  • Fantastic

    These episodes are the perfect length, have interesting topics and are mixed with some light humor. The fact that there are no advertisements makes it my go to podcast. Entertaining and informative from a guy that sounds like someone I would enjoy hanging out with.

Talking Points

Recent interactions between the hosts and their guests.

382.1 The (un)likelihood of meeting aliens - 31 August 2026
Q: Dear Cheap Astronomy, What is the likelihood that we'll ever meet aliens?
The host argues that meeting aliens is highly unlikely due to immense distances, environmental mismatches, and travel hazards; if any contact occurs, robots are the more probable emissaries, and any meeting would likely be incidental rather than planned, with media hype and economic incentives following such an event.
379. Dear Cheap Astronomy - Episode 148 - 20 July 2026
Q: Dear Cheap Astronomy, just how dangerous are cosmic rays?
Cosmic rays are high-energy particles that create atmospheric showers; they pose radiation risks to astronauts, especially beyond the magnetosphere, and shielding must address both primary particles and secondary radiations.
379. Dear Cheap Astronomy - Episode 148 - 20 July 2026
Q: Dear Cheap Astronomy, How big is the solar system?
The host explains that there isn't a single fixed size; the solar system's extent depends on the definition used, such as the heliopause or the Oort Cloud, with practical boundaries like the heliopause around 18 billion kilometers and the Oort Cloud extending much further.
378.1 Goldilocks Zones and the Cosmic Shoreline - 13 July 2026
Q: Dear Cheap Astronomy, what's the difference between the Goldilocks Zone and the Cosmic Shoreline?
The Goldilocks Zone centers on having temperatures suitable for liquid water, focusing on stellar output and orbital distance, but it doesn't guarantee an atmosphere or water stability because atmospheric pressure and protective magnetic effects also matter. The Cosmic Shoreline, based on a 2017 framework, emphasizes whether a planet can retain an atmosphere by considering escape velocity and the incoming stellar flux, offering a more binary yes/no division regarding atmospheres and potential water, though it also has caveats.
377. Dear Cheap Astronomy - Episode 146 - 22 June 2026
Q: What is the current status of planetary defense and how confident are scientists about long-term risks?
Scientists are actively tracking near-Earth objects with extensive international coordination, and while the immediate risk appears low, there is acknowledgment of unknown objects and long-term probabilities that keep planetary defense as a high-priority, ongoing effort.
