First Ever Image of a Multi-Planet System Around a Sun-Like Star Captured by ESO
This is nice work. I am amazed at the advances in planet discovery from "other stars 'might' have planets" to post Kepler "more than half the stars have planets."The other "unknown" is under what conditions can intelligent life evolve? Once you know that window, the Drake equation gets even more interesting.The notion that we are the only intelligent species in the galaxy seems more and more unlikely.
