PASADENA (CBS)— NASA announced a major milestone in the quest for life in the universe Monday: The discovery of another planet close enough to Earth that it could support life.

The planet, dubbed Kepler-22b, has a radius 2.4 times that of Earth and is 600 light years away, according to NASA. It’s the first planet confirmed to be in a “habitable zone,” a region around a star where liquid water can exist.

In the case of Kepler-22b, its star is similar to the sun, though it is slightly smaller and cooler. It takes the planet 290 days to orbit the star, according to NASA.

“This is a major milestone on the road to finding Earth’s twin,” said Kepler program scientist Douglas Hudgins.

Astronomers don’t yet know if Kepler-22b is predominantly a rocky planet, such as Earth, or made up mostly of gases or liquids.

Kepler-22b is the first planet confirmed to be in a habitable zone found by Kepler so far.

    Hmmm….. yet MORE scientific facts that support the truth within LDS gospel doctrine. I’m not surprised by these findings in the least bit.

    So when we develop a probe that can travel the speed of light, it will only take 600 years to reach it. When will achieve warp drive for space travel?

    That Planet is off limits!

    Think we need to fix this planet first!
