Kepler-22b New Planet With Earth-Like Characteristics Discovered In Habitable Zone thoughts
NASA's Kepler Confirms Its First Planet in Habitable Zone of Sun-like Star: Kepler 22-b (5/12/2011) thoughts
NASA's Kepler Mission Announces Latest Planetary Discovery
This is amazing news according to reports NASA announced the discovery of Kepler-22b this is great the first planet the Kepler spacecraft has discovered in the habitable zone, an area with a distance from a star where temperatures will permit the existence of liquid water.Reports say the discovery of Kepler-22b which is 600 light-years away from Earth, brings scientists one step closer to finding a planet that could possibly harbor life Earth may not be the only one This is a major milestone on the road to finding Earth's twins Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe Kepler-22b has several Earth-like characteristics according to reports The new planet's temperature is around 72 degrees Fahrenheit and its radius is 2.4 times Earth's. The planet completely orbits its star, which is similar to our sun, every 290 days, just 75 days shy of an Earth year Reports say that the National Optical Astronomy Observatory announced the discovery of Kepler-21b, a new planet with a radius 1.6 times Earth's. But unlike Kepler-21b, which is only about 3.7 million miles away from its sun and is therefore a scorching 2,960 degrees Fahrenheit, Kepler-22b is about 79 million miles from its sun, coming in at a pleasant 72 degrees.
it's not yet clear if Kepler-22b is composed or rock, gas or liquid according to reports.
Scientists use the Kepler spacecraft to discover new planets by analyzing extremely faint dips in light from far-away stars. These "dips" occur each time the planet passes between the Kepler and its sun, therefore obstructing the star's light. In order for a planet to be confirmed, scientists must observe the celestial body orbit its sun three times according to sources Kepler-22B takes 290 days to orbit its sun, it took nearly three Earth years for scientists to confirm that it was a planet.

The Kepler mission's science team announced its latest finding at a press conference on Monday, Dec. 5, 2011. The team announced the confirmation of Kepler-22b, its first planet found in the "habitable zone," the region where liquid water could exist on a planet's surface. The planet is about 2.4 times the radius of Earth, orbits around a star similar to our sun and is located 600 light-years away. Scientists don't yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets. The planet's host star belongs to the same class as our sun, called G-type, although it is slightly smaller and cooler.
Kepler also has discovered 1,094 new planet candidates, nearly doubling its previously known count. Since the last catalog was released in February, the number of planet candidates identified by Kepler has increased by 89 percent and now totals 2,326. Of these, 207 are approximately Earth-size, 680 are super Earth-size, 1,181 are Neptune-size, 203 are Jupiter-size and 55 are larger than Jupiter. The findings, based on observations conducted May 2009 to September 2010, show a dramatic increase in the numbers of smaller-size planet candidates.
