    Large earthquakes aren’t supposed to happen in Tennessee. On Wednesday, the largest earthquake in 45 years hit eastern Tennessee, and it made headlines all over the nation. The magnitude 4.4 quake was so powerful that it was felt in portions of Alabama, Georgia, South Carolina, North Carolina and Kentucky. Significant shaking was even felt as far away as Atlanta, and that was highly unusual. The original earthquake was rapidly followed by a magnitude 3.0 aftershock, and subsequently there were several other noteworthy aftershocks. We live at a time when earthquakes are increasing in size and frequency, and many are concerned...

    The climate model simulations used in the study reveal changes in sea surface and prevailing winds during the last glacial maximum of the most recent ice age as well as for future climate conditions. Credit: Pedro DiNezio The Indian Ocean played a far greater role in driving climate change during the last ice age than previously believed and may disrupt climate again in the future. That's according to a new study from The University of Texas at Austin, the findings of which could rewrite established Pacific-centric theories on tropical climate change. "The processes we have uncovered are particularly important for...

    “Climate change can seem like a distant problem, a speck on the horizon. It’s not. It’s a present and deadly reality.” These words were recently printed by the Huffington Post. “Common sense dictates that the economy undergo a massive restructuring away from fossil fuels to save lives. And a growing body of research shows that the only way to avoid catastrophic levels of climate change is to cease production of vast amounts of “unburnable” carbon. The only problem with this is that it is based on the assumption that carbon is a warming gas that is heating the planet. Every...

    About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova some 150 light years away from Earth. Within a few hundred years, long after the strange light in the sky had dwindled, a tsunami of cosmic energy from that same shattering star explosion could have reached our planet and pummeled the atmosphere, touching off climate change and triggering mass extinctions of large ocean animals, including a shark species that was the size of a school bus. The effects of such a supernova—and possibly more than...

    Barely living "zombie" bacteria and other forms of life constitute an immense amount of carbon deep within Earth's subsurface—245 to 385 times greater than the carbon mass of all humans on the surface, according to scientists nearing the end of a 10-year international collaboration to reveal Earth's innermost secrets. On the eve of the American Geophysical Union's annual meeting, scientists with the Deep Carbon Observatory today reported several transformational discoveries, including how much and what kinds of life exist in the deep subsurface under the greatest extremes of pressure, temperature, and low nutrient availability.Drilling 2.5 kilometers into the seafloor, and...

    We may still be looking for proof that aliens exist, but new research into some very curious ancient tools now reveals that humans were using extraterrestrial material long before mankind even dreamed of flying out of Earth’s atmosphere. The findings, which were published in the Journal of Archaeological Science, reveal that some incredibly old iron artifacts date to a time well before humans had the technological wit to smelt iron ore, and as it turns out, the iron used in their construction actually fell from the sky. Archaeologists have long suspected that the iron occasionally found amongst Bronze Age artifacts...

    King Tut owned a dagger that was out of this world—literally. Researchers have recently published a study in the journal Meteoritics & Planetary Science that supports what has long been suspected: The ancient Egyptians were using meteoritic iron well before the spread of iron smelting technology. The recent study on King Tut’s dagger, led by researchers from Italy and Egypt, used X-ray fluorescence (XRF) spectrometry to analyze the composition of the iron blade. Iron meteorites mostly contain iron and nickel, and the results of the XRF analysis on King Tut’s dagger confirm that the blade is mostly composed of iron...

    Italian and Egyptian researchers analyzed the metal with an X-ray fluorescence spectrometer to determine its chemical composition, and found its high nickel content, along with its levels of cobalt, “strongly suggests an extraterrestrial origin”. They compared the composition to known meteorites within 2,000km around the Red Sea coast of Egypt, and found similar levels in one meteorite.
  • Volcanoes are Fed by ‘Mush’ Reservoirs, Says New Study

    In order to erupt, volcanoes need a source of magma — melted, liquid rock — containing relatively few solid crystals. Traditionally, this magma was thought to be formed and stored in a magma chamber. Recent studies of magma chemistry have challenged this view, leading to the suggestion of the 'mush' reservoir model, where smaller pools of magma sit in the small gaps between solid crystals. However, the mush reservoir model could not explain how magmas containing relatively few crystals arise and are delivered to volcanoes in order for them to erupt at the surface. Now, with sophisticated modeling of mush...

