A group of scientists from the University College London discovered water on exoplanet K2-18b. Exoplanets refer to planets outside of our solar system. This one happens to reside 110 light-years from Earth.
“K2-18b, which is eight times the mass of Earth, is now the only planet orbiting a star outside the solar system, or ‘exoplanet,’ known to have both water and temperatures that could support life,” researchers said in a statement.
“Finding water in a potentially habitable world other than Earth is incredibly exciting. K2-18b is not ‘Earth 2.0,’ as it is significantly heavier and has a different atmospheric composition,” said lead author Angelos Tsiaras, Ph.D. of UCL’s Center for Space Exochemistry Data, in the statement. “However, it brings us closer to answering the fundamental question: Is the Earth unique?”
The planet likely doesn’t contain life in a way that we would understand. But, should life develop and become hostile towards Earth, President Trump’s newly-launched Space Force will quickly dispatch those pesky alien invaders.
