Do advances in technology mean we're closer to finding alien life?
The hunt for ET really is hotting up. Just a few decades ago, the idea of alien life was primarily the realm of fiction. In reality, it seemed the universe was a cold, dead place bereft of life, save for what clings to the surface of planet Earth.

Cosmologists were amazed by the discoveries, but not too surprised. After all, the notion of planets orbiting stars other than the sun was speculated upon by the Italian philosopher Giordano Bruno in the sixteenth century.
