One thing you forgot is that higher gravity means higher air pressure at the surface level. So if the exoplanet has 2 times the gravity of the earth and still has a thick atmosphere, the result is that we will probably not be able to breathe normally like we do here on earth, even if the chemical composition is the same. The increased pressure can impact gas exchange in the lungs and the solubility of gases in the blood and tissues. Not to mention how hard it will be to inhale...
A recent update in regards to M Dwarf flares. "A 2021 study lead by Ekaterina Ilin (Leibniz Institute for Astrophysics Potsdam, Germany) presented evidence that M dwarf flares tend to emanate from their polar regions, possibly sparing close in planets from direct hits. Their initial data was taken from a small sampling of M dwarf stars from TESS observations, and further studies showed that this may well be the norm." (from Universe Today 8/7/21)
There are alot of them in our galaxy but the problem is getting there. With some time intervals as much as 186k years to get there lol and that's at the speed of light
It would also need to have been formed in just such a way as to have a molten iron core spinning in just such a way as to produce a magnetic shield to protect the planet from radiation. The universe is positively sizzling with deadly radiation. It could be 72 degrees and sunny with oxygen and liquid water on every one of these exoplanets but they are likely all barren irradiated wastelands. Earth won a trillion to one lottery in having so many factors line up perfectly for life, and then intelligent life, to form. Either that or it was designed so. Whatever you believe, such a series of conditions must be so rare as to be very nearly impossible. Thus the great silence.
@@warriorplutotrent3827If one travelled at speed of light or close would they not travel almost instantly from their point of view so its not 186k years for them but for us at Earth.
@@alper8974 is not instant. I thought it was too. But to travel to a galaxy like Andromeda at the speed of light will still take several hundred thousands of years to get there
Outstanding, very interesting topic. The idea that we could eventually get to these places fills me with a child like excitement, TY for making my day. 🤩🙂
I waited 20 mins for a KFC only to be told they had no Hot Wings left and understaffed and told it was my fault for ordering something that always runs out.
I've a feeling we may find bacterial life but advanced life is going to be isolated on Earth. EVERYTHING about the Earth is perfect for life, Earth being in the Galaxy's Goldilocks zone, you might think you would find more planetary systems like Sol's, the Fact that we don't is a Bad Omen
I know that most of these videos are specifically speaking on exoplanets. But it is still important to remember that it is entirely possible that we will find life in multiple places outside of Earth, in this system, before we find potential life on an exoplanet. Bothars and Venus being the closest contenders to us, to have rare or otherwise distinct forms of life, and several moons and Pluto being the most likely places to find complex or semi-complex life that we know of so far.
No life anywhere yet except on the earth. It's very lively here. Protests going on, wars, voting. Scientists are babes who love to dream and use other people to fund their dreaming. I saw one hugging his comfort pillow while explaining the universe. How practical is it ? No wonder the earth is crumbling away as the eyes are up looking in vain for life?
I think it might be wise to consider another factor, the existence or lack of a Jupiter mass body in the outer solar system of a target exo planet. So as to attract and absorb significant comets and asteroid impacts, thus protecting the exo planet for periods of time long enough for life to develop.
Tidal locking alone is not a major issue, in fact in may guarantee a habitable zone on a planet near the transition area. One side too hot the other too cold but between the two will always be a just right medium zone, may lend to a reduced population or limited area. Powerful currents would be likely as gases and liquids attempt to equalize.
Is it just me that notice every planet that’s in the habitable zones are always locked . Our solar system is rare and very beautiful .every moon every planet in our solar system helped in our creation
Kepler-43 b is a gas giant exoplanet (made almost entirely of gas) that orbits an F-type star. Its mass is 3.23 Jupiters, it takes 3 days to complete one orbit of its star, and is 0.046 AU from its star. Its discovery was announced in 2011.
I'm here to thank you and everyone who puts so much work into making such amazing content, your channel believe it or not has helped me through difficult times, i will forever be grateful ❤ thank you kosmo
We are here for a reason not by accident, no hospitable planet we will ever find in the universe. Every planet we are trying to colonize will always depend on earth for resources which means more difficult and costly to sustain life so why not fix earth.
Not only is the universe full of life, there's a whole range of species from different timescale evolutionary periods, from primitive cave beings to the super advanced beings we see in our skies. On that universal timescale we're probably down in the primitive side, just out of the caves in universal timescale.
Sorry to replyguy twice here, but GJ 1002's planets are not transits. So their masses are minima, not estimates; although the Hill Spheres do seem to point to not being much more massive than detected. More seriously we have no idea on their volumes; although, I tend to agree that they'll probably scale close to their masses. That is: that they're rocky, especially the inner one, and not very icy (because of the radiation my other posted noted).
But couldn't life be totally different with different needs than us? ... I mean, maybe they don't need all we need, so maybe their plants are nothing like Earth, so maybe we need to keep our minds a little more open .
He has hundreds of them the number shows the location in the list of those. The name reflects which survey found it. Wolf, Kepler and others all have hundreds in the catalog.
The universe is full of life but we shall never ever hear from each other, why we destroy ourselves as soon as our technology is advanced enough to communicate, look at earth in only 100 years we went from horses to nuclear weapons and we're heading for m.a.d, most civilization probably last 10,000 so keep looking 😅😅
So Kepler-452B potentially can have a life, right what if whoever lives there created a dom like structure favoring the best conditions? and they live only on certain parts of the Planet? We will never know it
Being 0.046 AU from the red dwarf and assuming the stellar wind at the surface goes out at the same density as the wind from the Sun, the 1002b planet would be blasted by stellar wind 470 times stronger than the Earth due to the inverse square effect. Flares on the star would also be greatly amplified by the same 470x factor.
It's not a flare star (GJ 12 isn't either) but your other critiques are valid. I've made a side comment on further reasons to discredit this planet, just published a few weeks ago.
Really enjoyable video, except for the grammar nerd inside me that gets riled up hearing things expressed as "four times less massive". Please please PLEASE correct to "a fourth the size" in future projects.
Even if a perfectly habitable planet is found not nearby but far away, how realistic for humans to inhabit it? BTW, i missed the deep K O S M O announcer 😢
Guys i think the world is round not flat.because inorder and adject to spins its have to be round.if the world is flat it cannot spins round and round only flip over and over.so its have to be round to spin.so that why i think the world is round guys..😅😅😅😅😅😅
