A massive, semi-continent-sized subsurface structure has been discovered by scientists beneath Antarctica’s frozen surface. The discovery, reported by an international team of scientists, reveals the presence of an unusually shaped feature which researchers with Durham University’s Department of Geography characterize as a “vast geological structure hidden beneath the East Antarctic Ice Sheet.” The discovery was recently detailed in a study featured in Nature Geoscience. A Massive Fan-Shaped Structure Composed of several gigantic basins located beneath more than three kilometers of the southern continent’s icy exterior, the unusual structure has been dubbed the “East Antarctic Fan-shaped Basin Province.” The massive feature...

A slice of NWA 12774.The green circle is an olivine crystal, a magnesium-rich mineral. (Credit: John Kashuba) In A Nutshell A meteorite recovered from the Sahara contains crystals that could only have formed deep inside a large, now-destroyed ancient planet, giving scientists their first direct physical evidence of its enormous size. Using a newly developed pressure-measuring tool, researchers calculated the parent body was at least 1,000 kilometers in radius, far larger than any asteroid previously linked to this class of meteorite. Textural clues in the crystals suggest the planet may have been Moon-sized or even larger, though that conclusion depends...

The Sun runs on an 11-year cycle of rising and falling activity, tracked mainly by counting sunspots – the dark patches scattered across its surface. Solar Cycle 25, the current cycle, was forecast as mild, and the sunspot count agreed. But those counts read only the surface. A global network of six telescopes has listened to the Sun’s interior for nearly 40 years, and what it is now telling researchers is not what the surface suggested at all. Listening inside the Sun Scientists have a name for eavesdropping on those sound waves: helioseismology. The waves are trapped inside the Sun,...

The Battle of Qarqar, fought in 853 BCE, stands as a landmark event in the annals of military history, notable for featuring the earliest documented military alliance among a coalition of twelve kingdoms. This confederation was assembled to counter the expansive ambitions of the Assyrian Empire under King Shalmaneser III. The battle, although not decisively conclusive in its military outcomes, offers profound insights into the geopolitical dynamics of the ancient Near East and the complexities of coalition warfare. Background and Strategic Context During the early 9th century BCE, the Assyrian Empire, led by Shalmaneser III, was in a phase of...

A hefty, never-before-seen asteroid is racing toward Earth at around 20,000 mph (32,000 km/h) and will zoom past our planet closer than some satellites on Monday (May 18), scientists say. You can watch the unusually close encounter for yourself, even if you don't have access to stargazing equipment. The asteroid, dubbed 2026 JH2, was discovered May 10 by astronomers at the Mount Lemmon Observatory near Tucson, Arizona, who also spotted the superbright Comet Lemmon last year. The space rock, which has since been verified by other observatories across the globe, likely circles the sun every 3.7 years on an elliptical...

Just as it faces an annual hurricane season and tornado season, North America is also experiencing an annual "fireball season," according to NASA."From February through April, the appearance rate of these very bright meteors can increase by as much as 10 percent to 30 percent, especially around the weeks of the March equinox," NASA explained in a statement in late March. "Exactly why is not known. Some astronomers think the Earth passes through more large debris at this time of year, causing an uptick in fireball sightings."...The American Meteor Society, which has gathered professional and amateur meteor reports since 1911,...

Beneath a section of Chicago, there is a hidden several mile wide impact crater. This might initially seem like a crazy claim but it is true, existing underneath the city of Des Plaines. The only reason it isn't highly visible today is due to sediments emplaced during extensive glaciers during the last 2 million years. It is for this reason that I will discuss when this crater formed, what evidence we have, and what immediate effects its formation had. Thumbnail Photo Credit: Google Earth.

The history of the Trojan horse is probably one of the most famous stories ever told. A gigantic wooden horse is loaded with Greek soldiers and presented to the Trojans as a gift. Unsuspecting, they swallow the bait and pull the horse into the city. Under cover of darkness the Greeks slip out of the horse and open the gates to their comrades. Only hours later the mighty Troy goes up in flames. But what if the myth of the horse is not true at all? New, groundbreaking findings show that one of the most famous stories of all time...

Archaeologists in Egypt recently uncovered a massive statue believed to depict King Ramses II, the pharoah believed to be a major character in the Old Testament. The statue was found at the Tel Pharaoh site in Husseiniya Center, Sharqia Governorate, the Egyptian Ministry of Tourism and Antiquities said on April 22. The site is in Egypt's Nile Delta, northeast of Cairo. Officials also described the statue as "remarkable" in size, weighing between 5 and 6 tons and measuring over 7 feet long. In a translated statement, the ministry described the statue as being in a "relatively poor condition of preservation,"...

In the ancient Mitanni Kingdom, an Indo-Aryan language very closely related to Sanskrit was used by the ruling class -- but only for very special occasions... Jack of All Languages explores the surprising linguistic links between ancient Indo-Aryan terms found in Syrian horse training manuals and early Sanskrit. By analyzing archaeological tablets and royal treaties, this investigation sheds light on how a prestige language influenced elite cultures in the Middle East centuries before the oldest known Vedic texts were composed.

Long ago in a land now lost to the sea, and event happened that changed how those that lived there, saw their landscape forever. This is Doggerland, the land bridge that once connected Britain with mainland Europe. It would take an eventual slow and long sea rise to remove this world, but.. something else happened. Something that changed the landscape in one instant. More devasting than we ever could image. Paul Whitewick examines how the 6,200 BC Storegga Slide tsunami dramatically altered the landscape of Doggerland. By analyzing geological cores and ancient artifacts, they explore how this catastrophic event fundamentally...

A new study of southern Norway's Raknehaugen mound conducted by Lars Gustavsen of the Norwegian Institute for Cultural Heritage Research suggests that it does not contain a burial and may have been built in response to a landslide, according to a Phys.org report. "I actually discovered the landslide scar more or less by accident," Gustavsen said. "While investigating the visibility of the mound using LiDAR data, it suddenly appeared in one of the visualizations I was using to analyze the landscape," he said. When the mound was excavated in 1869 and 1870, no central burial mound was found. Excavations in...

Near-Earth asteroid Apophis is a potentially hazardous asteroid that will safely pass close to Earth on April 13, 2029. It will come about 20,000 miles (32,000 kilometers) from our planet’s surface — closer than the distance of many satellites in geosynchronous orbit (about 22,236 miles, or 36,000 kilometers, in altitude).

AbstractThe Homeric epics are among the greatest masterpieces of literature, but when they were produced is not known with certainty. Here we apply evolutionary-linguistic phylogenetic statistical methods to differences in Homeric, Modern Greek and ancient Hittite vocabulary items to estimate a date of approximately 710-760 BCE for these great works. Our analysis compared a common set of vocabulary items among the three pairs of languages, recording for each item whether the words in the two languages were cognate - derived from a shared ancestral word - or not. We then used a likelihood-based Markov chain Monte Carlo procedure to estimate...
