Where's Tyche, the 10th 9th planet? Getting the full story.
John Matese and Daniel Whitmire of the University of Louisiana at Lafayette recently made the news when they announced the possible discovery of a gas giant planet they named Tyche
in the Oort Cloud, at the extreme edge of the Solar System (previously
). Now ars electronica breaks down the evidence behind the announcement, what can be done to confirm or disprove its existence & how long it could take.

People have been upset
about Pluto's demotion for some time now. (While classical music fans
have just had a love/hate relationship with this whole process.) But astronomical hate mail
has never been as cute as the missives Neil deGrasse Tyson has received over the years from tots upset at poor Pluto's ouster.

Tonight NASA is scheduled to launch the Kepler Mission
(named after planetary legislator Johannes Kepler
) with the goal of finding Earth size planets in orbit around stars in the Cygnus-Lyra
region of the sky. Over the next 3 and a half years it will maintain a nearly unblinking gaze on the approximately 100 thousand stars in the region. NASA expects it to find about 50 Earth size planets
, as well as hundreds that are larger. You can watch the launch live on NASA TV
. [more inside]

Hey, Baby -- did you feel that?
The sun, someday, will envelope the Earth and all life as we know it will die. Can we prevent this? Some wacky scientists think that the best thing to do would be to up and move the whole damn planet.

The Big Re-run?
"In the first millionth of a second after the universe’s
beginning, the entire cosmos consisted of this ultradense,
ultrahot brew, scientists say." And now scientists are trying to re-enact the Big Bang. Too big of a task to take on?

We are not alone....
a new planet outside of our solar system was found today. It's only a matter of time before the little green men come down to greet us.