    CAPE CANAVERAL, Fla. (Reuters) - A U.S. space probe was cleared for launch on Thursday to collect and return samples from an asteroid in hopes of learning more about the origins of life on Earth and perhaps elsewhere in the solar system, NASA said on Tuesday. A United Launch Alliance Atlas 5 rocket was scheduled to blast off from Cape Canaveral Air Force Station in Florida to dispatch the robot explorer Osiris-Rex on a seven-year mission. United Launch Alliance is a partnership of Lockheed-Martin and Boeing. Osiris-Rex is headed to a 1,640-foot (500-meter) wide asteroid named Bennu, which circles the...

    Paging Bruce Willis! NASA is planning to launch a probe to study an asteroid that could one day pulverize the Earth. The asteroid, named Bennu, crosses Earth’s orbit once every six years and has gotten ever closer since it was discovered in 1999, astronomers told the Sunday Times of London (paywall). In 2135, Bennu will fly between the moon and Earth — a hair’s breadth in space terms, the Times reported. That’s so close that gravity from the Earth could effect Bennu’s orbit, “potentially putting it on course for the Earth later that century,” said Dante Lauretta, a professor of...

    If human-induced climate change continues unchecked, 10 percent of the U.S. economy could evaporate by 2100, a 1,656-page federal report the White House slipped out on Black Friday (Nov. 23) warned — but a nearby world has an even hotter climate problem than ours, and scientists say we could learn some valuable lessons from it. That world is Venus, Earth's "evil twin," which was once nice enough — until something went wrong and the atmosphere began trapping a little too much heat. Scientists aren't positive precisely how events played out, but the runaway greenhouse effect that resulted is beyond debate:...

    Now, with a suite of high-tech hardware at its disposal, a company called Merlin Burrows believes it might have finally pinpointed the location where the city once stood.... Bruce Blackburn says his company used satellite data to comb an area that the group believed may have been the location of the thriving city. Their work began years ago and, according to Blackburn, the location was chosen based on Plato’s writings as well as other texts. The spot, which is located near the coast in Spain’s Doñana National Park, was subsequently searched for clues. Merlin Burrows says it was then that...

    Gravity is big and weird and difficult to study. It moves through space as a wave, sort of like how light does. But these waves are subtle and difficult to detect. They occur in measurable amounts only after massive events, like the collision of black holes. Humanity didn't spot its first gravitational wave until 2015. Then, in 2017, astronomers for the first time detected both gravitational waves and light from a single event: a neutron star collision. Now, researchers are using data from that event to confirm some basic facts about the universe. In a paper first uploaded Nov. 1...

    On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world. The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. The waves buzzed across Africa, ringing sensors in Zambia, Kenya, and Ethiopia. They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away. These waves didn't just zip by; they rang for more than 20 minutes. And yet, it seems, no human felt them. Only one person noticed the odd signal on the...

    Scientists have found that a "superheated blast from the skies" destroyed cities near the Dead Sea 3,700 years ago, which biblical analysts are saying echoes the destruction of Sodom.Science News reported that the new findings were revealed at the annual meeting of the American Schools of Oriental Research last week by archaeologist Phillip Silvia of Trinity Southwest University in Albuquerque, New Mexico. The scientists discovered radiocarbon dating and unearthed minerals that instantly crystallized at high temperatures at what used to be cities and farming settlements north of the Dead Sea, suggesting that a massive air-burst, possibly by a meteor, destroyed...

    The airburst "in an instant, devastated approximately 500 km2 [about 200 square miles] immediately north of the Dead Sea, not only wiping out 100 percent of the [cities] and towns, but also stripping agricultural soils from once-fertile fields and covering the eastern Middle Ghor with a super-heated brine of Dead Sea anhydride salts pushed over the landscape by the event's frontal shock waves," the researchers wrote in the abstract for a paper that was presented at the American Schools of Oriental Research annual meeting held in Denver Nov. 14 to 17. Anhydride salts are a mix of salt and sulfates....
