The region surrounding Sagittarius A*, the Milky Way’s own supermassive black hole. Eventually, black holes will be the last remaining matter in the universe. The cosmos may never end. But if you were immortal, you’d probably wish it would. Our cosmos’ final fate is a long and frigid affair that astronomers call the Big Freeze, or Big Chill. It’s a fitting description for the day when all heat and energy is evenly spread over incomprehensibly vast distances. At this point, the universe’s final temperature will hover just above absolute zero. The Big Bang’s accelerating expansion Some 13.8 billion years ago, our universe was…

HARPY EAGLE (HARPIA HARPYJA) Harpy eagles can be found in the tropical…

The Aztecs ritually sacrificed people to appease their gods. They displayed the heads of their dead on enormous, cylindrical racks called tzompantli, constructed using rows of skulls mortared together. The Aztecs used these towers to show off their empire’s might to enemies and invaders. Last week, Mexico’s National Institute of Anthropology and History (INAH) announced that researchers had discovered a section of one such tower under the ruins of Mexico City’s Templo Mayor. It contained 119 skulls from men, women, and children. Archaeologists first discovered this tower, called Huei Tzompantli, five years ago. The skulls date back more than 500 years.…

Thonis  Heracleion the Lost City: In 1987 maritime archeologist Franck Goddio founded the Institut Européen d’Archéologie Sous-Marine (The European Institute of Underwater Archaeology) in order to concentrate solely on underwater excavations. He has found several important shipwrecks including the San Diego found in the waters of the Philippines and Napoleon Bonaparte’s flagship during his campaign in Egypt, the Orient. His most important excavation to date is the discovery of the ancient sunken port city of Thonis Heracleion and parts of the city of Canopus in the Bay of Aboukir near Alexandria, Egypt. Partnered with the Egyptian Ministry for Antiquities, Goddio and his team…

The film was inspired by a real-life event, namely an attack by sooty shearwaters on Capitola,…

Archaeologists have discovered an ancient Egyptian temple with 15 mummified falcons, many of them headless and buried around a pedestal. The discovery suggests a previously unknown ritual performed by the Blemmyes, a nomadic people who once inhabited what is now southern Egypt and Sudan. The team of Spanish and Polish archaeologists just published an extensive analysis of their findings during the 2019 excavation season at Berenike, an ancient and long-abandoned Red Sea port city that borders Egypt’s Eastern desert. These intriguing results, which appear in the American Journal of Archaeology , provide detailed information about the religious shrine or temple…

(Inside Science) — Experts believe the building blocks of life first bumped into each other about 3.5 billion years ago. This serendipitous collision somehow helped form the first rudimentary cell — and the first life on Earth. At least, that’s been the predominant theory. Now, a team of scientists from the University of Washington is challenging this idea in a paper published in the journal Proceedings of the National Academy of Sciences. They propose that membranes might have been the key component that helped congregate the pieces needed to create the first cell. “If you want to explain life, you have to explain…

The “Oldest Gold Of Mankind” was found in the Varna Necropolis, on The Bulgarian Black Sea Coast In 1972, an excavator operator working in the industrial zone of the city Varna will stumble upon something that will turn out to be a very significant historical site. The Varna Necropolis has discovered approximately half a kilometer from Lake Varna and 4 km from the city center. It is estimated that it was made sometime between 4,600 BC to 4,200 BC. Around 300 graves have been found at this burial site, but the most significant is grave 43. It contained the remains…

The charges related to the reckless use of illegal poison resulted in the deaths of 15 birds, including five red kites. A PENSIONER has been convicted of killing raptors and other wild birds with poison, executing 15 in total. Barry Nicolle, 67, admitted numerous charges at Dumfries Sheriff Court on Wednesday. He is due to be sentenced on Friday, May 19. The charges related to the reckless use of illegal poison resulted in the deaths of 15 birds, including five red kites, in the Stewarty area of Dumfries and Galloway between 2019 and 2020.

