When I was a kid, we didn't know for sure whether there were any planets outside the solar system. It seemed likely that there would be planets out there, and one could assert that it was highly probable that they were out there, but we didn't for sure.

Then, suddenly, we did know. Astronomers began to crack the code, identifying the presence of planets by the way stars wobbled and other giveaway behaviors. So then there were a few known planets outside the solar system, and before long there were a few dozen -- to the point where now most people probably couldn't tell you (within 50, or even 100) how many extrasolar planets we have discovered.

Do you know? Take a look.

Surprised?

See we have discovered hundreds them, using various clever indirect detection methods. But no one has ever actually seen an extrasolar planet. Until now, that is:

And then, one the same day we see one, we see two at the same time.

All the details are here. What an amazing time we live in.
