NASA's Kepler Mission Finds Earth-size Planet Candidates in Habitable Zone, Six Planet System

Показать описание
NASA's Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet's surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun.

Kepler also found six confirmed planets orbiting a sun-like star, Kepler-11. This is the largest group of transiting planets orbiting a single star yet discovered outside our solar system. Located approximately 2,000 light years from Earth, Kepler-11 is the most tightly packed planetary system yet discovered. All six of its confirmed planets have orbits smaller than Venus, and five of the six have orbits smaller than Mercury's.

It's remarkable that the number of planets (whether habitable or not) orbiting other stars continues to steadily grow larger. The galaxy is an amazing place.

@EverettM1984...the Spitzer space telescope is an infrared telescope and cannot be used to spot such small objects (an Earth-sized planet) at extreme distances. The primary method of confirming these candidates is to use Earth-based telescopes to measure radial velocity, the small changes in a star's wobble as a planets orbits around it. The team is now doing those measurements. I don't know any additional status, but I think the team will be holding more news conferences later this summer.

I knew this day would come! I am very excited to see what more this discovery has to offfer.

This is very exciting. Just think in 5 years time how many discoveries will have been made!

wow!! 54 habitable zone candidates! that's awesome!

once we DO perfect rapid space travel, we'll have plenty of potential destinations lined up ^^

Do we have an update on those 5 earth-like candidates? Maybe from the Spitzer space telescope?

before my life ends... i would like us human being to discover another life in another planet.

Although I found this video interesting, since there were no thumbs down votes I had to give one in the name of science and the laws of probability.

based on drakes optimistic estimations assuming the suns has an average lifespan of 10billion years and remove 4billion years to give an optimistic estimation there is a chance of chance that we have discovered life and that is about as optimistic an result you get without loosing the ability to argue for the result^^

these planets may have life like us :o?

@TABOOVSKNOWLEDGE I'd say the average is more than that... but the vast majority of those would be large gas giants and rocky outer ice planets... Goldilocks zones are probably mostly empty space or uncleared detritis... perhaps one in ever 20 solar systems.

Thats still a HUGE number of earth sized, water covered and hopefully oxygen present worlds within a hundred light years or so! As fermi said in 1944 though... WHERE IS EVERYONE?

Actually; the science fiction writers; knew all along; those systems were out there. The scientists are just catching up. And while you are peeking at all those systems; keep an eye out for any optical pulses that could be A communication attempt; from another civilization.

Is there a lot of global warming in this new planetary system ?

We're still a predator species. We are not ready to meet other life forms.
