Gliese 581g is part of a string of planets in the Gliese 581 solar system. Two of Gliese 581g's siblings - Gliese 581e and Gliese 581b - orbit too close to their parent star to support any kind of life on them.
Io [EYE-oh or EE-oh] is the most volcanic world in the Solar System, and scientists think it's because of a torrid reservoir of magma under the crust at least 30km (50 miles) thick.
It is a space mission 33 years in the making: The Voyager 1 spacecraft will cross a boundary not yet crossed before. It will leave our solar system and enter interstellar space.

One of the largest highly non-spherical bodies in the solar system, Hyperion has an irregular shape, chaotic rotation and unexplained sponge-like appearance.
Planets that orbit too close to or too far away from their stars do not have a suitable climate; this can only be found in a slender strip of solar space around each star known to astronomers as a 'habitable zone'.
Low-Earth Orbiting satellites are designed to withstand a regular onslaught of solar energy, but a rare "solar megastorm" could decimate a majority of the fleet.

The Zephyr, a solar powered airplane, recently smashed the record for absolute duration of an unmanned autonomous vehicle, staying aloft for 336 hours and 22 minutes.
Tokelau, which consists of three small Pacific atolls administered by New Zealand, gets 93% of its electricity from solar panels, and the other 7% from a sustainable supply of coconuts.

Ito's architecture creates fluidity between nature and humanity. When people enter his completely solar-powered stadium in Kaohsiung, Taiwan, for example, he wants them to be able to feel the wind and feel the air.

Total eclipses leave just a solar corona visible, though when the apparent size of the moon is smaller than the sun, a bright annulus will surround the moon instead.
Regiments in Afghanistan are testing new solar energy panels. Marines praised the panels for being durable, light and simple, the trifecta for field gear.

BrightSource Energy is building a giant solar plant in the Mojave Desert, but before they do they are tasked with relocating the Desert Tortoise, a rare species, to animal preserves.
