NASA announces discovery of 2 new planets

An artist's rendering shows two Saturn-sized planets discovered by NASA’s Kepler mission.

NASA has announced the discovery of two planets, slightly smaller than Saturn, orbiting the same star in the Milky Way, which have been discovered by the Kepler Space Telescope.

William Borucki, the Kepler Mission Science Principal Investigator, at the NASA Ames Research Center, announced on a teleconference "the first discovery of multiple planets orbiting the same star."

The two planets, known as Kepler 9B and 9C, have a clear gravitational interaction, according to NASA.

A third celestial body, has also been discovered. It's about 1.5 times the size of Earth, but it has not yet, been confirmed as a planet.

"The discovery incorporates seven months of observations of more than 156,000 stars as part of an ongoing search for Earth-sized planets outside our solar system," NASA said in a press release.

      No, spend more money on securing a better future for all humanity. I think discovering the Americas was a better investment than war and the rest of the budget of the old world.

    Two unnecessary commas, CNN? Really? I am appalled.

    NASA can find two planets outside the solar system but they cannot find Planet X which has been INSIDE the solar system since 2003?

    And before you say Planet X is a myth, please realize that MANY people have seen it with their own eyes, there are now many pictures of it taken by ordinary people on the internet, and there are MANY pictures of Planet X taken by NASA, SOHO, JPL and LASCO telescopes and other instruments above the earth. What? You have not seen these pictures? That is right: The biggest cover up in history is going on now, all so that YOU do not learn the truth and prepare before it is too late. (No need to worry about the power elite: They have made their bunkers and stocked them with 20 years' of supplies already.)

    Why would they cover up the existence of a planet X? Planet X was first thought up because of uranus had an orbit that couldn't be explained at the time. However currently we have found the explanation for this not involving a planet. Also yours trying to say that people have taken pictures of this? The planet is to far away

    "The first discovery of multiple planets orbiting the same star."
    Um... don't all the planets in our solar system orbit the sun? And isn't the sun a star?
    Or does that quote not mean what I think it means?

    Yes, NASA, we know there are many planets out there but when are you going to stop jerking us around and tell us about the extraterrestrials out there? Some of us have seen their craft at close range, so you cant go on with this charade forever. It is better to be truthful and inform the people of their existence, just in case a ship lands unexpectedly, which could cause a dangerous panic if folks are unprepared and ignorant. The people deserve to know the truth and to be prepared for contact beforehand!

    Reading most of these comments hurt my brain people are so ignorant. Trying to find life on another planet is a waste of tax payers money? Do you have a brain? Humans strive to know if we are the only ones out there and since the first caveman walked the earth he lived to discover and learn. It's natural instant to explore, now tell me how is that a waste of money?
