Title: Will astronomers will be able to image Earth-like planets by 2025?

Hi,

I would like to share with you guys a couple of interesting simulations.

This simulation belongs to an Earth-like planet located 4 light-years away, imaged with the European Extremely Large Telescope (ELT), expected in 2025:

This other simulation belongs to an Earth-like planet located 40 light-years away, imaged with the Large Ultraviolet Optical Infrared Surveyor (LUVOIR), expected in 2035:

What is the first exoplanet you would like to see an image of?

I would certainly like to see more compelling and direct evidence on exoplanets...current methodology involves finding a star with a predictable, periodic dimming...then using standard orbital dynamics to postulate what size planet in what orbit might account for the dimming, in sort of a mini-eclipse. (Some also postulate the composition of the planet and presence of an atmosphere on these newly "discovered" exoplanets.)
I'm skeptical about the interpretation of the data...the researchers are specifically looking for exoplanets. When all you have is a hammer, everything looks like a nail.

Not always. Didn't you see that link I posted when you brought this up before?
