A mineral that acts like a sponge beneath Earth's surface stores more oxygen than expected, keeping our planet from becoming dry and inhospitable like Mars. The key to the abundant oxygen storage is the mineral majorite, which exists deep below Earth's surface in the mantle. Without the oxygen stockpile, Earth would probably be a barren planet hostile to life. picked by AutumnLotus 2 years ago

With their high octane colours and incredible detail they look more like canvassed art than landscapes of the earth.

with my amazing 60% on our US citizenship score, i think i am the new leader of the pack unti those extra smart guys get back. in which case, we're all screwed anyway.

here's my fix. walk up the one in 5 of your friends who really truly believes that the sun revolves around the earth. then punch them. i think if you punch them often enough, they will come to their senses. picked by muppet 2 years ago

Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world’s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere. picked by AutumnLotus 2 years ago

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, ch... read full post picked by wags273 2 years ago

There is a growing body of evidence that suggests the Earth's magnetic field is about to disappear (at least for a while). As the magnetic poles shift position, it will have a significant effect on our terrestrial weather as well as all the gadgets we've launched into Earth orbit. picked by BrownTrout 3 years ago

This Thursday a rocket will take two new European telescopes into space, and park them not in an orbit around earth, but in an orbit around the sun.

Some crucial ingredients for life on Earth may have formed in interstellar space, rather than on the planet's surface. A new computer model indicates clouds of adenine molecules, a basic component of DNA, can form and survive the harsh conditions of space, and possibly sprinkle onto planets as the stars they orbit travel through a galaxy. picked by AutumnLotus 2 years ago
