cosmos, stacking up a dizzying array of accomplishments: from evidence for the supermassive black hole at the centre of our own galaxy to a recent discovery of the most distant galaxy in the observable universe.

Today Keck Observatory Director Hilton Lewis joins Justin Trottier at The Star Spot to discuss the life of the most impactful telescope astronomers possess, and to speculate on the future of the Keck in the emerging intensely competitive era of giant telescope astronomy.

Humans have the inate ability to self repair. Now Anuj tell us that the advent of self healing spacecraft may be close at hand. Comets are the ultimate fear factor. But while comets do have the ability to take life, Tony tells us they may also have the power to give it. And Dave reports on the closest known quasar, the product of the battle of two cosmological giants.

About Our Guest

The career of Hilton Lewis has grown alongside that of the Keck observatory. Lewis has been a member of the Keck team since the project’s launch in 1986. From his original job designing and developing the software that controls the Keck he would be promoted to many senior positions, then appointed Deputy Director in 2002 and Director in 2014. Lewis earned a degree in Electrical Engineering from the University of Cape Town and an MBA from the University of Hawai’i at Manoa.
