Always the question for this stargazer, and I am a stargazer, is why people have a desire to speculate there is life out there? And, for what purpose is there in "affirming" what cannot be proven? In the above if they start today it will take 80 years minimum to find out. Convenient speculation, eh?
I suppose if I have a complaint it's how silly the movies are about the subject these days. Hollywood needs do better.
I do understand the desire of the astronomers though, the telescopes are amazing. One I saw in a GlobeTrekker show in a remote part of Argentina must be the holy grail of astro-scientists.
I do love the Hubble images like what you linked to, but the artist's graphic above is misleading, even silly. It reveals the real purpose of the speculation, funding. Inasmuch as it is Belgians, or Argentinians, or SETI, or other privately funded, wonderful! But if it diverts from useful scientific research, not so useful. NASA has many other useful pursuits better for the time & money.
