Rainwater will be stored under the Effel Tower and used for tap water in the restrooms. Ninety-five per cent of the new lighting will be LED-type, which has a longer lifespan and low consumption.
Technicians have set out into US national parks to document the natural noises of the park, as well as ambient human noise, an audible invasion that may be stressful to wildlife.
The organizers behind Earth Hour urge people to turn off lights in a symbolic show of support for action against climate change and for energy conservation.
Zero gravity flights and head spinning sessions in a centrifuge – creating gravitation forces eight times those on Earth – might have been enough to deter lesser citizens.
Astronomers believe super-Earths are the most abundant planets in our galaxy. The term describes any world heavier than Earth but not as massive as gas giants like Saturn and Jupiter.
The Haitian government has restored the iconic Cine Triomphe in Port-au-Prince. The movie theater's inauguration is especially profound, as no cinemas have operated in Haiti since the devastating 2010 earthquake.

The dish will direct the radio waves down into the heart of the receiver, where signals from deep space can be amplified, recorded and analysed. To compensate for the rotation of the Earth, it will need to be fully steerable.
Another way to gather information would be to transport a vessel to and from the planet. The technology exists to do this, but at 20 light years from the Earth, it would take 200 years for astronomers to receive the result.
Planets become stuck with one side always facing the star, just like the Moon and the Earth. Because of this, it is likely that Gliese 581g has permanent daytime on the side facing the star and permanent shadow on the other.
The comparisons between the Earth and Gliese 581g should not be overstated, however. Even if Gliese 581g can sustain organisms, it would be a very different place to live.
Planets that grow beyond 10 times the size of the Earth tend to become gaseous and uninhabitable, without the solid or liquid infrastructure necessary for organisms.
Like the Earth, Gliese 581g is also the right size for organic life. It is about 3.1 to 4.3 times the size of the Earth, and this relatively low mass means it should be made mostly of rock.
The white, cloudy contrails that airplanes often leave in the sky may be full of ice crystals, but they're warming the globe. They trap infrared radiation on its way out into space which slightly heats the Earth.
In the movie Skyline, strange lights descend on Los Angeles, drawing people outside like moths to a flame. An extra-terrestrial force threatens to swallow the entire human population off the face of the earth.

In 2011, 9.5 million Kenyans were affected by severe drought. Few people dreamt that two years later enough water to supply the entire country for seventy years would be discovered beneath the sun-scorched, cracked earth.
