The list of potential habitable worlds is growing a bit longer, so now we have a few more targets for when we finally master the finer points of warp technology.

Space reports NASA’s Kepler space telescope has found four more rocky alien planets drifting around out in the cosmos — and two of them could potentially support life. The four planets orbit the same star, a red dwarf, and two of them fall in the habitable zone around the star (where liquid water could exist). All four planets are 20-50 percent wider than Earth, and rocky, meaning they could support life. The two promising planets are known as K2-72c and K2-72e.

Though the planets are promising, and could be similar to Earth, they do hold some major differences. The biggest: The planets complete their orbits in 15 and 23 Earth days, and the temperatures are just 10 percent warmer, and 6 percent cooler, than conditions on Earth. We don’t know much about the atmospheres, but the temperatures could be just about perfect to support life.

Though these findings are fascinating, it’s worth noting these planets are about 181 light-years from Earth, located in the Aquarius constellation. So yeah, it’ll be a while until we can get close enough to check them out.

But, hey, #TheMoreYouKnow.
