We know water is cool. That is one of our core beliefs. Recent news says water may be intergalactic and that has us, well, over the moon.

Researchers at the University College London delivered out of this world news when they interpreted recent data from the Hubble Space Telescope. Water vapor was detected on a planet believed to be eight times the size of Earth. Scientists believe the planet, known as K2-18b, is the only planet orbiting a star outside the solar system with water and temperatures that could support human life.

But hold up before you book yourself on NASA’s next shuttle. Scientists don't think the planet, which is extremely far from earth, can sustain human life. K2-18b is exposed to a lot of radiation from its star, making it inhabitable for humans.

For now, we'll sleep tight with the knowledge that water exists on at least one other planet, far, far away.
