Scientists discover a nearly Earth-sized planet: "By JENNIFER QUINN, Associated Press Writer Jennifer Quinn, Associated Press Writer – 1 hr 22 mins ago
HATFIELD, England – In the search for Earth-like planets, astronomers zeroed in Tuesday on two places that look awfully familiar to home. One is close to the right size. The other is in the right place. European researchers said they not only found the smallest exoplanet ever, called Gliese 581 e, but realized that a neighboring planet discovered earlier, Gliese 581 d, was in the prime habitable zone for potential life.
'The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the 'habitable zone,'' said Michel Mayor, an astrophysicist at Geneva University in Switzerland.
An American expert called the discovery of the tiny planet 'extraordinary.'
Gliese 581 e is only 1.9 times the size of Earth — while previous planets found outside our solar system are closer to the size of massive Jupiter, which NASA says could swallow more than 1,000 Earths.
Gliese 581 e sits close to the nearest star, making it too hot to support life. Still, Mayor said its discovery in a solar system 20 1/2 light years away from Earth is a 'good example that we are progressing in the detection of Earth-like planets.'
Scientists also discovered that the orbit of planet Gliese 581 d, which was found in 2007, was located within the 'habitable zone' — a region around a sun-like star that would allow water to be liquid on the planet's surface, Mayor said.
He spoke at a news conference Tuesday at the University of Hertfordshire during the European Week of Astronomy and Space Science.
Gliese 581 d is probably too large to be made only of rocky material, fellow astronomer and team member Stephane Udry"

School suck's whyu do you need to leran all the subject's anyway. Like if you want to become a pilot all you need to know is the history science and math. It's not like you need to know every subject.And what's up with homework it's just work from school that you brig home why do have to do if you don't understand it you will probbaly get all wrong.and then the next day you get an F.and then if why didn't have Home work we probbaly won't get but the next day you will probally know how to do it when the teacher explain's and get's further into the lesson.
