TRAPPIST-1 Updates: With First 3 Planets (Out of 7) Finally Analyzed

Thanks Anton for your dedication to this channel. it’s one of my all time favorites

Earth being called "a very special little place." Anton is good at science and at a touch of whimsy. Thank you for sharing all the wonderful things with us.

We only bother to look for life around red dwarves because there’s so many of them. Problems include super flares, lower material for planet formation, life limited to one hemisphere, tropics being a point instead of the equator, no seasons, slower winds, high tidal stress, more vulnerable to ice ages, CO2 precipitation in the far side, 90% of water becoming glaciers, infrared being inefficient for vision and photosynthesis (particularly bad for methane/ethane planets), and possibly more stable star systems that prevent the clearing of their Kuiper belts.

Trappist-1's planets are in resonance. They formed where they are, with little migration. Other worlds in other systems formed further away and migrated inward. Migrate worlds retain "ices" (like water) from outside. So do comets and maybe Theia-likes. So I find unlikely that Trappist-1's inner worlds, up to -d, have water.

On some other planet, astronomers are exited about planet Neptune - it’s in the habitable zone, where liquid methane can exist.

Love ya Anton! 😊❤

Thank you for another great video!

Something may not seem possible right now, but I remember a time when they said, "We'll never be able to detect exoplanets". We can see a bit further than Galileo. Certainly some wonderful future person will be able to see farther than us.

9:52 My brain is primed to expect that head spider creature when that plant shows up, but it still startles me every time.

i love the fact he admits we dont lnow things just have theories based onour own neighborhood like having an oopinoin on what kansaas is like based solely on two weeks in newyork.
