Scientists Think Life on Proxima Centauri B Would Be Unlike Anything We Have Ever Seen!

The closest exoplanet to us, Proxima Centauri B has captivated the imaginations of scientists for years. Why? Because it is about the same size as the Earth and it orbits its star within the habitable zone, meaning it could be a world capable of supporting life, and it's right next door! So could this mysterious exoplanet really host alien life? Some scientists think so and they have simulated how.

Proxima B has spent the last few billion years being blasted by megaflares, it's almost certainly an airless, dessicated rock.

Proxima b is more dead than Mars. It would have tidally locked to its star long ago and it has no way to maintain a magnetic field beyond sharing one from its host star. Simulations show that life could perhaps thrive on _young_ worlds around red dwarf stars. Proxima b is _old._ If life still lives there, it must be more extreme extremophiles than any we've seen on Earth.

Venus is in the Sun's habitable zone, has water vapor detected in its atmosphere, has a rocky surface, and is almost the same mass as Earth.

[meysamghahremaninejad]

Tidally locked, Irradiated, no atmosphere, barren, dark and bleak, hot and cold, lifeless and hostile. that's just how Proxima b is expected to be!

[Casperthegator]

I really hope there is life somewhere in the universe and if it's close to our home, that will be an amazing discovery for all of humanity. Knowing we are not alone in the vast cosmos.

Statler: You suppose they have any life on other planets?

Waldorf: What do you care? You don't have any life on this one! Hohoho!

it sucks that despite red dwarfs making up at least 3 quarters of all stars (in the milky way anyway) and have a life span longer than all other types of stars combined, scientists see just as little likelihood for life around the common and long living red dwarf stars as the very rare and quickly dying blue stars. let's hope that if we ever get the potential to discover new life, we can also discover that it is indeed possible for red dwarf stars to have planets teeming with life despite the extreme hostile conditions of the star

Apologies for any harsh criticism, but I was rather disappointed.

As a huge fan of speculative evolution, from the title I assumed this would be describing what alien life on Proxima Centauri B would be like, at least in *some* level, but instead it was only a description of about the planet itself and what the environment may or may not be like, with little to no information or speculation on how it might shape and influence the development and evolution of life on its surface.

Imagine us as a species attempting to get along with other beings when we have not yet figured out how to do it on our own planet/ country/ town/ village/ household.

11:30. The JSW can't detect anything about proxima b, because the planet does not transit relative to our view.

That means the planet orbits in a plane, that makes it hidden from direct observations on earth.

The only way to know what proxima b looks like will be through drone/ probe imagery

[ellisonhamilton]

Speaking of Star Trek we need a Federation star ship to visit places like Proxima B. It's wonderful that we live in a time when we are learning so much about the universe. It is also frustrating that we can't reach any of the places we discover. The distances are just too vast. And it will undoubtedly take centuries before we can even send robotic missions to these places.
Great video. Thank you. You and Rolo have a great weekend. 🇺🇸❤🇬🇧

[paulcateiii]

thanks Rob - always look forward to your videos

We are not capable of imagining life beyond earth, whatever our imagination is, it still adheres to the life we see around us imagining eyes, facial features, arms, wings, legs, tantecles etc. These are all what surrounds us on earth.

[GadreelAdvocat]

It's a good possibility. As various stars that have passed by our Sun. The interactions between the meetings of other stars over several billions years might have sent some organics to our closest neighbor star. Proxima passes in the Centauri systems "Oort" cloud. It would pick up icy materials over and over again. Even if it's atmosphere is stripped away from solar flares it might gain it again as it travels in such an orbit.

[aldonco]

It is extremely foolish to think we are the only life out there with billions of other galaxies out there.

[TimDoyle-le]

There was an Outer Limits episode about an expidition to a tidally locked planet called "The Mutant"... They landed on the daylight side and it rained radioactive particles... 😬

[AhmedYT]

back at it again with another great video keep up the marvelous job {ROB}

[AuthorWASimpson]

Writer research questions: If Proxima had a yellow sun like ours could it be habitable even though tidally locked? Any theories on what type of lifeforms would occur there on either the light and dark facing?

[TravisCotter]

After a few seconds of debate I am ready to take the trip to ProXima Centauri. Mr. X
