The very first finding of another planet happened in only 1992(!), which seems a long time ago now, but is really a wink of time.
Before Misters Mayor and Queloz identified a planet, exoplanets were a source of conjecture. The thinking went like this (paraphrasing Carl Sagan):
"Just suppose there are a billion stars out there. Even if only one in 10,000 has planets, then there might be up to 10 million planets. And with a 10 million planets it strains belief to believe ours is the only one with life on it."
Turns out that a shitload more than 1 in 10,000 systems have planets. We have discovered, with the tools delivered by Misters Mayor and Queloz: big planets, little planets, super hot giants, super cold dwarfs and everything in between, including earth-like planets, giant planets with earth like atmospheres and a planet of actual dinosaurs*.
We have, in fact, discovered the universe is a great and fascinating place we may be able to explore one day, if we don't blow ourselves up.
