Is there extraterrestrial life on Proxima b ?


Posted on Saturday, 8 October, 2016 | Comment icon 15 comments

Could there be a habitable planet in orbit around Proxima Centauri ? Image Credit: NASA
Scientists believe that a nearby extrasolar planet is 'likely' to be capable of supporting alien life.
Situated only 4.2 light-years away in orbit around the red dwarf star Proxima Centauri, this small terrestrial world, which was first discovered back in August, could be a genuine Earth 2.0.

Now according to a new study by a team at the Marseille Astrophysics Laboratory (CNRS), there is a particularly good chance that Proxima b could offer conditions that are favorable to life.

"This planet, called Proxima b, is in an orbit that would allow it to have liquid water on its surface, thus raising the question of its habitability," the team wrote.

"It is likely to harbor liquid water at its surface and therefore to harbor life forms."

The planet will undoubtedly represent a tantalizing target for future interstellar space missions.

"The fact there could still be life on the planet today, not only during its formation, is huge," said study leader Bastien Brugger.

"The interesting thing about Proxima b is it is the closest exoplanet to Earth. It is really exciting to have the possibility that there is life just at the gates of our solar system."

Is that 20 years that would elapse here on earth, or 20 years in space craft time.... which would mean longer time here on earth ?

And hopefully smart enough to ignore us.

They are referring to earth time. 20 years here.

What is Earth Time?

Actually at 20% the speed of light time dilation effects are negligible so there is no need to differentiate between ship time and Earth time.

Then we also need to add on 4.5 years from when the ship lands ... till when we hear about it. And another 4.5 years for our instructions to get back to it.

Asking a robotic lander to turn its camera would take 9 years to see the result, lol

Wouldn't wafer thin robotic video cam burn upon entering the atmosphere ? And ironically the closest habitable planet is located in a solar system nearest to our star.

The difference would be about two percent. That sounds negligible, but over twenty years it is five months. That doesn't sound so negligible.

I would guess the probe will have a pre-programmed routine to do and we won't have to overview any and every move she do. We could send her more routine patterns when we will have more details.
