The Mysterious World of Kepler-452 b. In Search of Extraterrestrial Life

The universe … is filled with countless other worlds. Among the thousands of exoplanets discovered beyond the Solar System, none can yet be considered more hospitable to us than Earth. With some melted by the unbearable heat of nearby stars, others are forever encased in ice or scorched by devastating radiation. But among the many inhospitable worlds there are others that are quite different. There are great waters of oceans and rivers on their surface, clouds float across their sky, and showers and thunderstorms rage in their atmosphere. Perhaps these worlds can become the cradle for beautiful and unique life, as has once happened on the Earth. And today we're going to visit some of the most remarkable of them.

Hello, everyone! We are back! There are quite a few new great videos coming right up!

Finally an upload after 238 million years 😆

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...

[mehhhhhhhhhhh]

imagine if other beings on those planets are watching the same thing about earth in a youtube-like app 🧐

[dentoncrimescene]

Wow, i wish i could be alive long enough to see some of these.

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)

We need more technology to get there maybe in the next few centuries 😊

So basically, an exoplanet needs to be just like earth, exhibiting the"Goldilocks effect"..I'm sure there's one out there somewhere.

[jonasezekiel]

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.

[hugocardona]

Like they say: Good things come to those who wait... thanks Kosmo....

[antitheist]

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. 🤩🙂

[stoerenungeheuer]

Could you bring back spoken "Kosmo" at 1:04 ?
Would be great!
In any case: Welcome back!

[ItsDraxxx]

Brother need a video on andromeda galaxy as much knowledge u can give about the galaxy not about the collision❤❤❤❤❤

[gauravsinha]

These documentaries seem to be far more informative, well narrated and better than those of Discovery Science's, History Channel's and Nat Geo's.

[irishexerset]

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.

i should be searching for a job, but what am i doing here🙈

[Titus-as-the-Roman]

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

[LT.dans_new_legs]

Isn't this Halo's planet Reach?

[sumanthbudugu]

All fun and games until we all get a text saying “you are bugs” 😂

[johnbrimmer]

Have you been reading my mind? Thanks for another fantastic upload!!!
