Citizen Scientists may have found two new Earth-like planets, usingPlanet Hunters

Citizen Science made an amazing leap this week . Citizen scientists , using the data supplied by theKepler public archives , help to identify two possible satellite outside of our solar organization , thanks to the web web browser gamePlanet Hunters .

The 10 best candidates as sifted through by citizen scientists during the first month afterPlanet Hunterswent live were passed onto the Kepler team , a group of scientists all over the world looking to find excess - solar planet , for further inquiry . The resultant role were publish in the articlePlanet Hunter : The First Two Planet Candidates key by the Public using the Kepler Public Archive Data , published in the daybook Monthly Notices of the Royal Astronomical Society this hebdomad .

NASA ’ Kepler Mission to line up Earth - like planet Orbiting other Stars

Launched in 2009 and revolve for a minimum of three years , theKepler Space Telescopeis concentrate on a group of 200,000 plus mavin near the constellation Cygnus in hope of finding inhabitable , Earth - like planets . Kepler wait at these stars , choose scant measuring every thirty second in hopes of finding a slight dimming in light intensity . This generated a tremendous amount of data , but data that can be used to generated light curves that convey how the light from a star can vary over a menstruation of several month .

Planet Hunters Game Play

Planet Hunters works by using an collateral access to finding planets , making manipulation of the Transit Method and the Kepler Public Data archive . By watch the spark emit by stars over a 30 + day period , user are ask to front for clip when the light curve ball “ dips ” in signal . This dip in signal , called a passage feature , suggests that a potential planet in orbit around the star is proceed across the way of the star at the time . It select about three hr for a major planet to move across the face of the star during its orbit , long enough for hundreds of light measurement to be made , result in dips scream transits . Your challenge , as a player , is to identify these dips in promiscuous intensity level over a row of time for a reach sensation . Also , the size of the major planet play a role , so if a major planet is very big , the depth of the transit will be large than that of a modest satellite , as the large major planet would blockade more light .

Why use Citizen Scientists ?

There is simply too much data for the Kepler Team to sift through one by one . Kepler monitors 200,000 stars and takes paradigm every thirty second gear , with the light curve generated need to be check by several eye before a consensus can be reached . Opening up the datum to citizen scientists allow 1000 of mortal to sieve through the data , acting like a jumbo supercomputer , and you to help await for satellite outside of our solar system . Each user name that took part in dissect the data that was report in the paper also had their name include in the acknowledgements section of the newspaper publisher . Planet Huntershas grown to go with more than 40,000 user , with over four million observance made on the data sets and 69 potential planets discover , which the Kepler Team will now look into . A new set of public reflection datum from Kepler , the third in the serial so far forPlanet Hunters , was released last hebdomad .
