UNIVERSE TODAY

This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe. You'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.

Earlier this year, NASA announced 4 new Discovery-class missions that they were considering. These are low-cost, rapidly-built missions that will help scientists understand some mystery in astronomy and planetary science. One of these missions is called Trident, and it’s going to be targeting the Planet Neptune. And more specifically, it’s going to be providing close up pictures of its largest moon Triton.

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of. That’s why it’s reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone. Thumbnail credit: NASA/Harvard-Smithsonian Center for Astrophysics/D.

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?

Another week, another Open Space. This week I answer questions about what we might see in the next 5 decades. When dark matter will get debunked, and who will carry the Mars torch after Elon Musk passes away. 03:35 What will happen in the next 5 decades? 07:09 Will dark matter be debunked? 10:50 Who will carry the Mars torch after Elon? 13:17 Do I have a PhD? 14:33 Could civilizations be hiding in the infrared? 19:07 What laws should be in place before a mission to Mars? 23:25 If you could name a space program? 24:28 Can light travel faster than light? 25:30 Why aren't we using gliders to access the ISS? 28:12 What if a white hole passed through the Solar System? 29:26 Where do Von Neumann probes get their raw materials? 30:30 Am I happy with the militarization of space? 33:21 Have I read the Bobiverse books? 33:37 What if the speed of light wasn't constant? 35:10 Is Planet X a myth? 37:41 How will James Webb view habitable exoplanets? 39:02 What is the most frustrating space myth? 41:30 Is there something beyond Neptune? 44:35 How do coronographs work? 47:28 Would incoming alien ships unite the Earth? 49:20 Could you fly through Jupiter? 51:48 Should we let aliens know we eat ham and pineapple pizza? 52:25 How can the core of Jupiter be hotter than the surface of the SuN? 53:18 What field does metallic hydrogen generate? 54:00 What sci-fi books would make good movies? 56:40 What's the most likely answer to the Fermi Paradox? 56:53 Is anything in space named after me?

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.

This week we were joined by Chris Elliott, Dave Dickinson, Dave Farina, Linda Thomas-Fowler, and Shahrin Ahmad for our fourth Virtual Star Party. Since we started an hour later, Fraser had good viewing shortly after we went live. In Malaysia, Shah immediately treated everyone to a live, daytime view of Venus. Meanwhile, from Virginia, Linda treated everyone to a view of M101, the Pinwheel Galaxy, for which she had been gathering data for approximately 110 minutes. ******************************************** 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=2 RSS: https://www.universetoday.com/audio What Fraser's Watching Playlist: https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1G Weekly email newsletter: https://www.universetoday.com/newsletter Weekly Space Hangout: https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/ Astronomy Cast: https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSg Support us at: https://www.patreon.com/universetoday More stories at: https://www.universetoday.com/ Twitch: https://twitch.tv/fcain Follow us on Twitter: @universetoday Like us on Facebook: https://www.facebook.com/universetoday Instagram - https://instagram.com/universetoday Team: Fraser Cain - @fcain / [email protected] Karla Thompson - @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fw Chad Weber - [email protected]
