Aliens Among Us!

March 6, 2013 An Otherworldly Discovery – Billions of Other Planets: Astronomers said Wednesday that each of the 100 billion stars in the Milky Way probably has at least one companion planet, on average, adding credence to the notion that planets are as common in the cosmos as grains of sand on the beach.

The finding underscores a fundamental shift in scientific understanding of planetary systems in the cosmos. Our own solar system, considered unique not so long ago, turns out to be just one among billions.

Until April 1994, there was no other known solar system, but the discoveries have slowly mounted since then: The Kepler space telescope, designed for planet-hunting, now finds them routinely.

Planets are the rule rather than the exception. An international team of 42 scientists spent six years surveying millions of stars at the heart of the Milky Way, in the most comprehensive effort yet to gauge the prevalence of planets in the galaxy.

To estimate the number of other worlds, Dr. Cassan and his colleagues studied 100 million stars between 3,000 and 25,000 light-years from Earth with gravitational microlensing. The technique uses distant light amplified by the gravity of a massive star or planet to create an astronomical magnifying lens. Then they combined their findings with earlier surveys, which used other detection techniques, to create a statistical sample of stars and the planets that orbit them, which they say is representative of the galaxy.

By their calculations, most of the Milky Way’s stars—100 billion is the most conservative estimate—have one or more planets. “One can point at almost any random star and say there are planets orbiting that star,” said astronomer Uffe Grae Jorgensen, of the University of Copenhagen in Denmark.

Moreover, millions of these planets may circle two stars; an arrangement considered so unlikely that until a few months ago it was found only in science fiction.

We are starting to see a whole new type of planetary system, which is unlike anything in our own solar system,” said William Welsh, an astronomer at San Diego State University.

The discoveries are the latest from an avalanche of new data about worlds around other stars.

We are now facing the idea that planets are all over the place,” said astrophysicist John Southworth at the U.K.’s Keele University, who wasn’t part of these research projects.

Astronomers using the Kepler telescope found the first known double-star planet just last September—Kepler-16b, a gassy oddball orb the size of Saturn that circles a pair of stars 200 light-years from Earth, like the planet Tatooine in the “Star Wars” films.

On Wednesday, Dr. Welsh and his colleagues announced that they have confirmed the existence of two more worlds in distinctive double-star solar systems in the constellation Cygnus. The first, called Kepler-34b, orbits its two small stars in a solar system about 4,900 light years from Earth. The second, Kepler-35b, orbits a set of twin stars about 5,400 light years away.

    Revelation talks about earth finally receiving her second star. I bet that would make land masses raise and fall.
