Evidence of the most powerful solar storm in history has been uncovered in an unlikely place: within the rings of a tree. This immensely powerful solar storm is thought to have been at least 10 times as powerful as the Carrington Event of 1859, which caused chaos in the rudimentary telegraph system of the time. The researchers found a strange spike in radiocarbon within the rings of subfossilized trees dating to around 14,300 years ago. "Fusa Miyake discovered a sudden and unexpected spike in radiocarbon levels in a Japanese tree from 774 AD. Initially, this was thought to have been...

An ancient tree that contains a record of a reversal of Earth's magnetic field has been discovered in New Zealand. The tree -- an Agathis australis, better known as its MÇori name kauri -- was found in Ngawha, on New Zealand's North Island, during excavation work for the expansion of a geothermal power plant, stuff.nz reports. The tree, which had been buried in 26 feet of soil, measures eight feet in diameter and 65 feet in length. Carbon dating revealed it lived for 1,500 years, between 41,000 and 42,500 years ago... The lifespan of the kauri tree covers a point...

Scientists reveal the potential for massive, and potentially destructive, eruptions from the sun. On May 1, 2019, the star next door erupted. In a matter of seconds, Proxima Centauri, the nearest star to our sun, got thousands of times brighter than usual — up to 14,000 times brighter in the ultraviolet range of the spectrum. The radiation burst was strong enough to split any water molecules that might exist on the temperate, Earth-sized planet orbiting that star; repeated blasts of that magnitude might have stripped the planet of any atmosphere. It would be bad news if the Earth’s sun ever...

Frozen bear mouth The frozen bear came with its teeth well preserved. (NEFU) An adult bear recovered from the Siberian permafrost in the Lyakhovsky Islands in 2020 is not, as originally thought, around 30,000 years old. In fact, its age is more in the region of 3,500 years old. That's the verdict of researchers from the North-Eastern Federal University in Russia, who carried out a new necropsy of the well-preserved specimen. It remains an incredible find, offering an intriguing window into a past that isn't quite as far back as presumed. Initially, the team thought they were dealing with a...

Named Miyake events after the lead author of the first study to describe them, the spikes occur roughly once every 1,000 years or so and are recorded as sudden increases in the radiocarbon levels of ancient tree rings. The leading theory among scientists is that Miyake events are solar flares that are 80 times more powerful than the strongest flare ever recorded. But a new study...suggests that the origin of the radiation bursts could be even more mysterious than first thought. Scientists have spotted six Miyake events in tree rings so far, indicated by sudden, single-year leaps in the concentrations...

Rising as high as 20 feet, ancient stone monoliths in southern Ethiopia are 1,000 years older than scientists previously thought, according to a new study in the Journal of African Archaeology. A Washington State University research team used advanced radiocarbon dating to determine the often phallic-shaped monoliths, or stelae, at the Sakaro Sodo archeological site in Ethiopia’s Gedeo zone were likely created sometime during the first century A.D. The only other attempt to determine the age of the more than 10,000 stele monoliths located at various sites in the Gedeo zone was conducted by French scientists in the 1990s. It...

"It is machination, it is deception," said the director general of the Berlin Royal Museums in his defense when criticized for buying a fake. Wilhelm Bode did not budge an inch: The sculpture he acquired in 1909 was an as-yet unknown production of the great Renaissance master Leonardo da Vinci.After 100 years and numerous controversies, a group of scientists led by a CNRS researcher has just proven him wrong once and for all. The Flora wax bust, conserved at the Bode Museum in Berlin, recently underwent radiocarbon (14C) dating, which provided both a precise date and an incontrovertible result: It...

In 2015, archaeologists discovered a single human cranium (a skull without a lower jaw) in a gypsum cave in Northern Italy called Marcel Loubens cave. Caves are known to have been used for funerary practices in ancient Italy, but the fact that there are no other human remains in this cave has raised questions about how this skull came to be there, inspiring the researchers in this study to conduct a detailed analysis on the bone.The structure of the bone indicates that it belonged to a woman between 24 and 35 years old at death. Carbon dating places the remains...

Using the radiocarbon dating of 27 mud wasp nests, collected from over and under 16 similar paintings, a University of Melbourne collaboration has put the painting at 17,500 and 17,100 years old. “This makes the painting Australia’s oldest known in-situ painting,” said Postdoctoral Researcher Dr Damien Finch who pioneered the exciting new radiocarbon technique. “This is a significant find as through these initial estimates, we can understand something of the world these ancient artists lived in. We can never know what was in the mind of the artist when he/she painted this piece of work more than 600 generations ago,...

