lmao reminds me of the time we thought venus was habitable. we were right in thinking it was hot. but we were so wrong about what kind of heat. We expected the tropics, not hell haha.
Didn’t mention that it is most likely a tidally locked, eyeball planet. This would mean weak magnetic field and one side of the planet always facing the star. If life was here it would need to be able to survive in much harsher conditions then Earth.
Yes...though I suppose there might be a "terminator line" the area of permanent twilight where conditions are just right. Assuming sunny side is too hot (maybe it isn't) and night side too cold/dark (likely). The other issue is how long has Teegarden "B"'s host star been "quiet". Our window of observation is two brief to know its long term history.
I was waiting for the video to mention of tidal lock and as stated already there would be a transition zone. My guess is that with Libration and TB being slightly larger than earth the transition zone would be approx 60 miles (give or take). Thats a pretty sizable area and if you were on planet in the transition zone the sun (Teegarden) would rise over the horizon to some point in the sky then stop and set in same place. ie A sunrise and sunset in the 'east''.
Yeah but if it's tidally locked it won't have a magnetic field to protect its surface from radiation which would be intense from even a relatively quiet m dwarf.
@@Fresh_Productions 7 day orbit around the dwarf with tidal lock may produce tides of upto a mile high, if not oscillating tsunamis. Trying to imagine the impact of moon to earth vs dwarf sun to similarly sized planet. Strength of the gravitational force is unknown I think.
Teegarden b if it has life at all, most likely has highly evolved life. Teegarden Star is a Red Dwarf with a lifespan measured in the trillions of years. Teegarden b's life could have had hundreds of billions of years to evolve while it endlessly orbits its star. This is why Red Dwarf systems are thought to be some of the best places to look for intelligent life.
I think there were more oxygen levels back in the early earth periods. Everything back then lived longer and grew much bigger because oxygen at that time was more dense, and rich than it is today. Dinosaurs had nostrils like horses. Size comparable. In order for something that large, it would need a tremendous amount of oxygen. One lung full of oxygen then, would be the equivalent of two and a half lungs full today
The average temperature on this planet is 28 degrees Celsius, which is a very good indicator, but most likely there is a range of temperatures, in one place it is too cold, and in another too hot. And the planet is most likely not protected from radiation, the presence of an atmosphere has not been confirmed. Poor conditions even for the simplest life forms
ahmed hosny I’m guessing you don’t have an education in biology? Evolution is one of the most tested scientific theories in existence. It has withstood almost 200 years of scrutiny.
Wow, it seems like you know everything. I would simply say this, if we go there we can’t bring any liberals and absolutely no Socialist. So Bernie the clown hast to stay here.
When James Webb launches in 2021 it will probably look at the composition of the atmosphere and the material so we will probably know if it has life or not.
The human ego is insanely huge lol. Why would we be the only planet containing life out of billions of planets? Even on a smaller scale, no one is "special". There's probably an entire galaxy full of planets containing unknown species that have a much higher intelligence than our own kind. We just haven't made contact yet.
Since Teegarden is a Red Dwarf star would Teegarden b not be Tidally Lock with on side of the planet facing the sun. Which would mean one side would be bombarded with Radiation from the Star and the one side facing the star would be way to hot for life and the dark side would be way to cold for life.
There will be a strip of habitable area in the terminator between the hot and cold side where life can evolve and we know that once life does appear, it can even survive literal hell.
Aires Constellation, 12.5 light years from Sol (Our Sun), Red Dwarf star that doesn't flare up, lies besides near constellation Taurus and Orion. Red Dwarf Star cannot be seen with the naked eye other than large telescopes, and only has 2 planets in the system. If this planet is indeed habitable and suitable for life, then we shall go there rather than our closest neighbor Proxima B in which is a flare red dwarf star.
The earth like planets with small red dwarfs are probably are not the best candidates in my opinion. They are probably tidally locked which means only a section of the planet is really habitable. It likely has some life but possibly only simple life. I think the best are earth like planets with a sun closer to our own.
Proxima B Vs Trappist 1e vs Teegarden B ? Who will win in context of estaiblishing new Human colonies and supporting life , considering distance for each planet, World !!!
45,000 light years away planet maybe have smart life on it bcs we can observe it's past only, i mean if it is 45,000 light years away it means that we can only observe 45,000 years in past.
@0 0 but 12 light years would take thousands of years to get to endless we could travel at the speed of light. I just don't understand how we know about planet's so far away
The closest star system is around 3.5 LY's away and it would take us 70,000 years to get there, and it does not appear to harbor life! You do the math!
12.5 light years is about 105 trillion kilometers away. Even in 10 or 15 years time we won't be able to go even remotely close to there. Better off to colonize the Moon and Mars, much easier.
Have we built a space probe for deep space that looks for Advanced extraterrestrial life yet that would receive radio transmissions or communication transmissions of alien life forms
Believe is a word one uses when there is no knowledge and we need a placeholder until - so completely not correct here, we know we came from single-cell organisms via evolution.
I would say if it's dwarf star it would be an old system, and the planet would be old. I think we'd find ruin's if we'd ever explore this planet. From what I know it looks like this planet is in a title lock with the star, so the temp's would be very hot on one side and very cold on the dark side. This would mean that there maybe a strip of surface where the climate it warm. Atmosphere's such as this would cause some violent storms.
Look at the problems we'e having with the Coronavirus. Imagine virus that evolved somewhere else. Talk about illnesses we've never seen before. Think about fungus that can eat glass and it's attached itself beween your toes.
Whose Idea was it to narrate this as if you are addressing a 5 year old boy....really misguided...I can assure you that any 5 year old boy interested in this issue would resent being talked down to !!!!!!!!!!!!!!!!!
