Kepler's search for Earth-size planets: questions, comments
This thread is intended for comments and questions regarding the Kepler mission and the updates published under the topic: NASA's Kepler to find Earth-size planets.

Kepler is a spaceborne telescope designed to search the nearby region of our galaxy for Earth-size planets orbiting in the habitable zone of stars like our sun. The habitable zone is the region around a star where temperatures permit water to be liquid on a planet's surface.

Liquid water is considered essential for the existence of life as we know it. The vast majority of the approximately 300 planets known to orbit other stars are much larger than Earth, and none is believed to be habitable.

The challenge for Kepler is to look at a large number of stars in order to statistically estimate the total number of Earth-size planets orbiting sun-like stars in the habitable zone. Kepler will survey more than 100,000 stars in our galaxy.

The Smithsonian's National Air and Space Museum Trophy for 2015 in the category of Current Achievement will be awarded to the NASA's Kepler Mission Team.
Established in 1985, the award recognizes outstanding achievements in the fields of aerospace science and technology and their history. As in past years, Trophy winners receive a miniature version of "The Web of Space," a sculpture by artist John Safer.

Kepler mission has confirmed the first near-Earth-size planet in the "habitable zone" around a sun-like star. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another "Earth."

The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030.