Denver Newsroom, Mar 19, 2021 / 03:01 am MT (CNA).- Israeli archaeologists announced this week the discovery of several new sets of Dead Sea Scrolls— ancient fragments of biblical text that have, for the past 70 years, contributed to scholars’ knowledge about the Old Testament. The new scroll fragments, which the Israeli Antiquities Authority announced March 16, include the books of Zechariah and Nahum, both minor prophets. Dr. John Bergsma, professor of theology at Franciscan University of Steubenville who has written and spoken extensively on the Dead Sea Scrolls, told CNA that an interesting feature of the scrolls recently found...

On a day that saw the Israel Antiquities Authority unveil the first Bible scroll fragments found in decades and numerous other dazzling artifacts from the “Cave of Horror” above the Dead Sea — including a huge 10,500-year-old complete woven basket, the oldest in the world — perhaps the most extraordinary news is that there are another 20 promising caves, holding untold potential treasures, that have yet to be excavated. That means the dozens of fragments shown to the public on Tuesday could mark the beginning of an exciting new era of discovery, 60 years after the last major scroll finds....

Dozens of 2,000-year-old fragments from scrolls containing portions of the books of Nahum and Zechariah have been unearthed in Israel, an extremely rare discovery in the Judean Desert. The Israel Antiquities Authority announced the discovery of the uncovered fragments on Tuesday. They are the first of such discoveries in approximately 60 years. The Dead Sea Scrolls are fragments of religious manuscripts that were originally found in the Judaean Desert decades ago. The newly discovered fragments are Greek translations of the two minor prophets. Despite most of the fragments being in Greek, the name of God is written in Hebrew. The...

They also discovered a partially mummified 6,000-year-old skeleton of a child.For the first time in 60 years, archaeologists have discovered a new fragment of the Dead Sea Scrolls, a cache of ancient Jewish and Hebrew religious manuscripts uncovered in the Qumran Caves on the northern shore of the Dead Sea. The Israel Antiquities Authority, which carried out the excavations, believes the new scroll, written in Greek, is actually a missing part of the “Book of the 12 Minor Prophets” scroll, first discovered in 1961. It contains verses from Zechariah 8:16-17 and Nahum 1:5-6. The minor differences in the wording compared...

“These are the things you are to do: Speak the truth to one another, render true and perfect justice in your gates. And do not contrive evil against one another, and do not love perjury, because all those are things that I hate—declares the Lord.” These verses, from Zechariah 8:16–17, were discovered in a cave where Jewish refugees hid almost 1900 years ago. The verses, written on dozens of parchment fragments were discovered in a complex and challenging national-archaeological operation undertaken by the Israel Antiquities Authority on the cliffs of the Judean Desert, since 2017, in order to prevent antiquities...

TEL AVIV - Israeli archeologists on Tuesday revealed dozens of recently-discovered fragments of biblical texts, known as the Dead Sea Scrolls, which build on a collection of ancient Jewish religious manuscripts that was first discovered 60 years ago. Israel’s Antiquities Authorities said that the pieces of parchment feature lines of Greek text from the books of Zechariah and Nahum which have been radiocarbon dated to the 2nd century A.D. The discovery is the result of a years-long Israeli excavation in the Judean Desert and are believed to belong to a set known as “The Cave of Horror,” named for the...

In Rome lies the Santi Apostoli church, cared for by Franciscan brothers for more than 500 years. For more than 1500 years, this site has held the believed remains of two of the earliest Christians and Jesu apostles: St. Philip and St. James the Younger - relics of the Holy Catholic Church... The skeletons are today far from complete. Only fragments of a tibia, a femur and a mummified foot remain. The tibia and foot are attributed to St. Philip, the femur to St. James. It appears likely that this has been the case since the sixth century... The researchers...

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...

A DEVASTATING burst of gamma-rays may have caused one of Earth's worst mass extinctions, 443 million years ago. A team of astrophysicists and palaeontologists says the pattern of trilobite extinctions at that time resembles the expected effects of a nearby gamma-ray burst (GRB). Although other experts have greeted the idea with some scepticism, most agree that it deserves further investigation. GRBs are the most powerful explosions known. As giant stars collapse into black holes at the end of their lives, they fire incredibly intense pulses of gamma rays from their poles that can be detected even from across the universe...

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....
