This Is Big: Scientists Just Found Earth’s First-Cousin

Right now, 500 light years away from Earth, there’s a planet that looks a lot like our own. It is bathed in dim orangeish light, which at high noon is only as bright as the golden hour before sunset back home. 
NASA scientists are calling the planet Kepler-186f, and it’s unlike anything they’ve found. The big news: Kepler-186f is the closest relative to the Earth that researchers have discovered. 
It’s the first Earth-sized planet in the habitable zone of another star—the sweet spot between too-hot Mercury-like planets and too-cold Neptunes— and it is likely to give scientists their first real opportunity to seek life elsewhere in the universe. “It’s no longer in the realm of science fiction,” said Elisa Quintana, a researcher at the SETI Institute. 
But if there is indeed life on Kepler-186f, it may not look like what we have here. Given the redder wavelengths of light on the planet, vegetation there would sprout in hues of yellow and orange instead of green.

The Airbus Defence and Space agency has released images taken by both Pleiades satellites that show final stages of construction or renovation of all 12 stadiums to host the 2014 FIFA World Cup, in Brazil. The high resolution images were taken between 2012 and 2014 and are available for download here.

Lawrence Krauss on a scientific breakthrough that enables us to see the afterglow of the Big Bang: http://nyr.kr/No82A2

"For some people, the possibility that the laws of physics might illuminate even the creation of our own universe, without the need for supernatural intervention or any demonstration of purpose, is truly terrifying. But Monday’s announcement heralds the possible beginning of a new era, where even such cosmic existential questions are becoming accessible to experiment."
