A reservoir of water three times the volume of all the oceans has been discovered deep beneath the Earth’s surface. The finding could help explain where Earth’s seas came from.
The water is hidden inside a blue rock that lies 700 kilometres underground in the mantle, the layer of hot rock between Earth’s surface and its core.
Some geologists think water arrived in comets as they struck planets, but the new discovery supports an alternative idea that the ocean oozed out of Earth’s interior layer.
OH MY GODDDDDDD -NERDS OUT-
That’s where the lizard people live
I am mad excited for the new N.K Jemisin joint, but like Dragon Age Inquisition, it eludes me until 2014 (August to be exact). The cover and title was just revealed. Up until now I only knew it as “the Untitled Magic Seismology Project.”
This is her talking about the then “work in progress” book last year:
So many of my story ideas come to me as visual flashes or dream images that I must then build worlds and storylines make sense of. I don’t actually remember where this one came from — my brain works like that — but it lodged in my head and I can’t shake it. The image is of a middle-aged woman doing a menacing stroll across a gray, ash-flecked plain, with a black-glass knife in one hand… and a mountain hovering above and behind her. Out of that I’ve spun (the first 50,000 words so far of) a tale of a seismically hyperactive world in which all life, and magic, has configured itself around surviving catastrophic earthquakes and apocalyptic volcanic winters. The woman is Essun, an orogene, born with the ability to control seismic activity. She’s looking for her husband, who’s just murdered their son and kidnapped their daughter, but finding him will be a bit difficult. That’s because the worst and perhaps last volcanic winter that humanity will ever face has just begun, and factions are already forming among the survivors. Essun’s private war will have to wait as a much bigger war begins to brew and she is forced to choose sides between her fellow orogenes — the very people who destroyed the world — and ordinary humans — who kill and enslave her kind whenever possible.
I highly recommend "The Inheritance Trilogy" and "The Dreamblood." Those links include free samples of the first chapters of each book, if you need some good fantasy in your life that isn’t just another Medieval Europe wank.
There have been over 90 recorded cases of amphibians being found alive but fully encased in coal pockets or stone geodes. Of these cases, 40 involved frogs or toads. After a few minutes exposed to air it comes-to-life In most cases the animal dies with 24-72 hours but there are some references that when these poor creatures were quickly allowed into fresh pond water they seem to have survived indefinitely.
Necromancer a couple millenia ago was just like.
" you know what’d freak some miners out?"
Sci Fi as fuck
comedy equals tragedy plus time so it’s actually pretty funny when you think about it
Hexagonal rocks-WUT: The columns form due to stress as the lava cools. The lava contracts as it cools, forming cracks. Once the crack develops it continues to grow. The growth is perpendicular to the surface of the flow. Entablature is probably the result of cooling caused by fresh lava being covered by water. The flood basalts probably damned rivers. When the rivers returned the water seeped down the cracks in the cooling lava and caused rapid cooling from the surface downward. The division of colonnade and entablature is the result of slow cooling from the base upward and rapid cooling from the top downward. (via Hexagonal rocks)

A New Perspective of the Day: This is What a Volcanic Eruption Looks Like from Space
Here’s a striking view of Sarychev Volcano in Kuril Islands of Japan going through its early stage of eruption, taken from the orbit of the International Space Station in June 2009. For more info on this picture, head over to NASA’s Earth Observatory!
New Delhi: Scientists at the Indian Space Research Organization have discovered a giant underground chamber on the moon, which they feel could be used as a base by astronauts on future manned missions to moon.
An analysis by an instrument on Chandrayaan-1 revealed a 1.7-km long and 120-metre wide cave near the moon’s equator that is in the Oceanus Procellarum area of the moon that could be a suitable ‘base station’ for future human missions.
Scientists of the Space Applications Centre in Ahmedabad said in a research paper published in the latest issue of Current Science that the cave provides “a safe environment from hazardous radiations, micro-meteoritic impacts, extreme temperatures and dust storms.”
Scientists said identifying sites for permanent base for human settlements on the moon is important for further exploration.
"Lava tubes provide a natural environmental control with a nearly constant temperature of minus 20 degrees Celsius, unlike that of the lunar surface showing extreme variation, maximum of 130 degrees Celsius to a minimum of minus 180 degrees Celsius in its diurnal (day-night) cycle," they said.
According to them, the lava tubes offer a dust-free environment and adapting them for human use requires minimal construction.
