Eclectic Astronomer - A Chat With Cliff Stoll

Season 5 · Episode 3

Wednesday, October 29, 2025 • Duration 51:54

Br. Guy Consolmagno chats with Cliff Stoll - astronomer, teacher and author of the book The Cuckoo’s Egg, which tells the story of how he tracked down a group of German hackers working for the Soviet KGB in 1986. Cliff is also a long-time buddy of Br. Guy.

Co-Hosts:
Br. Guy Consolmagno SJ: Director of Vatican Observatory and President of the Vatican Observatory Foundation.
Bob Trembley: Factotum for the Vatican Observatory Foundation.

Guest:
Cliff Stoll is an astronomer, author, and teacher known for tracking down a group of German hackers working for the Soviet KGB in 1986.

As a systems administrator at Lawrence Berkeley National Laboratory, while working on the development of the Keck Telescope, Stoll pursued a 75-cent accounting hiccup, ultimately uncovering a major security breach. His book, The Cuckoo’s Egg, details this investigation and became a bestseller.

The 1990 PBS NOVA video: The KGB, The Computer and Me – The Cuckoo’s Egg Story is available on a couple channels on YouTube – it’s hilarious!

Stoll’s work significantly contributed to early cybersecurity awareness.

Stoll is also known for creating and selling glass Klein bottles

Sketcher of the Skies

Season 3 · Episode 1

Monday, January 2, 2023 • Duration 40:04

What spurs an artist to start sketching celestial objects as they look in her small telescope? What thrills her the most? Is it seeing the fine details of nebulae through large telescopes? Sketching the Moon's slowly changing terminator and Sun's prominences? Working with children - helping them understand the night sky, and awakening their curiosity in science?

Deirdre Kelleghan is an astronomical artist, living in western Ireland, under incredibly dark skies. With an eye to the telescope, she sketches the beauty of the cosmos, and through her outreach, she teaches others how to do the same.

Deirdre is a former President of the Irish Astronomical Society, and is the current Outreach / Vice Chair of the Irish Federation of Astronomical Societies; she has been interviewed on TV, radio and podcasts about her outreach activities. She is also a Sacred Space Astronomy author, and frequently posts her artwork on the Vatican Observatory website.

Guests:
- Deirdre Kelleghan: Astronomer, astronomical artist, educator and Sacred Space Astronomy author.
- Br. Guy Consolmagno SJ: Director of Vatican Observatory and President of the Vatican Observatory Foundation.

From Voyager to Webb: Heidi Hammel and the Ice Giants

Season 2 · Episode 7

Tuesday, October 25, 2022 • Duration 47:39

So, how many people do you know who have had a children’s book written about them? Dr. Heidi Hammel gained international fame in 1994 by leading the Hubble Space Telescope Team that imaged Jupiter during the impacts of Comet Shoemaker Levy 9, but in fact her main research has focused on the “ice giant” planets, Uranus and Neptune. Her ground-based telescope observations were crucial to interpreting the Voyager spacecraft flyby images, and she now helps direct planetary observations with the Webb Space Telescope.

Guests:
Dr. Heidi Hammel - Vice President for Science for the Association of Universities for Research in Astronomy (AURA), and an Interdisciplinary Scientist for the James Webb Space Telescope.
- Br. Guy Consolmagno SJ - Director of Vatican Observatory and President of the Vatican Observatory Foundation.
