What do u think?

I think her claim needs a lot of peer review.

On "Nature" I found an article about a female astronomer called Claire Max who found a way to calibrate the adaptive optics of big optical telescopes by shooting a laser beam to a layer of sodium atoms in the stratosphere. Her idea was classified by the US Air Force until 1991 and is now used in all big telescopes now under construction in Hawaii and Chile. She is now at the Lick Observatory, where she demonstrated her idea. She is 68 year old. Chapeau.

Hi all, just wondering what your thoughts on Keplar-186f are?

https://www.youtube.com/watch?x-yt-ts=1422579428&v=RlidbLyDnPs&x-yt-cl=85114404

Here are my thought on it...

If this is indeed a habitable planet like earth, It may actualy be earth at a much earlier or later time. If it is a much earlier time, stone age, there will be no way to detect signals from it since radios didn't exist. However if it is at a future time, we should be able to detect signals from it.

EDIT: Post was moved here, didn't see this here earlier.

And still nobody looked at Kepler186 star & see what is the age of the star / planet system? ;)

Kepler 186 is a red dwarf star. It's very difficult to estimate the age of such stars because they change so slowly, over time. One source suggests that the Kepler 186 system -- 'is likely to be more than a few billion years old'.

It looks to me like there has been a great deal of time spent studying this star and it's planets. Afterall we aren't going to be travelling there anytime soon.

This scrutiny might lead, in the not-too-distant future, to the discovery of definite signs of life, even intelligent life. That would be worth knowing, even if we never actually travelled there.

those we can laern now...

for life, presence of CO2 & CH4!
for inteligence, CFC...

we just have to "measure it"...

The detection of oxygen, paired with traces of methane, is now being discussed as one of the best indicators of life on an exo-planet. The amount of oxygen could give some clue about how biologically advanced that life is, as it does on Earth.
Besides radio emissions, we should also soon be able to detect, at stellar distances, light and heat of a sort characteristic of a technical civilization.

as the CH4 & CO2 are in variations throughout the Earth timeline, pic:

so people would really have to consider watching the other pollutants for INTELIGENT species:

prferably N20, NOx, CFC, HCFC & HFCs...
