Recently, NASA (NASA) Jet Propulsion Laboratory (Jet Propulsion Laboratory) announced that they use Kepler telescope found two planets to survive life may be appropriate. These two M-type red dwarfs are called K2-72c and K2-72e, about 181 light-years from Earth. Previously astronomers have announced the discovery of two & ldquo; the most likely date extrasolar planet suitable for human survival & rdquo ;.

The researchers found that the two M-type red dwarf with a temperature very close to the Earth, equivalent to 1.2 times the volume of the size of the Earth -1.5 times. The average temperature of the Earth K2-72c higher than expected 10%, while the average temperature K2-72e about 6% lower than the Earth. These two planets are in the & ldquo; the habitable zone & rdquo;, K2-72c orbital period of about 5.5 days, and the orbital period is about 24 days K2-72e.

This is the latest Kepler telescope observations K2 observation mission. Once named K2 planet, scientists will use these planets Kepler telescope's high-resolution images and use spectrophotometric techniques to determine the quality of these objects and other basic physical characteristics.

In addition, NASA is currently being assembled James & middot; Webb Space Telescope will be by infrared observations of the universe to help scientists learn more about the structure of the universe.

James & middot; Webb Space Telescope is expected to launch in 2018, the entire project will cost $ 8.8 billion.
