Taken a picture on June the 1st and Jan 1st and then combined them with computers? Or used 2 satelites? 'tis ~6150 ly away. Neither options would make much, if any, difference to the angle we could view it from otherwise the star constellations which are much closer would make even less sense depending on when you saw them.I am dizzy now, fuck off space |

http://news.harvard.edu/gazette/story/2 ... s-surface/ Quote: Astronomers have found a planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth for liquid water to theoretically exist on their surfaces. In our solar system, only one planet is blessed with an ocean: Earth. Our home world is a rare, blue jewel compared with the deserts of Mercury, Venus, and Mars. But what if our sun had not one but two habitable ocean worlds? Astronomers have found such a planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth that liquid water could theoretically exist on their surfaces. Modeling by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) suggests that both planets are water worlds, their surfaces completely covered by a global ocean with no land in sight. “These planets are unlike anything in our solar system. They have endless oceans,” said lead author Lisa Kaltenegger of the Max Planck Institute for Astronomy and the CfA. “There may be life there, but could it be technology-based like ours? Life on these worlds would be under water with no easy access to metals, to electricity, or fire for metallurgy. Nonetheless, these worlds will still be beautiful, blue planets circling an orange star — and maybe life’s inventiveness to get to a technology stage will surprise us.” Kepler-62 is a type K star slightly smaller and cooler than our sun. The two water worlds, designated Kepler-62e and -62f, orbit the star every 122 and 267 days, respectively. They were found by NASA’s Kepler spacecraft, which detects planets that transit, or cross the face of, their host star. Measuring a transit tells astronomers the size of the planet relative to its star. Kepler-62e is 60 percent larger than Earth, while Kepler-62f is about 40 percent larger, making both of them “super-Earths.” They are too small for their masses to be measured, but astronomers expect them to be composed of rock and water, without a significant gaseous envelope. As the warmer of the two worlds, Kepler-62e would have a bit more clouds than Earth, according to computer models. More distant Kepler-62f would need the greenhouse effect from plenty of carbon dioxide to warm it enough to host an ocean. Otherwise, it might become an ice-covered snowball. “Kepler-62e probably has a very cloudy sky and is warm and humid all the way to the polar regions. Kepler-62f would be cooler, but still potentially life-friendly,” said Harvard astronomer and co-author Dimitar Sasselov. “The good news is — the two would exhibit distinctly different colors and make our search for signatures of life easier on such planets in the near future,” he added. The discovery raises the intriguing possibility that some star in our galaxy might be circled by two Earth-like worlds — planets with oceans and continents, where technologically advanced life could develop. “Imagine looking through a telescope to see another world with life just a few million miles from your own. Or, having the capability to travel between them on a regular basis. I can’t think of a more powerful motivation to become a space-faring society,” said Sasselov. Kaltenegger and Sasselov’s research has been accepted for publication in The Astrophysical Journal. Quote: In our solar system, only one planet is blessed with an ocean: Earth. Earth? Man, they really got my hopes up, there! FFS. |

Ah, nice post. Cheers. Imagine a planet of just water! On top of land I mean. I bet they have all kinds of cool civilisations powered by hot springs and stuff. |

I hope we never meet an alien race or we'll be forced to admit the lack of imagination that led to us calling our planets moon, "the moon" and our sun, "the sun". Frankly as a species it makes us look rather dim. |

What should we call them instead? I vote the moon be changed to Dave and the sun should be renamed Jerry Lee Lewis. |

You know, because to them, they are just the moon and sun. |

What do you think we would have would up calling them if we had two moons/suns? |
