Artificial Intelligence and NASA Data Used to Discover Eighth Planet Circling Distant Star


We now know of another planetary system with as many planets as our own. The discovery is an eighth planet orbiting a distant sun-like star called Kepler-90. All of the planets in the Kepler-90 system are closer to their star than the Earth is to the sun. Called Kepler-90i, the planet’s surface is 800˚F, making it unlikely that life as we know it could exist there. Researchers discovered the planet using data from NASA’s Kepler space telescope. Kepler measures the drop in brightness of stars as planets orbit in front of them. To find Kepler-90i, researchers trained computers to learn how to spot the faint signals of small planets. Success using techniques like machine learning mean that even more planets might be discovered using Kepler data.

    ..cool animations..

    This was just a long gif with music. Instead of weird captions, why not have someone actually read out the information? Isn't that was videos are good for?

    I understand that science is all about statistics but I'd like to make a few points about today's announcement.  This machine learning software was looking at archival data that humans didn't look at because of the weakness of the signal in the data.  Kepler telescope is a great piece of technology but the mirror isn't perfectly flat so there's some room for error just from the optics of the telescope.  The signal is measuring a dip in the sunlight of a star 2,500 light years away so basically every exoplanet discovered by man and machine could be a planet and a moon and their combined mass is causing the dip.  Now the machine looks at the data based on what it was told to look for and by using statistical formulae on data that humans haven't looked at yet it determined there was a 94.2% chance it was another planet.  It's great technology and the more it's used the better it will become and that data will be added to the human studied data for a more complete picture.  This won't be putting people out of work though so no worries there!  Congratulations to the teams and please keep up the good work, but let's be fair and say that a statistical analysis is the next best thing to a case study, therefore, it provides the 2nd best result!

    I don't understand… We already have 8 planets in our solar system then what does it mean '8th planet'?? Pls reply….

    Amazing!

    please use the AI to look for the nth planet of our solar system!!!!

  • space_artist_4real says:

    This planetary system is very intriguing because it's exactly how we believed solar systems were like before we had discovered exo planets: Earth-like, rocky planets are close to their star, gas giants are farther away because lighter gases are cleared out by of the solar wind… now we know gas giants usually orbit close to their sun (hot Jupiters), and our solar system is arranged quite uniquely. Hence, seeing the arrangement of the planets of this system really bothers me because it's clearly not ordinary.

    Anyone wants to confirm or completely demolish what I think?

    What an exciting news from NASA! Good work! Looking forward to seeing more of awesome announcements in the near future!

    God created beautiful things 😊 His beauty and wisdom are all around us 😊 Theres still more He made, but our human minds will never grasp it 😊 💖 Praise the Beautiful Lord amen!! 😊💖

    I only take exception to the description of the star as a "distant" star. The star is a mere 2,434 LY away. The Milky Way is over 100,000 LY wide. 99.9% of the stars IN JUST OUR GALAXY are further away from Earth than is this star and that doesn't begin to consider the billions of outer galaxies in the observable universe. "Distant" my foot. Considering the observable universe, this star is barely a stones throw away. Just imagine how many more there must be with similar planetary systems.

    So, my question to NASA Ames is: If the surface temperature of Kepler-90i is 800F, what would the surface temperature of earth be if earth was a dead planet without atmosphere or water or trees to get in the way ?

    Hi I have questions About the movement of the earth day and night .
    What happens if the earth stops rotating around itself?
    What happens to humans if the ground stops moving?
    Please send questions to space scientists and space science websites

    We all humans thought that water is nessasary for life but maybe this is not a truth maybe extraterritorial life is is on a planet which doesn't have sun we have to study again regarding this i request NASA to reveal a little bit (LITTLE-BIT) so that anybody on earth gives some tips to NASA maybe an ordinary man why NASA only believes in astronomy and scientists in my best views they should give chance maybe anybody help NASA which scientists not yet.it's my personal thoughts don't be take it so serious ok…
