planets with life

But its icy moons – especially Europa – have potential. The universe is so young that light from this distant  region of space hasn’t had time to reach us yet, and because the universe is expanding at faster than the speed of light, we will never be able to see (or reach) this portion of the universe. 1) Kepler 186f Kepler 186f Via NASA/JPL-Caltech/T. Sadly, the world is  490 light-years away, so it would take us hundreds of thousands of years to reach (even using very liberal and generous estimates). Because this is a triple star system, these are two of the strangest potentially habitable worlds that we’ve ever discovered. The alien world, which lies 490 light-years from Earth, is just 10 percent bigger than our own planet and is almost certainly rocky. Gliese 581d is another one of our galactic neighbors (in the grand scheme of things, it is basically just around the corner). Generally speaking, in order to be considered a candidate for Earth-like life, the planet must be in the habitable zone of its star, terrestrial (i.e., not a gas giant), and within the acceptable size for life to form (generally, 0.5-2 times the mass of the Earth). At least one study supposes that Gliese 581d might have a thick, carbon dioxide atmosphere. To give an answer to this question, below are discussed about top 10 proof of alien life on other planets. Here's a list of 10 of the planets we know of that are most likely to host alien life, according to the University of Puerto Rico at Arecibo. The next value fc is the percentage of these intelligent life planets having the capability of interstellar communication. They have three suns. A planet with a water cycle, habitable atmosphere or volcanic activity can replenish and circulate nutrients [source: Lunar Planetary Institute]. It lies about 42 light-years away from Earth in the constellation Pictor. But again, due to the decreased size in the star, it is still well within the bounds of Kepler 283’s habitable zone. A planet that occupies such a "Goldilocks spot" that is "just right" must also be free of the bombardment of excessive amounts of very high energy radiation (i.e., x-rays and gamma-rays).Those would seriously hinder the development of even basic life forms such as microbes.

Pyle. While Kepler-22b is bigger than Earth, it circles a star that is quite close in size and temperature to Earth's sun. It orbits its parent star, Gliese 581, about every 30 days in the constellation Libra. This falls well into the category of  potentially Earth-like planets, as it is within the habitable zone of its star, is terrestrial, and is just 10% larger than Earth. However, scientists also believe it could be rocky with liquid water. ... 10 new planets that could have life. One of the most likely candidates for life as we know it is Kepler 186f. The planet is at least 4.5 times bigger than Earth, and takes 28 days to make an orbit around its parent star. And the kicker? But that might not be the case - as astronomers have pinpointed two dozen “superhabitable” planets which might actually be better than Earth. The planet is seven times the mass of Earth, which could make it a very large rocky planet or a dwarf gas giant. You will receive a verification email shortly. Kepler-186f is the first truly Earth-size exoplanet ever found in its host star's habitable zone. Even if the planets do not have life now, it could evolve. Ultimately, Kepler 186f is just the outermost of the 5 known planets in the Kepler-186 system. exploration on surface and atmosphere of planets as the visual observation of the relations between the molecules of life.

Visit our corporate site. Behold this actual in-game footage. Although life on Earth is believed to have developed from a hot "soupy" mix of potentially life-forming ("prebiotic") chemicals and water, results announced by a team of astronomers on April 7, 2009 from a new study suggests that planets around stars much cooler than our Sun, Sol, may have a significantly different mix of such chemicals. These worlds are quite out there (at least as far as our ability to travel goes). If other planets can support life chemically as we know it here on earth, how does this relate to the origin of life itself?
