    When it is found: Planet Nine Until it is found: Planet Nein

    it must take so much time and effort to put all these videos together time and time again. I hope Fraser realizes how much we appreciate them.
  • @cosmisweb
    Fraser, I wanted to thank you for answering my questions. I have been watching your channel religiously and it’s been helping me cope with my personal struggles. Your love and enthusiasm for astronomy is uplifting. You make complex theories and concepts easy to comprehend, though sometimes I have a hard time understanding some of the discussion in the interviews. Nonetheless, I continue to watch every single one in hopes of gaining more understanding and knowledge.

    Vulcan: Couldn't planet 9 be visible only from the northern part of Earth (at least for now), and if so, doesn't that mean that the Vera Rubin telescope won't se it?
  • @DanielVerberne
    30:10 - Regarding the whole 'life is resilient' notion, yes, life on Earth is remarkably tough. However, we still know very little about conditions that might be required for Abiogenesis itself. Once life is 'booted up', so to speak, it may well have some sort of common 'toughness', but that's once it has somehow crossed the invisible boundary between geochemistry into biochemistry.
  • @zapfanzapfan
    Persephone, queen of the underworld, would be my choice for naming Planet 9.
  • @voodoochile7581
    Fraser, you are so good at what you do. Your channel is amazing. I learn so much from you. Keep up the good work.
  • @revmsj
    Here’s to the algorithm!πŸ‘πŸΎ Also, I appreciate your answering my question! It was actually a case of serendipity because I had asked that question rhetorically to another person in the chat who had asked something about bio signatures. I nevertheless got to converse about a favorite topic of mine via the Q&A show, and that equals a win in my book! Thank you, sirs and ma’am’s!
  • @Alekosssvr
    Hey, Fraser, this was an excellent Q&A session. Bravo!
  • Question: Due to interstellar clouds we can't see the center of our galaxy (with our naked eye). What would the night sky look like if nothing obscured our view? Would it be a massive difference or just some extra bits added to the Milkyway that we can already see?
  • @JarrodBaniqued
    My choices would be Antevorta, goddess of the future, Providentia, goddess of forethought, Scotus, god of darkness and shadow, and Terminus, god of borders.
  • @MrVontar
    Thanks for the videos Fraser! You could always dial back on videos to the point where you feel better about the content or time obligations. It can really be hard if you work for a long time with no results but the nice thing with youtube is they accrue over time. Just an idea, got a new sub from me!
  • I have two suggestions: 1. Persephone. Makes sense if you think about it. 2. Nibiru. It'll drive the Sitchin fans batshit! πŸ˜‚
  • Simple: restore Pluto to Planetary Status, then "Planet 9" becomes "Planet X". TA! DA!
  • @brucethomas471
    I sure laughed when you were discussing technosignatures in exoplanet atmospheres, saying that we could tell where they are in their civilization, like destroying their ozone! Dark humor!!πŸ˜†πŸ’₯
  • @sh4mst0ne
    I think Planet 9 should be called Erebus after the Greek God of Darkness.
  • We need to collectively nominate Fraser and his team for journalism awards. How do we get in sync to do that. With his permission of course. We could communicate through discord or patreon or something. Im not good at this but someone surley is good with organization .etc. Fraser you deserve it 1000%
  • @zimmy1958
    Love the show never miss it. Thanks

    Hey Frasier! πŸ‘‹ For Planet 9 -- "Eureka" 😁 Mike in San Diego. πŸŒžπŸŽΈπŸš€πŸ––
