Will we know it when we see it? In a galaxy that likely holds trillions of planets, ours is so far the only known life-bearing world. We've confirmed only a few thousand of the galaxy's exoplanets, which probably number in the trillions — and already, the variety is stunning. Among the stunning variety of worlds in our solar system, only Earth is known to host life. Can we find another world somewhere among the stars that reminds us of our home planet?

Historic Timeline. A planetary tour through time. The telescope stopped working in Also called KOI It takes days to orbit the star Kepler The study concludes that stars around half the temperature of our Sun cannot sustain Earth-like biospheres because they do not provide enough energy in the correct wavelength range. Pyle shows NASA has decided on October 30, to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2, planet discoveries from outside our solar system, many of which could be promising places for life.

Its flowing lakes and rivers are made of the hydrocarbons, methane and ethane. Flowing water is not an option; Titan is nightmarishly cold, and water is essentially rock on its surface.
If it does, mixing with complex chemistry on the surface could provide fuel for life. We'll be surprised more and more as we continue to extend our senses to the outer solar system and beyond. The planets and moons of our solar system, some seen in this illustration, are extroardinarily diverse. A few show signs of potential habitability. De La Torre. A recently discovered exoplanet orbits two stars and crosses the faces of both; another is in a scorchingly hot, strangely shaped orbit around its star.
NASA scientists create a scale for evaluating possible signs of life beyond Earth. NASA has turned popular posters into cool backgrounds to dress up your digital meeting background or your desktop!
