As the solar system was developing, the giant planets (Jupiter and Saturn) formed very early, and as they grew, they migrated both closer to and further away from the sun to stay in gravitationally stable orbits. The gravitational effect of these massive objects caused immense reshuffling of other planetary bodies that were forming at the time, meaning that the current locations of many planetary bodies in our solar system are not where they originally formed. Lawrence Livermore National Laboratory (LLNL) scientists set out to reconstruct these original formation locations by studying the isotopic compositions of different groups of meteorites that...

New video shows the moment when Mount Etna, Europe's largest active volcano, spewed bubbling lava and hot ash into the Sicilian sky earlier this week.On Sunday (Jan. 17), lava began "oozing" from the Etna's southeast crater and toward the east, according to Boris Behncke, a volcanologist at the INGV-Osservatorio Etneo in Catania, Sicily, Express reported. By Monday evening, the crater exploded in a "new paroxysmal eruptive episode," releasing bursts of lava, hot ash and gas, Behncke tweeted. One lava flow spilled over the east side of the crater, snaking toward the uninhabited Valle del Bove, a horseshoe-shape depression in the...

(Egyptian Antiquities Ministry) ------------------------------------------------------------------------------------------- A funerary temple belonging to Queen Nearit has been discovered in the ancient Egyptian burial ground Saqqara next to the pyramid of her husband, pharaoh Teti, who ruled Egypt from around 2323 BCE to 2291 BCE, the Egyptian antiquities ministry said in a statement. Made of stone, the temple has three mud-brick warehouses on its southeastern side that held offerings made to the queen and her husband. Near the pyramid, the team of Egyptian archaeologists also found a series of burial shafts containing the remains of people who lived during the 18th and 19th dynasties of...

Seeing our world through the eyes of a migratory bird would be a rather spooky experience. Something about their visual system allows them to 'see' our planet's magnetic field, a clever trick of quantum physics, and biochemistry that helps them navigate vast distances. Now, for the first time ever, scientists from the University of Tokyo have directly observed a key reaction hypothesised to be behind birds', and many other creatures', talents for sensing the direction of the planet's poles. Importantly, this is evidence of quantum physics directly affecting a biochemical reaction in a cell – something we've long hypothesised but...

Scientists found that the level of carbon-14, an isotope of carbon, was much higher in rings from that year than usual. Some years later, looking at air samples from ice cores, scientists saw that there were elevated levels of beryllium-10 and chlorine-36 as well. The common factor in all these elements is that they are created when extremely high-energy subatomic particles hit Earth's air and ground. .... The only way to get particles at energies like this is from space, where powerful magnetic fields in exploding stars...can accelerate the particles to such high speeds. But the 774 event was so...

Credit: Jan Skowron / Astronomical Observatory, University of Warsaw ============================================================================= Our Galaxy may be teeming with rogue planets, gravitationally unbound to any star. An international team of scientists, led by Polish astronomers, has announced the discovery of the smallest Earth-sized free-floating planet found to date. Over four thousand extrasolar planets have been discovered to date. Although many of the known exoplanets do not resemble those in our solar system, they have one thing in common — they all orbit a star. However, theories of planet formation and evolution...

Down, down, down. In three minutes, the skip drops nearly 1,700 feet below Cleveland. Then the giant metal door swings open, and you’re deposited in an other-world, with walls, ceiling and floor made of salt. Dirty brown salt at the Cargill mine’s entrance, where the rock has absorbed diesel fumes and dust for more than 60 years. Pristine white, with glimmering flecks, at the mine’s far reaches, 3 miles north, under Lake Erie. “I look out at the water, and it’s like, man, we’re under that!” said Cargill employee Cachet Hilton, 45. Every day, the 5-mile wide mine gets a...

From Jan. 8, 2018 (Bandy's made a career of this) In a bid to have President Donald Trump removed from office, the left is pushing the “diagnosis” of a Yale psychiatrist who has ruled him “unfit” to be president. However, Dr. Bandy X Lee’s own dirty little secret has just been exposed — and it’s bad news for her career. Yale Psychiatrist who 'Diagnosed' Trump Unfit Has Dirty Secret That's Just Been Exposed After giving her professional psychiatric diagnosis of President Donald Trump, rendering him mentally unfit for office, Yale psychiatrist Dr. Bandy X Lee’s prestigious career is in hot...

Several complete skeletons hint at sudden, mass extinctionResearchers from the Whiteside Museum of Natural History in Seymour are unraveling an ancient mystery. "This is life," said Coleton Caldwell, assistant director of the museum. "The first time life is living on land, solely on land, and it's still trying to figure things out, you know? What works, what doesn't work? So it's just really, really, really unique." Working southwest of Wichita Falls, near the shore of Lake Kemp in Baylor County, the researchers have uncovered the skeletal remains of seven dimetrodons. The mammal-like finback reptiles roamed parts of North Texas 60...

A noontime boom that was heard and felt from southern Ontario to Virginia was likely caused by a disintegrating meteor, according to an organization in western New York that keeps track of such phenomena, the AP reports. Witnesses across the area reported hearing the boom or seeing a fireball in the sky shortly after noon on Wednesday, said Robert Lunsford of the American Meteor Society in Geneseo. By 5pm, the organization had recorded 90 reports of the fireball seen in Maryland, Michigan, New York, Ontario, Pennsylvania, and Virginia. Police agencies and fire departments around central New York received 911 calls...

