Turns out we've got some newly discovered neighbors in he Milky Way... a LOT of them.
Scientists have been going through data from the Kepler space telescope and have confirmed the existance of over twelve hundred new planets in our galaxy.
What's more, nine of those COULD be Earth-like.
To talk with me a bit more about this, I'm joined by Ed Krupp.
He's an Astronomer and the Director of the Griffith Observatory.
