I’d say half the astronomy-related videos on YouTube are all about black holes. Clearly, they’re a fascinating topic, but they’re also a mystery. How do you observe something that can absorb all the radiation and matter falling onto them, and nothing can ever escape? How do we know they’re really there, and what are the best observations we can make?Today I’m joined by Dr. Paul Sutter, a cosmologist, and astrophysicist to talk about how we know black holes are really there and not just a figment of an astrophysicist’s imagination?Paul's Channel: https://www.youtube.com/channel/UCBr7XOxxQyBHEwqkhoci7vwPaul's new book:http://www.pmsutter.com/bookThumbnail credit: ESOOur 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/audioWeekly 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/fcainTwitter: https://twitter.com/universetodayFacebook: 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

On Sunday, May 31st, 2020, a SpaceX Crew Dragon capsule carrying astronauts Robert Behnken and Douglas Hurley docked with the International Space Station. This was a tremendous accomplishment for SpaceX and NASA, giving the United States the capability of launching its own astronauts, and no longer relying on its Russian partners.This was the 5th time that US astronauts went into orbit on a new kind of space vehicle, following in the footsteps of Mercury, Gemini, Apollo, and the Space Shuttle.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/audioWeekly 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/fcainTwitter: https://twitter.com/universetodayFacebook: 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.comReferences:https://www.nasa.gov/specials/ccp-press-kit/main.htmlhttps://blogs.nasa.gov/commercialcrew/2020/05/27/historic-launch-pad-39a/https://blogs.nasa.gov/commercialcrew/2020/05/31/international-space-station-welcomes-first-spacex-crew-dragon-with-nasa-astronauts/https://www.space.com/2811-nasa-places-500-million-bet-firms.htmlhttps://www.nasa.gov/exploration/news/COTS_selection.htmlhttps://arstechnica.com/science/2020/05/the-trampoline-is-working-spacex-returns-human-spaceflight-to-america/https://www.nasa.gov/specials/ccp-press-kit/dm1.htmlhttps://blogs.nasa.gov/commercialcrew/2019/12/https://www.nasa.gov/exploration/commercial/crew/index.htmlhttps://spaceadventures.com/space-adventures-announces-agreement-with-spacex-to-launch-private-citizens-on-the-crew-dragon-spacecraft/https://www.universetoday.com/144791/nasa-is-going-to-add-a-commercial-module-to-the-space-station/https://blogs.nasa.gov/commercialcrew/2020/04/06/boeing-to-fly-second-uncrewed-orbital-flight-test-for-nasa/Support Universe Today Podcast

When you’re out in space, water is the most precious resource you can get your hands on. It can be used for air, water, to grow food, radiation shielding, and most importantly, as the propellant for your spacecraft.Exploration of the Moon has revealed that there’s a tremendous amount of water ice locked into the regolith, but it’s probably very difficult to access. But there are also permanently shadowed craters at the Moon’s poles that could have more than enough water to support a permanently inhabitable station on the Moon.But it’s going to be tricky to get at, considering the fact that temperatures in the shadows plunge to -240 degrees Celsius, just 30 degrees above absolute zero.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/audioWeekly 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/fcainTwitter: https://twitter.com/universetodayFacebook: 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.comReferences:https://theprint.in/science/discovery-of-water-on-moon-what-indias-first-chandrayaan-mission-achieved-a-decade-ago/317591/https://www.nasa.gov/feature/ames/ice-confirmed-at-the-moon-s-poleshttps://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/chang-e-4https://spaceflightnow.com/2020/01/06/china-publishes-change-4-data-one-year-after-first-landing-on-far-side-of-the-moon/https://www.nasa.gov/feature/jpl/nasa-cubesat-will-shine-a-laser-light-on-the-moons-darkest-cratershttps://www.jpl.nasa.gov/missions/lunar-flashlight/https://ieeexplore.ieee.org/document/9076196http://www.esa.int/Enabling_Support/Space_Engineering_Technology/Laser-powered_rover_to_explore_Moon_s_dark_shadowshttps://www.esa.int/Enabling_Support/Space_Engineering_Technology/Rovers_drive_through_Tenerife_darknesshttps://www.youtube.com/watch?v=eney3cJBtowSupport Universe Today Podcast
