In this week's live questions show, I explain why planets can remain habitable long after their stars have died, what we're going to do now that Arecibo has collapsed, how we'll explore the oceans underneath Europa. I also answer the question of whether or not I'm ready to learn about the secret Galactic Federation.Our live shows are provided ad-free thanks to the support of our amazing patrons.

My guest this week is Alex Ignatiev, from Lunar Resources. Alex and his team are working on a rover that could build solar panels, wiring and even radio antennae out of lunar regolith. This could support future bases or even radio telescopes.You can learn more about Lunar Resources here:http://lunarresources.space/Our Book is out!https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1GWeekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/Astronomy Cast:https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSgSupport us at: https://www.patreon.com/universetodayMore stories at: https://www.universetoday.com/Twitch: https://twitch.tv/fcainFollow us on Twitter: @universetodayLike us on Facebook: https://www.facebook.com/universetodayInstagram - https://instagram.com/universetodayTeam: Fraser Cain - @fcain / frasercain@gmail.comKarla Thompson - @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comSupport Universe Today Podcast

In this week's Open Space, we had a series of questions about the International Space Station. How long will it remain in orbit, and what role will it continue to play with other space stations under construction? We also talked about how much longer the Earth will remain habitable, and if it could be possible to replace Arecibo.00:00:00 Start00:03:35 How much longer with the Earth be habitable?00:06:30 The great conjunction00:09:11 Is nuclear power a good option in space?00:13:31 What is the future of the ISS?00:18:24 What are the chances of replacing Arecibo?00:21:57 Couldn't we melt down the station for raw material?00:23:35 What do I think of Axiom's private space station?00:27:28 What's the best supernova candidate?00:32:25 Could we add mass to Mars to restart its core?00:36:03 Am I excited about the next Gaia release?00:40:45 Are we looking backwards in time?00:42:00 How's Chinese going?00:46:39 What's the future of the Thirty Meter Telescope?00:50:24 Will there be more international collaboration?00:54:45 How much of the Universe has already disappeared?00:56:33 Future telescope names?00:57:00 Legit warp drive?00:59:45 Any value putting a telescope on Mars?Our Book is out!https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/Audio Podcast version:ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2RSS: https://www.universetoday.com/audioWhat Fraser's Watching Playlist:https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1GWeekly email newsletter:https://www.universetoday.com/newsletterWeekly Space Hangout:https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/Astronomy Cast:https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSgSupport us at: https://www.patreon.com/universetodayMore stories at: https://www.universetoday.com/Twitch: https://twitch.tv/fcainFollow us on Twitter: @universetodayLike us on Facebook: https://www.facebook.com/universetodayInstagram - https://instagram.com/universetodayTeam: Fraser Cain - @fcain / frasercain@gmail.comKarla Thompson - @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fwChad Weber - weber.chad@gmail.comSupport Universe Today Podcast
