Throughout their history the ancient Egyptians recorded making voyages to a place called the 'Land of Punt'. To the Egyptians it was a far-off source of exotic animals and valuable goods. From there they brought back perfumes, panther skins, electrum, and, yes, live baboons to keep as pets. The voyages started as early as the Old Kingdom, ca. 4,500 years ago, and continued until just after the collapse of the New Kingdom 3,000 years ago. Egyptologists have long argued about the location of Punt. The presence of perfumes suggests that it was located somewhere in Arabia, such as Yemen. However...

It also changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to...

A 2,800-year-old ivory ornament has been discovered by archaeologists in northern Türkiye at the excavation site of Hattusa, the capital of the Hittites, one of the most ancient Anatolian civilizations...In the 117th year of the excavations, a piece of art that can provide insight into Iron Age art was unearthed on the northwest-facing slope of the Great Fortress area of the ancient city.The piece, nearly 30 centimeters (1 foot) in length and 10 cm in width, features a sphinx, a lion, and two trees of life etched on an ivory surface.Speaking to Anadolu, excavation chief Schachner said the artifact was...

Tiny cosmic particles can have serious impacts on Earth, causing election votes to be miscounted, planes to free-fall and computers to reboot, scientists say.These cosmic particles can hit electronic devices on Earth, which can cause components to burn out and cause malfunctions. Cosmic particles come from cosmic rays from outside our solar system. They crash into the Earth's atmosphere creating a range of particles, including protons, electrons, X-rays and gamma-rays that can penetrate aircraft.These cosmic particles constantly hit Earth, and can cause bits of information in electronics to change.

Astronomers have detected one of the most powerful cosmic rays ever observed – and it was beamed at Earth from a mysterious part of deep space.The cosmic phenomenon carried the energy of 240 quintillion electron volts – that’s 240 billion billion (followed by 18 zeros).For comparison, a typical lightning bolt is about 300 million volts.The cosmic ray – named Amaterasu, after the sun goddess in Japanese mythology – was detected by a telescope system in Utah in May 2021 by scientists who described it as ‘unprecedented’ in modern times.

Huge 'sunspot archipelago' 15 times wider than Earth is spotted on the Sun - and scientists warn it could bombard our planet with solar flares capable of causing devastating blackouts Spots on sun described as 'archipelago' as they look like a collection of islands These planet-sized dark spots can release charged particles that hit the Earth By JONATHAN CHADWICK FOR MAILONLINE PUBLISHED: 07:46 EST, 22 November 2023 | UPDATED: 07:46 EST, 22 November 2023 e-mail 34 shares 22 View comments They look like small dots of pepper on a tasty egg yolk, or an 'archipelago' – a big group of...

Gezer is an ancient southern Levantine city, well known from Egyptian, Assyrian, and Biblical texts and associated with stories of power struggles and significant historical figures. It is also a rich archaeological site with abundant Bronze Age and Iron Age remains and with great potential for research into the daily lives of its denizens.Recent excavations at the site have uncovered a continuous stratigraphic sequence that allows for detailed dating and the establishment of an absolute chronology for events at the site.In this study, Webster and colleagues obtained 35 radiocarbon dates on organic materials (mostly seeds) from seven distinct stratigraphic layers...

Though you can’t tell it with the unaided eye from here, the sun is incredibly active. A massive nuclear reaction hurtling through space, sometimes it and its sunspots are more active, meaning they emit more heat and radiation, and sometimes they are less active. Further, it can let fly with plasma, superheated matter, that distorts Earth’s magnetic field and can destroy electronics. That sun activity, called Coronal Mass Ejection (CME), is incredibly dangerous for electronics, many of which are quite fragile and, in the case of infrastructure, expensive and difficult to replace. That’s because the electric charge created by the...

An ancient Egyptian woman had an ovarian tumor with teeth and was buried with a possible healing object.While excavating an ancient Egyptian cemetery, archaeologists made a rare discovery: an ovarian tumor nestled in the pelvis of a woman who died more than three millennia ago. The tumor, a bony mass with two teeth, is the oldest known example of a teratoma, a rare type of tumor that typically occurs in ovaries or testicles.A teratoma can be benign or malignant, according to the Cleveland Clinic, and it is usually made up of various tissues, such as muscle, hair, teeth or bone....

The solar system of the far future is safe from a run-in with a runaway dead star.Last year, researchers looked at the trajectory of a rogue white dwarf star called WD 0810–353 with the Gaia space telescope and predicted that it was due for an encounter with our solar system in around 29,000 years. {snip} While the sun's fate is likely sealed, new research has revealed that our planet at least won't have to worry about being decimated by the chaos caused by runaway white dwarf WD 0810–353 after all. In fact, the "rogue" star won't just miss the solar...

Egyptian archaeologists recently located a lost 3,500-year-old cemetery containing mummies and statues... A particularly exciting find was a Book of the Dead papyrus scroll measuring over 43 feet long—a rare surviving copy of the traditional burial item...While the cemetery—dating to sometime between 1550 BC to 1070 BC—was significant for the hundreds of archaeological finds and tombs carved into the rock located within its boundaries, the discovery of what could be a copy of the Book of the Dead captured the attention of experts as a truly rare find. But with few details released to the public about the contents of...

Sometime in the past year, this tiny planet we live on in an obscure corner of our Milky Way galaxy went through some sort of tipping point, a “state change” of sorts, and now things are different from how they’ve been at any other time in the 300,000 year history of the human race. Nobody knows for sure what that change or tipping point is. — One theory is that variations in dust concentrations in the Northern Hemisphere’s atmosphere — a function of the temperature of the Atlantic Ocean allowing more or less fine dirt to be picked up and...

Scientists believe Kamo’oalewa will remain alongside Earth for millions of years. Could a near-Earth asteroid be a piece of the moon? Astronomers from the University of Arizona believe so. In a captivating cosmic discovery, scientists uncovered evidence suggesting that a near-Earth asteroid called Kamo’oalewa might be a fragment of the moon. The finding challenges previous assumptions about the origins of near-Earth asteroids and could have significant implications for our understanding of celestial bodies close to our planet.

Oct. 26 (UPI) -- An Arkansas family who awoke to the smell of fire discovered a smoking hole in their deck -- and they suspect a meteorite may have been to blame. John Devane of Greenwood said he and his family awoke to the smell of smoke inside their house about 3 a.m. and set about searching for the source. They discovered the smoke was coming from a hole in their deck, which had apparently caught fire. Devane said the flames had been extinguished when a corner of the family's hot tub melted from the heat, causing it to pour...

Oct. 23 (UPI) -- Scientists now believe the moon could actually be around 40 million years older than initially believed, according to new research. The finding comes after a group of researchers reexamined a collection of dust collected from the lunar surface and brought back to Earth in 1972, the last time astronauts visited the moon. Scientists took an in-depth look at crystals embedded within the dust, which was returned to Earth as part of NASA's Apollo 17 mission. Researchers believe a massive collision of debris with Earth led to the creation of the moon. That impact took place around...

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...

Agriculture in Syria started with a bang 12,800 years ago as a fragmented comet slammed into the Earth's atmosphere. The explosion and subsequent environmental changes forced hunter-gatherers in the prehistoric settlement of Abu Hureyra to adopt agricultural practices to boost their chances for survival. That's the assertion made by an international group of scientists in one of four related research papers, all appearing in the journal Science Open: Airbursts and Cratering Impacts. The papers are the latest results in the investigation of the Younger Dryas Impact Hypothesis, the idea that an anomalous cooling of the Earth almost 13 millennia ago...

A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the journal Nature, have important implications...
