Ep. 770: The Ethics of Mars Exploration

Season 19 · Episode 770

Monday, November 10, 2025 • Duration 41:51

Astronomy Cast Ep. 770: The Ethics of Mars Exploration By Fraser Cain & Dr. Pamela Gay Streamed live on Nov 3, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay. It is arguable that humanity now has the technological ability to live on Mars. It would be done at enormous expense and sacrifice, and there are some tricky problems that we haven't solved yet. Although we could live on Mars, should we? There is a famous quote from Jurassic Park: "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." This concept is played out across the sciences, and in planetary exploration, it requires us to ask, all because we can launch humans toward Mars, should we?

Ep. 769: Little Red Dots

Season 19 · Episode 769

Monday, October 27, 2025 • Duration 30:40

Astronomy Cast Ep. 769: Little Red Dots By Fraser Cain & Dr. Pamela Gay Streamed live on Oct 20, 2025. New instruments bring new mysteries, and when James Webb came on line it uncovered a collection of strange, compact, bright objects shifted deeply into the red end of the spectrum. These were dubbed "Little red dots" or LRDs. And the astronomical community continues to puzzle over what they are. When JWST first peered into the distant past, it discovered the early universe had a rash of little red dots. Their existence just 450 million years after the big bang meant either galaxies were forming way faster than anyone predicted, or something unimagined had been found.
