Archeologists offered a first image of the site where 80 skeletons in a mᴀss grave with wrists clamped by iron shackles lie in an ancient Greek cemetery. The skeletal remains show the bodies were placed in a row upon death. The archaeologists team said that the fossils, which could dated from 632BC, were the result of a mᴀss execution. But how they got there, who they were and why they appear have been buried with a measure of respect is still a mystery. They were located in the Falyron Delta necropolis , a large ancient cemetery that was uncovered in the…

Mysteries of the Oort cloud at the edge of our solar system The entirely theoretical cloud of icy space debris marks the frontiers of our solar system. The Oort cloud represents the very edges of our solar system. The thinly dispersed collection of icy material starts roughly 200 times farther away from the sun than Pluto and stretches halfway to our sun’s nearest starry neighbor, Alpha Centauri. We know so little about it that its very existence is theoretical — the material that makes up this cloud has never been glimpsed by even our most powerful telescopes, except when some…

Ice holds evidence of ancient, massive solar storm An analysis of radioactive chemicals in ice cores indicates one of the most powerful solar storms ever hit Earth around 7176 B.C. (Inside Science) — For a few nights more than 9,000 years ago, at a time when many of our ancestors were wearing animal skins, the northern skies would have been bright with flickering lights. Telltale chemical isotopes in ancient ice cores suggest one of the most massive solar storms ever took place around 7176 B.C., and it would have been noticed. “We know that most high-energy events are accompanied…

King Tutankhamun’s outer coffin is being restored for the Grand Egyptian Museum’s opening in late 2020. The pharaoh’s tomb was restored earlier this year. From the time that King Tutankhamun’s body was placed, the outermost sarcophagus had never left the 3300-year-old tomb. Even in 1922, following the discovery of the tomb by the British archeologist Howard Carter, the outer coffin made from wood and gold stayed in the Valley of Kings — until now. An almost 10-year redevelopment of Tut’s tomb was completed in earlier this year by the Getty Conservation Institute and the Egyptian Ministry of Antiquities. Now, The…

These free-range planets rove around in a pairIt’s basically a solar system without a sun. The strange, free-floating 2MASS J11193254–1137466 is actually 2MASS J11193254–1137466AB, a binary system of rogue planets ejected from a star in the TW Hydrae association.Gemini Observatory/Jon Lomberg IllustrationA rogue planet long escaped from its home stellar system may not be so alone on its trip.2MASS J11193254–1137466 was announced last year as an untethered planetary-mass system in the TW Hydrae association, a grouping of stars with a center point about 95 light-years away. 1137466 is around 160 light-years away, but its motion indicates an 80 percent possibility…

The beak is, arguably, the most important and distinctive aspect of a bird. It’s necessary for eating, preening, defense, and even mating displays, and plays a large role in how the bird interacts with their environment. Beaks come in all shapes and sizes. Some birds have short beaks, some have long. Other birds have tiny beaks, while some like you’ll soon see, have quite large beaks. In this article we’re going to look at some examples of birds with big beaks. Birds with big bills have evolved throughout the world for a long time, carving out niche roles in their…

Falcons may look like little hawks, but they are in a category of their own. There are about 40 species worldwide that belong to the genus Falco.  Known for their keen eyesight, hunting prowess, and fast speeds, they make up a small portion of the “birds of prey” category. In this article, we are going to look at the 7 types of falcons you can find in the United States. TYPES OF FALCONS IN THE UNITED STATES There are 7 species of falcon that currently make the U.S. their home, at least for part of the year. This is excluding the…

The Katskhi Pillar – the Most Incredible Cliff Church in the World It is not unusual to listen to tales of people who have lived a solemn life away from the world, whenever these stories are reported, people are fascinated and awestruck. This idea is far from our normal life to most of us. This was the case when the news broke out of a monk alone living on a giant rock in Georgia. Katskhi, the small town of the Katshkipillar – an enormous natural limestone column that rises 130 feet into the air – is located in the west-georgian area…

What would Earth look like to alien astronomers?A new paper asks which exoplanets could find Earth. Such worlds could be targets for SETI searches. Ever since 1992, when astronomers first discovered two rocky planets orbiting a pulsar in the constellation Virgo, humans have known that other worlds exist beyond our solar system. Today, thanks to the efforts of astronomers and ambitious missions like the now-retired Kepler, we know of more than 4,000 confirmed exoplanets. But if we can see exoplanets orbiting distant stars, that means extraterrestrial observers should be able to see Earth orbiting the Sun. Our tiny blue marble even could be…