Earth’s magnetic field is incredibly important to life on our planet. Beyond allowing for compass navigation and displaying the Aurora Borealis way up north, it is responsible for shielding us from the worst effects of the Sun’s rays. A little bit of Sun, we need—a lot would have some serious negative impacts. Thankfully, we do have a magnetic field. But there’s a bit of a problem: Our magnetic field has a dent in it—what ScienceAlert calls a “pothole in space.” It’s called the South Atlantic Anomaly (SAA), and it’s not a physical dent. It’s a region in the skies between…

The newly-discovered dormant black hole, named Gaia BH2, is orbited by a red giant star, and has a mass of 8.9 solar masses. Gaia BH2 is located approximately 3,800 light-years away in the constellation of Centaurus. This black hole, as well as Gaia BH1, was discovered by studying the movement of its companion star. A strange ‘wobble’ in the movement of the stars on the sky indicated that they are orbiting a very massive object. Other explanations for these massive companions, like double-star systems, were ruled out since they do not seem to emit any light. The distance of the stars…

Hoard of Viking coins worth at least £500,000 found during police raids A hoard of Viking coins has been confiscated by police investigating an illegal trade in historic treasures that could rewrite British history. The collection of coins and a silver ingot, dating back to King Alfred the Great’s reign of the 9th century, were retrieved at households in Durham County and Lancashire by police. Believed to be worth at least £500,000, a leading expert has told the MailOnline they could ‘add significantly to our understanding of the political history of England in the AD 870s’ as they reveal a…

Archaeologists Say New Airport Near Machu Picchu “Would Destroy It” The Incan citadel of Machu Picchu in Peru is one of the world’s most stunning pieces of engineering, and a hypnotizing, historical remnant of a mystical past. Nestled in the Andes at around 8,000 feet, the government is now planning to boost the lucrative tourism it draws annually even more — by building a multibillion-dollar international airport nearby, which critics are adamant “would destroy it.” The Unesco World Heritage Site is traditionally reached by taking a flight to the Cusco airport 46 miles away, which only has one runway. From…

The origin of life is one the great unanswered questions in science. One piece of this puzzle is that life started on Earth 4.5 billion years ago, just a few hundred million years after the formation of the Solar System, and involved numerous critical molecular components. How did all these components come to be available so quickly? One potential explanation is that the Earth was seeded from space with the building blocks for life. The idea is that space is filled with clouds of gas and dust that contain all the organic molecules necessary for life. Indeed, astronomers have observed…

When you stack up the most promising recent exoplanet finds, as illustrated here, it becomes clear none is Earth’s true twin. But even more habitable worlds may be out there waiting to be found. Earth is the only place in the universe where we know life exists. But with billions of other star systems out there, it might not be the best place for life. In a new study, astronomers modeled the potential for life on other watery planets and found some conditions that can create oceans maximized for habitability. The model suggests that watery planets with dense atmospheres, continents, and…

Siberian Princess reveals her 2,500-year-old tattoos The intricate patterns of 2,500-year-old tattoos – some from the body of a Siberian ‘princess’ preserved in the permafrost – have been revealed in Russia. The remarkable body art includes mythological creatures and experts say the elaborate drawings were a sign of age and status for the ancient nomadic Pazyryk people, described in the 5th century BC by the Greek historian Herodotus. But scientist Natalia Polosmak – who discovered the remains of ice-clad ‘Princess Ukok’ high in the Altai Mountains – is also struck about how little has changed in more than two millennia.…

The new image is not only cute, it also illustrates a psychological phenomenon known as pareidolia. The University of Arizona’s Lunar and Planetary Laboratory recently shared this image of several martian surface features that combine to resemble the face of a bear. NASA’s Mars Reconnaissance Orbiter recently snapped an unexpected — and adorable — image of a martian formation that bears a striking resemblance to the face of a woodland creature more commonly found on Earth: a bear. The new image was captured Dec. 12 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO), a spacecraft…

Think telling sparrows apart is just not worth the effort? Our tips might change your mind. Identify sparrows by habitat, range, season, field marks and more! It’s easy to lump all sparrow bird types together: “Yep, looks like a sparrow to me.” You can find at least 33 species of native sparrows across the country. And while their plumage won’t sweep you off your feet the way an oriole or a bluebird will, they’re still worth your time and attention. Fall and winter bird feeding just wouldn’t be the same without these little brown birds. They liven up the feeder scene as they hop about, pecking in the…

Mars’ Jezero Crater was once home to a river delta. That history, and the potential for finding signs of ancient alien life, pushed NASA to pick Jezero as the landing site for its Perseverance rover. Billions of years ago, an enormous space rock struck Mars and excavated a 750-mile-wide (1,200 kilometers) crater now called the Isidis impact basin. But the cosmos wasn’t done yet. Another smaller strike inside the basin later produced an embedded crater that’s since been dubbed Jezero Crater. The overlapping pair of impacts uniquely changed the rocks in the region, helping to create a special landscape that…