An 8-mile-long "canvas" filled with ice age drawings of mastodons, giant sloths and other extinct beasts has been discovered in the Amazon rainforest. The gorgeous art, drawn with ochre — a red pigment frequently used as paint in the ancient world — spans nearly 8 miles (13 kilometers) of rock on the hills above three rock shelters in the Colombian Amazon, a new study finds. "These really are incredible images, produced by the earliest people to live in western Amazonia," study co-researcher Mark Robinson, an archaeologist at the University of Exeter, who analyzed the rock art alongside Colombian scientists, said...

Artist’s conception of the dust and gas surrounding a new planetary system. Credit: NASA ========================================================================= A long time ago — roughly 4.5 billion years — our sun and solar system formed over the short time span of 200,000 years. That is the conclusion of a group of Lawrence Livermore National Laboratory (LLNL) scientists after looking at isotopes of the element molybdenum found on meteorites. The material that makes up the sun and the rest of the solar system came from the collapse of a large cloud of gas and dust about 4.5 billion years ago. By observing other stellar systems...

Wow. A low-flying space rock set a record last Friday (appropriately, the 13th), when 2020 VT4 passed just under 400 kilometers (250 miles) over the Southern Pacific. The asteroid was spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at the Mauna Loa Observatory in Hawaii in the early morning hours of Saturday, November 14, just 15 hours after approach. This is not uncommon for fast-movers, especially asteroids that are coming at the Earth from our sunward blind-spot, like 2020 VT4. Newly-discovered asteroid A10sHcN approached Earth yesterday, passing only a few hundred miles above the South Pacific Ocean. This...

Italy’s National Institute of Geophysics and Volcanology reported a “high intensity” explosion Monday at the Stromboli volcano, one of the most active volcanoes in the world, located off the southern coast of Sicily in the Mediterranean Sea. The institute’s surveillance cameras captured the event in visual and thermal format early Monday. The explosion could be seen sending ash and steam at least 100 meters into the air and streams of lava rapidly running down the center-south side of the volcano. The institute reported the event lasted four minutes. "From the seismological standpoint," it "was characterized by a sequence of explosive...

NASA, ESA, J. Hester, A. Loll (ASU) ===================================================================== Supernovas may have affected the Earth’s climate in the last 40,000 years. Tree-ring data suggests supernovas caused spikes in radiocarbon. Could the next nearby supernova cause a collapse of civilization? ====================================================================== Dendrochronology is a fancy word for tree-ring dating, where the age of a tree can be determined by the number of growth rings across its trunk. But there’s a lot more to learn from looking at a tree’s rings than simply its age. Like fingerprints, tree rings give scientists clues to what the world was like when a tree was alive....

The remains of a giant, ancient lake have been discovered under Greenland, buried deep below the ice sheet in the northwest of the country and estimated to be hundreds of thousands of years old, if not millions, scientists say. The huge 'fossil lake bed' is a phenomenon the likes of which scientists haven't seen before in this part of the world... Last year, scientists reported the discovery of over 50 subglacial lakes beneath the Greenland Ice Sheet: bodies of thawed liquid water trapped between bedrock and the ice sheet overhead. The new find is of a different nature: an ancient...

The authors present the more than 200 terrestrial impact sites in high-resolution topographic maps and satellite images, complete with detailed geological descriptions and photographs of the crater structures and their rocks. They also explain the essential details of each impact event.

Why is Earth pulsating every 26 seconds, and why canÂ’t scientists explain it after 60 years? This is an enigma wrapped in a periodically predictable mystery motion. It could be a harmonic phenomenon, a regular seismic chirp caused by the sunÂ’s energy, or a beacon drawing scientists to its source to begin a treasure hunt. âž¡ The world is weird. We'll show you how it works. In the early 1960s, a geologist named Jack Oliver first documented the pulse, also known as a "microseism," according to Discover. Oliver, who worked at Columbia University's Lamont-Doherty Geological Observatory at the time, heard...

International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active—erupting for 30 million years—fuelled by a constantly moving conveyor belt of magma. It's believed this magma conveyor belt, created by shifts in the seabed, continuously made space available for the molten rock to flow for millions of years, beginning around 120 million years ago. Research lead Qiang Jiang, a Ph.D. candidate from Curtin's School of Earth and Planetary Sciences, said the studied volcanoes were in the Kerguelen Plateau, located in the Indian Ocean, about 3,000 kilometers...

The South Pole of the Moon. (NASA GSFC Scientific Visualisation Studio) =========================================================================== A distant asteroid trailing in the gravitational wake of Mars has been observed in greater detail than ever before, and the close-up reveals a surprising resemblance – one that raises some interesting questions about the object's ancient origins. The asteroid in question, called (101429) 1998 VF31, is part of a group of trojan asteroids sharing the orbit of Mars. Trojans are celestial bodies that fall into gravitationally balanced regions of space in the vicinity of other planets, located 60 degrees in front of and behind the planet. Most...
