In this week's questions show, I explain why we'll never know which stars have no planets. How we could prevent a catastrophe to Earth, and why aliens might still be a threat to us.

Episode 578: Open Space 49: How Can Planets Capture Asteroids? And More...

No guest this week, just a live QA with me and the audience about all things space and astronomy. People had questions about how planets can capture asteroids to turn them into moons, what rocket James Webb will use to fly to space, and why you can't use antimatter to destroy a black hole. 05:45 How can a planet capture an asteroid? 07:21 Why are quasars so far from us? 09:26 How could you make a black hole of photons? 11:25 Would I rather live a year on the Moon or Mars? 12:46 What will JWST launch on 14:08 What's the limit on a planet's mass for rocketry? 17:06 Do I prefer to observe alone? 18:55 Why doesn't antimatter destroy black holes? 20:43 Will we get space engines from The Expanse? 24:05 Shouldn't we solve our problems here on Earth? 26:30 What happens to us when the Sun dies? 28:28 Why aren't there video cameras on Mars? 30:00 How do we learn about what things are made of with radio waves? 32:00 Are there any metals in space that can't find on Earth? 33:12 How do we measure distances to stars? 35:16 EMDrive 36:23 Are metals precious to the planet you're on 37:05 Will Skylon fly? 38:35 Cyanogen gas in comets 39:12 Talking to people who don't care about space 41:00 How do planets start forming? 41:48 What do I think of antimatter rockets? 43:09 Could we build an arm to lift us to space? 43:32 Should we just colonize space itself? 44:20 Is Planet 9 a black hole? 50:11 Does Canada have radio telescopes? 50:50 When will a black hole turn into regular matter again? 51:30 Wildlife on Vancouver Island 53:13 Could breakthrough starshot work to redirect asteroids? 54:25 Could we see life on Alpha Centauri? 57:00 Is Alpha Centauri visible from the North? 57:30 Would generation ships work?

Episode 577: AstroClipper: Plans For A Two-Stage, Fully Reusable Spaceplane

Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earth’s atmosphere. Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earth’s atmosphere again. Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane? Exodus Space Corporation has been secretly working on this concept for a decade now, and what they’re proposing is pretty revolutionary.

Episode 576: What Comes After LUVOIR? Three Extreme Ideas For Space Telescopes

While we’re all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved. (Please get approved, please get approved.) We’re going to need a way to pass the time. So let’s have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes. Unless you’ve been crawling through scientific journals like me, I guarantee you’ve never heard of any of them. But when I’m done, you’re going to want to fund all of them.

Episode 574: Venus Could Have Supported Life For Billions Of Years. First Habitable Planet In The Solar System?

After decades of research, including multiple landers and orbiters, science can definitively say: Venus sucks. Seriously, that place is the worst, with its boiling temperature, intense pressure, sulfuric acid rain, and more. But was it always this bad? According to new research from NASA and various universities in Sweden and the US, Venus might have actually been the first habitable world in the Solar System. And it might have maintained a reasonable climate for billions of years, finally rolling over into a runaway greenhouse effect just a few hundred million years ago.

Episode 573: Open Space 48: Floating in Darkness with Astronaut Ron Garan

This week I was joined by astronaut Ron Garan to talk about his new book "Floating in Darkness". Ron is an accomplished F-16 pilot, flying combat missions during Desert Shield and Desert Storm. He flew to space twice, first aboard STS-124, and then a six-month stay on board the International Space Station as part of Expedition 27.

Episode 571: Starship Takes Shape. Are We Months Away From A Fully Reusable Rocket System?

On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel. As part of his presentation, Musk showed off the history of the company’s developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when they’re fully operational. It was actually a pretty short presentation, and there weren’t a lot of details. But he stuck around to answer questions from many space journalists, and we’ve got a much better idea about Starship and what happens next.

Episode 570: What Will It Take To Feed A Million People On Mars?

In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects it’ll take to create a self-sustaining civilization. The number of details in an effort like this is mind-boggling. What about the reduced gravity, radiation exposure, and space madness? What about return flights? Replacement parts? Building materials? What’s everyone going to eat?

Episode 575: Q&A 102: Will Starship Cause Global Warming? And More... Featuring Tony Darnell from Deep Astronomy

In this week's questions show, I explain why Starship probably won't contribute to human carbon emissions, if there's a galactic Prime Directive, and if SpaceX has finally perfected the single-stage to orbit.

Episode 574: Venus Could Have Supported Life For Billions Of Years. First Habitable Planet In The Solar System?

After decades of research, including multiple landers and orbiters, science can definitively say: Venus sucks. Seriously, that place is the worst, with its boiling temperature, intense pressure, sulfuric acid rain, and more. But was it always this bad? According to new research from NASA and various universities in Sweden and the US, Venus might have actually been the first habitable world in the Solar System. And it might have maintained a reasonable climate for billions of years, finally rolling over into a runaway greenhouse effect just a few hundred million years ago.

Episode 573: Open Space 48: Floating in Darkness with Astronaut Ron Garan

This week I was joined by astronaut Ron Garan to talk about his new book "Floating in Darkness". Ron is an accomplished F-16 pilot, flying combat missions during Desert Shield and Desert Storm. He flew to space twice, first aboard STS-124, and then a six-month stay on board the International Space Station as part of Expedition 27.

Episode 571: Starship Takes Shape. Are We Months Away From A Fully Reusable Rocket System?

On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel. As part of his presentation, Musk showed off the history of the company’s developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when they’re fully operational. It was actually a pretty short presentation, and there weren’t a lot of details. But he stuck around to answer questions from many space journalists, and we’ve got a much better idea about Starship and what happens next.

Episode 570: What Will It Take To Feed A Million People On Mars?

In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects it’ll take to create a self-sustaining civilization. The number of details in an effort like this is mind-boggling. What about the reduced gravity, radiation exposure, and space madness? What about return flights? Replacement parts? Building materials? What’s everyone going to eat?
