When do you guys reckon extraterrestrial life is discovered and in what?

I think it's pretty likely that signs of life will be detected in exoplanet atmospheres in the 2030s or late 2020s. These will be confirmed for sure in the 2040s or so. Techno-signatures, such as radio signals, are also theoretically possible in this time, but I think it's pretty unlikely.

Direct evidence and contact with extraterrestrial life will take way longer, depending on if other bodies in the solar system harbor life. If they do not, direct contact might be a reality in the 22nd century or it might never happen altogether.

Pic related is probably not possible until kilometre sized space telescopes, which can never happen.

Is it theoretically possible to take this accurate photos of exoplanets? What kind of a telescope would we need?

When would you estimate that humanity will find first signs of extraterrestrial life?

Nasa just stated that biosignatures (signs of extraterrestrial life) are likely to be found within two decades.

Do you think this is feasible/possible? Biosignatures would only reveal that there IS life, nothing specific.

thoughts on these? NASA recently said that it is very likely to find bio signatures or direct evidence of extraterrestrial life in the near future, 10 to 20 years.
