Hum Posted January 11, 2012 Share Posted January 11, 2012 Researchers have concluded that each star in the Milky Way galaxy likely has at least one planet orbiting it, meaning that our galaxy has at least 100 billion planets to its name. Using a technique called microlensing, and statistical analysis applied to six years' worth of observations from the PLANET (Probing Lensing Anomalies NETwork), MOA (Microlensing Observations in Astrophysics) and OGLE (Optical Gravitational Lensing Experiment) surveys, researchers were able to determine that statistically speaking, every star in the Milky Way should have at least one orbiting planet, if not more. Moreover, these planets are likelier to have low masses, similar to Earth, than Jupiter-like masses. "We used to think that the Earth might be unique in our galaxy. But now it seems that there are literally billions of planets with masses similar to Earth orbiting stars in the Milky Way," says Daniel Kubas, co-author of a paper on the subject released in the journal Nature, in a statement. The microlensing technique uses the motion of stars and their gravity: when one star moves in front of another, it acts like a lens, magnifying the light from the background star. If there's a planet in orbit around the foreground star, it can further magnify the light. It's that extra boost that reveals the planet itself, which would otherwise be too faint to see through a telescope. Microlensing also reveals the mass of the planet, but doesn't really indicate what the world is composed of. These findings, reported by an international team of astronomers, are supported by data from two other planet-finding techniques, that is, detection of a planet's gravitational pull, or the dimming of a star as a planet passes in front of it. Taken together, the three techniques indicate that planets are pretty common in the Milky Way, and that there are more small planets than massive ones. source Link to comment Share on other sites More sharing options...
jakem1 Posted January 11, 2012 Share Posted January 11, 2012 Seems like a nice round number :) FMH 1 Share Link to comment Share on other sites More sharing options...
devHead Posted January 11, 2012 Share Posted January 11, 2012 That's pretty call. I wonder how many though can support life? It's been discovered that even our position in our galaxy (our solar system) is the called the "goldilocks spot". Link to comment Share on other sites More sharing options...

Farstrider Posted January 11, 2012 Share Posted January 11, 2012 .. and then one day "they" will discover that there are even more..! Also this is one galaxy, it's pretty amazing to think that there are hundreds of billions galaxies in the universe! Link to comment Share on other sites More sharing options...

neufuse Veteran Posted January 11, 2012 Veteran Share Posted January 11, 2012 and not one of them is capable of supporting life except ours! *tries not to laugh* :rofl: you gota think that at least one of those planets had an intelligent life form evolve thousands or tens of thousands of years or more before we became what we are... and who's to think what they figured out that we haven't even dreamed of yet Link to comment Share on other sites More sharing options...
Ently Posted January 11, 2012 Share Posted January 11, 2012 I can't believe that in our universes short existence of only 6000 years this many planets have formed. Space continues to amaze me! Link to comment Share on other sites More sharing options...

Well it shouldn't amaze you too much, they were all formed at once. More amazing is how they all balance on the back of that turtle. :laugh: Link to comment Share on other sites More sharing options...
