Whether out-of-the-box thinking or a sign of desperation, scientists on Wednesday proposed the regular transport of moon dust to a gravity point between Earth and Sun to temper the ravages of global warming.
Ideas for filtering solar radiation to keep Earth from overheating have been kicking around for decades, ranging from giant space-based screens to churning out reflective white clouds.

When NASA's Curiosity rover arrived at the "sulfate-bearing unit" last fall, scientists thought they'd seen the last evidence that lakes once covered this region of Mars. That's because the rock layers here formed in drier settings than regions explored earlier in the mission. The area's sulfates - salty minerals - are thought to have been left behind when water was drying to a trickle.

Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed.
The ring system is around a dwarf planet, named Quaoar, which is approximately half the size of Pluto and orbits the Sun beyond Neptune.
