Can NASA estimate the age of kepler-22b? or how old the star of this planet

[From: ] [author: ] [Date: 11-12-17] [Hit: ]
BUT NO ONE CAN SEE KEPLER-22B.And no one can determine the age of the star.We CAN determine its life time based on size, but we DO NOT know when it was first born.Your assumption that evolution uses a fixed time frame is incorrect.There is NO scientific reason to believe that life evolves on all planets at the same rate.......

Cheers!

How bright a star is is a function of mass as well as age.

It could be less massive than the Sun.

ESTIMATE its age?!?!?!? They can't even SEE IT!

Kepler was found using the "occlusion" process. They focused their telescopes at the star, and HOPED that a planet would pass between the star and the telescope, causing a kind of "mini-eclipse", making the star dim slightly each time the planet passed. Three such "occlusions" indicates an orbit planet.

They ALSO measured the stars "wobble" that is caused by an orbiting planet. Using these two pieces of information, they KNOW that a planet IS there, and its approximate size, and its approximate orbit. Given the size of the star and the approximate orbit, they know that the planet is about the right distance from its star that it MIGHT contain liquid water. No guarantees -- just guesses.

BUT NO ONE CAN SEE KEPLER-22B. And no one can determine the age of the star. We CAN determine its life time based on size, but we DO NOT know when it was first "born".

Your assumption that evolution uses a fixed time frame is incorrect. There is NO scientific reason to believe that life evolves on all planets at the same rate. We COULD NOT estimate the phase of evolution even if we knew the exact second the star was born.

The OTHER assumption is that there IS evolution on that planet. Again, there is NO scientific reason to think that there MUST be evolution on that planet. It might very well be warm and watery -- and totally barren. Maybe Evolution hasn't happened yet -- or maybe it never will. There is even the possibility that there is no such thing as evolution, and that the Bible IS the right answer.

And we will NEVER know, as Kepler-22B is WAY too far away to be properly measured, and cannot be seen even with our most powerful telescopes.

Not really. Kepler 22 is slightly less massive than the Sun,. It's spectral type is G5. All scientists can do is ESTIMATE the age of both the star AND any planets. There is NO PHYSICAL RAW data, like actual rocks with radio active isotopes, for radiometric dating techniques and analysis. Astronomy is the premiere remote sensing science. No matter how many smart-*** questions people ask, all real scientists can do is ESTIMATE, as long as there is no PHYSICAL evidence, like a meteorite, to analyze.
