We are not alone.

 Hello? Anybody out there? Are we alone in the universe? Or is there life somewhere in space or “in a galaxy far, far away?”

Earthlings have been obsessed with such questions since God knows how long. Isn’t that why we just so love science fiction? We enjoy fantasizing about the possibilities of life beyond our own planet, perhaps just for the comfort of dreaming that we are not alone in this big, wide universe.

Within our solar system, no other planet has been confirmed to support and sustain life aside from earth. But what if we looked beyond? Could life exist outside our solar system? 

For years, astronomers have been searching for exoplanets or planets situated outside our solar system. Out of more than 3,000 exoplanets confirmed since the 90s, the most interesting are those that share some similarities with earth and those that are potentially habitable. But most of them are extremely far from earth to examine for signs of life. Humans simply don’t have the kind of technology capable of looking for life forms in areas that are far too distant from our planet.
