New potentially habitable plantets found

This is big, NASA's Kepler discovered three 'new Earths' in the habitable zones of the two new planetary systems.

NASA's Kepler spacecraft is doing a great job finding new planetary systems and earth like planets orbiting another stars, and its latest discovery is no exception. The Kepler mission has discovered two new planetary systems containing three 'Earth like' planets that are orbiting in the so called habitable zone, meaning they at the exactly right distance from the star to be able to contain the liquid water. The systems have been named Kepler-62 and Kepler-69.

On the image above, you can see all the planets that have been found in the habitable zones so far by Kepler compared to the Earth (far right). From left to right they are called Kepler-22b, Kepler-69c, Kepler-62e, Kepler-62f. The last three are the newly found planets. The Kepler-62f is only 40% larger than Earth, making it the closest in size yet to our home planet.

On the NASA's image above you can see the Kepler-69 planetary system with its habitable zone, where water on a planet's surface could theoretically exist in a liquid state. Scientists believe, that liquid water is crucial for life such as humans to develop.

And the Kepler-62 planetary system with it's two potentially habitable Earth like planets, Kepler-62e and Kepler-62f. The Kepler mission continues and we are looking forward to learn about its new discoveries and hopefully in a near or distant future, we will find the answer to the ever so mind-boggling question, "Are we alone?"
