Astronomers say they are on the point of finding planets like Earth orbiting other stars, which is a key step in determining if we are alone in the universe. A top NASA official and other leading scientists say that within four or five years they should
A planet called Kepler 22b was discovered!It is supposed to be an ideal home for future human. It has both land and water and has temperatures which average around 72degrees. It also has the right atmosphere to support life. But it is 600 light years from the Earth. ...

Kepler, who originally studied to be a priest at the University of Tübingen, wrote: “I had the intention of becoming a theologian … but now I see how God is, by my endeavors, also glorified in astronomy, for ‘the heavens declare the glory of God.’…. Science is the pr...
Planets around quieter or inactive stars could keep water on their surface, which is a key metric of habitability. A planet's chances of supporting life also depend on its atmospheric composition, the scientists found. Earth's ozone layer filters out much of the harmful radiation from our own...

That said, it probably doesn’t. It’s fairly likely that living things from Earth have been blasted into space (by impacts) and have eventually landed on almost every major body in the solar system. Whileit’s possible to survive the trip, living andgrowingon another ...

Kepler’s first law states that planets move in elliptical orbits around the sun. This overturned the ancient dogma that the planets move in perfect circles. His second law describes how a planet travels faster in its orbit when it is closer to the sun. The third law describes how the orb...
