Our galaxy, the Milky Way is the thick stream of stars that cuts across the sky on the darkest clearest nights.

Its spiraling expanse contains at least 100 billion stars, our Sun amoung them.

Each of those stars has not just one planet but like ours, a whole system of them, then the number of planets in the galaxy is truly astronomical.

We're heading into trillions.

We humans have been speculating about such possibilities for thousand of years, but ours is the first generation to know, with certainty that exoplanets are really out there.

In fact, our way out there.

Our bulk of exoplanets found so far are hundred of thousand of light-year away.

The Bad News, as yet we have no way to reach them and we won't be leaving footprints on them anytime soon.

The Good News, we can look on them, take their temparatures, taste their atmospheres and perhaps one day soon.

We able to detect signs of life that might be hidden in pixels of light captured from these dim, distant worlds.
