New helium discovery could boost the world’s dwindling supply

New helium discovery could boost the world’s dwindling supply A new discovery in the Tanzanian East African Rift Valley could loosen up supplies considerably, though.Scientists there have uncovered huge deposits of the gas in ancient volcanic rocks, and this could lead to more discoveries in the future.

Billion-year-old air has five times more oxygen than expected

Billion-year-old air has five times more oxygen than expected Scientists have, for the first time, been able to directly analyze the atmosphere of Earth from nearly a billion years ago.A team of Canadian researchers developed a technique to recover microscopic pockets of air from ancient salt crystals, and they reveal Earth had a lot more oxygen than we thought in those days.

Proposed Anthropocene epoch rustles jimmies of dissenting geologists

Proposed Anthropocene epoch rustles jimmies of dissenting geologists Enter the Anthropocene Epoch: the “new age of man.Other commenters confuse the Anthropocene epoch with the idea of anthropogenic climate change.

The supervolcano that may have killed off Europe's Neanderthals is stirring again

The supervolcano that may have killed off Europe's Neanderthals is stirring again The Phlegraean Fields (Italian: Campi Flegrei) are a series of craters and volcanic areas located near Naples, Italy.Like the Yellowstone caldera in the United States, the Phlegraean Fields have previously demonstrated a capacity for titanic eruptions.

Scientists identify missing mass in Earth's core

Scientists identify missing mass in Earth's core Contrary to what the money-losing 2003 film “The Core” would have you believe, we have no way to access the Earth’s core directly.Now, a new study from researchers at Tohoku University in Japan may have identified the core’s missing mass as silicon.

Debris from ancient asteroid explosion still peppering our planet

Debris from ancient asteroid explosion still peppering our planet At a time when terrestrial plant life was just beginning to take hold here on Earth some 466 million years ago, a massive asteroid collision happened someplace nearby.The University of Chicago team led by cosmochemist Philipp Heck were able to find ancient meteorite fragments from before the chondrite-forming event.

A new 'continent's' been found under the magical land of New Zealand

A new 'continent's' been found under the magical land of New Zealand An entire flipping continent might be hiding beneath New Zealand, geologists say.Yet most of it — about 94 percent — is submerged in the ocean, according to a new study in the Geological Society of America's journal, GSA Today.

India's only active volcano is back from the dead after 150 years

India's only active volcano is back from the dead after 150 years It erupted for about four hours in January, scientists from the National Institute of Oceanography (NIO) claimed.The volcano is situated in Barren Islands in the Andaman & Nicobar archipelago.

ISRO will now look for new bodies of water in India's Silicon Valley

ISRO will now look for new bodies of water in India's Silicon Valley The Indian Space Research Organisation (ISRO) recently set a world record by launching 104 satellites at one go, but their next venture will be discovering new lakes in India's Silicon Valley, according to reports.“When a water body gets dry, water has to find its own course and form new bodies elsewhere,“ KLCDA chief executive told The Economic Times.

Ancient fossils may hold the oldest known signs of life on Earth

Ancient fossils may hold the oldest known signs of life on Earth Ancient rocks in northwestern Canada may contain the oldest evidence of life on Earth.8 billion years ago near volcanic vents on the seafloor, according to a study published Wednesday in Nature.

Newly discovered rock formations could be fossils from earliest living organisms

Newly discovered rock formations could be fossils from earliest living organisms 5 billion years ago, and a new discovery in Canada indicates life developed not long after.28 billion years ago.

Please send me to Saturn's 'Death Star moon' so that I may climb its mountains

Please send me to Saturn's 'Death Star moon' so that I may climb its mountains New close-up photos of Saturn's "Death Star moon" Mimas show the world's untouched, craggy cliffs and craters calling out for exploration.Just imagine strapping on your hiking boots and bouncing across the tree-free, low-gravity landscape, checking out the alien moon's best views from above its pockmarked surface.

Ice age waterfalls caused the original 'Brexit,' scientists say

Ice age waterfalls caused the original 'Brexit,' scientists say But the island's original split from mainland Europe actually happened hundreds of thousands of years ago.Researchers have a new theory for how this prehistoric "Brexit" likely went down: first with an overflowing glacial lake, and later with a catastrophic flood.

Scientists Unravel the Mystery of Antarctica's Blood Falls

Scientists Unravel the Mystery of Antarctica's Blood Falls However, geologist Griffith Taylor was made of sterner stuff when he discovered Blood Falls in the early 1900s.This flow of red liquid on Taylor Glacier in Antarctica has been perplexing scientists since it was discovered, but they’ve finally figured it out.

Lightning Strikes Can Look an Awful Lot Like Meteors

Lightning Strikes Can Look an Awful Lot Like Meteors But when we look back through the geological record, we’re separated from the event by tens of thousands, if not millions of years.This puts a lot of strain on the rock and creates a special type of crystal known as shock quartz.

NASA's $3.5 billion plan could keep Yellowstone from ever erupting again

NASA's $3.5 billion plan could keep Yellowstone from ever erupting again An eruption in Yellowstone could be a global cataclysm, but NASA has a plan to reduce the risk while also generating power.The NASA plan involves drilling into the caldera from sites outside of Yellowstone to gain access to the magma pocket that powers the supervolcano.

Ancient Meteorite Impact Produced Highest Natural Temperature Ever On Earth

Ancient Meteorite Impact Produced Highest Natural Temperature Ever On Earth This 17-mile (28-kilometer) depression contains Mistastin Lake, which is quite obviously an impact crater when seen from above.There’s an arcuate central island in the lake, which is the central uplift of the original impact crater, and the lake itself is roughly circular.

The Oldest Rocks on Earth Could Contain Signs of Life

The Oldest Rocks on Earth Could Contain Signs of Life A team of Japanese scientists studying the oldest rocks on Earth has found new evidence to support the existence of life during the “Late Heavy Bombardment” period.These rocks are as old as 4 billion years, only half a billion younger than the Earth itself.

Yellowstone Supervolcano Could Erupt Sooner Than Expected

Yellowstone Supervolcano Could Erupt Sooner Than Expected Scientists have long expected it would take centuries for Yellowstone to transition to an active volcano again, but now they’re cutting that timeline down to as little as a few decades.The Yellowstone Caldera has erupted three times over the last 2.
