The night sky lit up as NASA‘s Kepler telescope rocketed into the atmosphere above Cape Canaveral, 1 Thousands of people watched the launch from Earth. But was anyone watching from space? The Kepler space telescope will help answer that question. When the telescope blasted into space, it became part of the 2 first space mission dedicated 3 for Earthlike planets.
The telescope is named for Johannes Kepler, the 16th century German astronomer who discovered that planets orbit in an oval-shaped path 4 circles, as was believed 5 Kepler was first to suggest that the sun rotates on its axis. He was also the first to correctly explain how vision and telescopes work, and he helped 6 Galileo’s theories.
Kepler carries the largest camera ever launched into orbit. The camera will look for planets by studying regular dips in the brightness of stars. 7 If Kepler were to look down at a small town on Earth at night from space, 8 it would be able to detect the dimming of a porch light as someone passed in front. 
Kepler is designed to find planets that are like ours. These planets would have rocky cores and would be about the size of Earth. They would also be the right temperature to have liquid 10 for life resembling that found on earth. 11 explains Lia LaPiana, who works on NASA‘s Kepler team. If a planet is too close to a star, the temperature is too high. If it’s too far away, it is too low.
The mission 12 as a planetary census. However, Kepler will only examine a small wedge of space. The telescope itself cannot detect life forms. It can only identify planets where the presence of life is possible 13 The NASA team will study the data about those planets and look for more clues. Future spacecraft may be sent to follow up.
Even if Kepler fails to make any promising sightings, the mission will have been a success. 14 Earthlike planets found in the habitable zone would be a pretty strong indication that the way our solar system is formed is very rare.