Astronomers believe that planets, asteroids, and other solar system bodies form from the disk of dust and debris around a young star. But what happens before that?NASA/JPL-CaltechAstronomers know that our solar system formed about 5 billion years ago from material left over from previous generations of stars. However, beyond that, it gets a little murky.The prevailing theory is that a nearby supernova explosion compressed a dense cloud of gas and dust until it collapsed in on itself due to its own gravity. As the cloud condensed, it grew hotter and spun faster. Eventually, the center of the cloud grew so…

In this article I compiled a list of some of the most colorful birds in north America. There are so many different colorful birds in the United States alone, that I found this article getting bigger and bigger until finally I realized I had to stop somewhere. So while I may not have every colorful bird listed here, I have quite an extensive list. Feel free to suggest any you think belong on this list in the comments. Some of the birds are common and recognizable, others aren’t. Not all will eat at feeders and not all are birds that you will…

Underwater archaeologists searching just off the western Mediterranean coast of the city of Pozzuoli in central Italy discovered the remains of a submerged 2,000-year-old Nabatean temple dedicated to their god Dushara. What they found specifically were two Roman marble altars, which linked the temple to the period when Nabataeans were living freely on the Phlegrean Peninsula 125 miles (200 km) south of Italy’s capital city, in territory fully controlled by the Roman Empire. The Nabataeans were an Arab tribal group who lived as wandering nomads in the deserts of the Arabian Peninsula in the first few centuries of the first millennium. But…

Everybody has a different memory of what they did during the long days of pandemic lockdown. While some of us struggled to stay afloat among work and childcare, others — like graduate student Rebecca Hahn (Washington University in St. Louis) found the quiet time they needed for time-consuming endeavors. Hahn took the highest-resolution imagery available of the Venusian surface — that gathered by NASA’s Magellan spacecraft 30 years ago — loaded it into mapping software like that used by engineers and urban planners on Earth. Then she set out to map every single volcano visible in the grainy, black-and-white images…

BIRDS THAT START WITH J Below is a list of 16 interesting and varied bird species whose name starts with J. Let’s take a look! 1. JACKY WINTER Scientific name: Microeca fascinansLives in: Australia, Papua New Guinea You will hear these birds from early in the morning up to midday singing their “peter-peter” song.  Jacky winter’s are small grey-brown flycatchers. There are three subspecies with slight color variations, being generally darker in the south and paler in the north. The Jacky winter is an insectivore, which means that it mainly feeds on insects. It is known as a sit-and-search predator, flying out from…

The Ancient Underwater 5,000- Year-Old Sunken City in Greece is considered to be the Oldest Submerged Lost City in the World. Pavlopetri is about 5 000 years old and one of the oldest populated city (oldest in Mediterranean sea). It is situated on the southern shore of Laconia, in Peloponnese, Greece. The name Pavlopetri (“Paul’s and Peter’s”, or “Paul’s stone”) is the modern name for the islet and beach, apparently named for the two Christian saints that are celebrated together; the ancient name or names are unknown. Discovered in 1967 by Nicholas Flemming and mapped in 1968 by a team…

Scientists may have found one of the oldest Christian churches in the world Scientists may have found one of the most ancient Christian churches in the world by using muon x-rays to scan a mystical subterranean building on the coast of the Caspian Sea in the ancient Russian city of Derbent. Now, thanks to the clever use of scanning technology, we might finally know what the building is. The fortress of Naryn-Kala in Derbent, Russia, dates back to around A.D. 300 The technology known as the muon X-ray is used by researchers to track the charged subatomic particles muons, generated when…

Did the solar system form in a bubble?Researchers have laid out a new, comprehensive theory for how the solar system formed — inside the bubble of a long-dead, giant star.

Mysterious Secret Tunnel Discovered Under Ancient Pyramid in Mexico As we use advanced archeological techniques, we appear to create incredible findings at various ancient locations, like Teotihuacan in Mexico. Recently, in Teotihuacán’s ancient town northeast of Mexico City, archeologists have discovered a secret tunnel under the famous Moon Pyramid. Hidden for ages, the underground tunnel, as archeologists claim, could represent the underworld as a component of the ancient system of belief in the Pre-Colombian civilization that once thrived here. The Moon Pyramid is the second largest structure seen in Teotihuacán. The site was most certainly built 2,000 years ago, by a…

Astronomers have used the James Webb Space Telescope (JWST) to reveal a host of high-mass galaxies in the early universe — but according to a new study they shouldn’t really exist. Either astronomers have misunderstood something about the galaxies themselves, or our leading model of cosmology is called into question. Despite being in space less than 18 months, JWST is already providing unprecedented views of the universe in the first few hundred million years after the Big Bang. A big surprise has been how quickly large, star-filled galaxies appeared. Now, Michael Boylan-Kolchin (The University of Texas, Austin) has looked at…
