NASA Discover 26 New Planets Outside Solar System

The size of the new planets discovered that NASA team varies. There is a little larger than the Earth to the larger of the giant planet Jupiter in our solar system. The planets discovered by Kepler space telescope to monitor the 150 000 stars in a small part of the night sky from its orbit around the sun. 

Alien planets that orbit their stars, which is larger than the Sun, once every six to 143 days. In the solar system's largest newly discovered, called Kepler-33, there are five planets with sizes ranging from one half to five times the size of Earth. 

Doug Hudgins, Kepler mission program scientist, said scientists are not convinced that the new planets found it capable of supporting life. 


"All the planets were in orbit that is closer than the Earth's orbit around the sun. So the planets were pretty hot," he explained. 
In the two years since Kepler began to observe the universe, scientists have discovered 61 new planets, planet and about 2,300 candidates who need to be confirmed by further observations. 

Kepler identifies the planets of distant stars by continuing to monitor the brightness of the diorbitnya. A planet orbiting the sun form a blurred image that can be detected by Kepler. 

The telescope's planetary candidates confirmed by measuring the so-called Transit Time or TTV variation that occurs when two or more planets in our solar system orbiting a dense their stars. 

Gravitational pull of each planet that passes makes the other planets move faster while others slow planet. According to Hudgins, are helping astronomers confirmed the observation of the planet.He said, "If there is something that only imitate the passage of one planet, they will not interact. That we see this transit timing variations indicate that there is an interaction of gravity and that they must have planets 
 because they interact with each other." 


Hudgins said it takes the planet hunters is a telescope that can separate the planet light is much fainter than the bright star, allowing scientists to study the electromagnetic spectrum. 

Information of the light spectrum will show what is contained in a gas atmosphere of the planet, maybe even some of the characteristics of its surface, said Hudgins is eager to find signs of life. 

"That's why we do this. That's an interesting thing. We studied one of the most oldest and most basic, are we alone in the universe?" he said again. 

Hudgins believes that such telescopes will be made in the near future, allowing scientists to move to the Kepler mission next stage of their findings.
