Well-Preserved Maya Canoe Found in Mexico May Be 1,000 Years Old. 10 Earth impact craters you must see. Planet Earth holds some of the strangest, natural tourist destinations in the solar system.
Earth is perpetually bombarded with debris from outer space. Luckily for us, most of it burns up during entry through our atmosphere and we enjoy this bright burn in the night sky in the form of fleeting meteor showers. But on occasion, an object is so big it survives its entry through the atmosphere and it leaves its mark on the planet, literally. According to the Lunar and Planetary Institute, impact craters are formed when a planet's surface is struck by a meteoroid, leading to the excavation of the surface material. These impact structures are characteristically roughly circular, excavated holes. According to the Planetary and Space Science Centre (PASSC) at the University of New Brunswick in Canada, there are 190 confirmed impact structures on Earth.

The discovery was made in data from comet 67P/Churyumov-Gerasimenko by the Rosetta probe a few years ago, strengthening the idea that life’s ingredients were delivered to Earth by comets. Six chemical elements make up almost all biological molecules on Earth: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur (CHNOPS). How our home planet managed to become so bountiful in all of them has long been a mystery, but one of the leading hypotheses is that they were brought here long ago by comets, asteroids, and impacts with proto-planets.

Ancient Persian culture exerted a powerful influence throughout the Near East, and beyond, for over a thousand years between c. 550 BCE - 651 CE and many aspects of their culture continued to influence others afterwards and up through the present day.
Stunning leopard face reconstructed from ancient Egyptian sarcophagus. Archaeologists released a gorgeous image showing a digital reconstruction of a colorful leopard's face that once adorned an ancient Egyptian sarcophagus.
The leopard's head would have aligned with mummy's head inside the sarcophagus, researchers from the University of Milan explained in a statement. That position was likely chosen to offer the deceased the strength necessary to complete their overseas journey and to regenerate. "We made the discovery at the end of January 2019, but just finished the 'virtual' restoration of the fragment," Patrizia Piacentini, director of the excavation for the Egyptian-Italian Mission at West Aswan, told Live Science. Archaeologists were able to digitally reconstruct a leopard image from pieces of a sarcophagus cover. (University of Milan) The animal itself represented power and determination in ancient Egypt, according to the researchers.

Earth Could Have Once Been a Waterworld Covered by a Global Ocean, Study Suggests. When it was very young, the planet Earth looked rather different from the one we know and love today.
For one, it had supercontinents - when the landmasses we currently live on were arranged in various configurations as they were pushed around by tectonic movements. But there may have been a period when there were very few or no landmasses at all, and Earth was a soggy waterworld, according to new research. Evidence found in the geologic record suggests that, around 3.2 billion years ago, our currently 4.5-billion-year-old homeworld was covered by a global ocean.
If confirmed, such a finding could help to resolve questions around how life emerged roughly 3.5 billion years ago; in particular, whether it got its start in freshwater ponds on landmasses, or in salty seas. ‘Astounding new finds’ suggest ancient empire may be hiding in plain sight. SAN JUAN TEOTIHUACAN, MEXICO—On 16 January 378 C.E., a stranger arrived in Tikal, a large Maya city in what is now northern Guatemala.
His name was Sihyaj K’ahk’ (SEE-yah Kak), or Fire is Born, and he was likely a mighty warrior from a distant land. Many archaeologists think he hailed from Teotihuacan, a metropolis of 100,000 people about 1000 kilometers northwest of Tikal, near today’s Mexico City. And he may have come with an army. Ancient 'outlaw temple' discovered in Israel. The discovery of an Iron Age temple near Jerusalem has upended the idea that the ancient Kingdom of Judah, located in what is now southern Israel, had just one temple: the First Temple, also known as Solomon's Temple, a holy place of worship in Jerusalem that stood from the 10th century B.C. until its destruction, in 586 B.C.
The newfound temple — whose roughly 150 congregants worshiped Yahweh but also used idols to communicate with the divine — was in use during the same period as the First Temple. Its discovery shows that, despite what the Jewish Bible says, there were other contemporary temples besides the First Temple in the kingdom. "If a group of people living so close to Jerusalem had their own temple, maybe the rule of the Jerusalem elite was not so strong and the kingdom was not so well established as described in the Bible?

How one Paleontologist is Changing That. Your local natural history museum probably displays its most impressive fossils front and center, ready to awe visitors.
But some museums also house troves of other remains, filed away in drawers, that could reveal helpful details about their eras of origin. Usually, there’s no scientific literature describing these fossils, and only museum workers have access to them. Researchers call these unstudied items “dark data.” Native American lost city of Cahokia: Experts debunk myth surrounding its demise.
A team of archaeologists is debunking the myth surrounding the demise of the lost Native American civilization that was once at Cahokia Mounds near Collinsville, Ill.
Experts analyzed ancient human feces to shed new light on the lost city, challenging the narrative about its legendary end. “In its heyday in the 1100s, Cahokia — located in what is now southern Illinois — was the center for Mississippian culture and home to tens of thousands of Native Americans who farmed, fished, traded and built giant ritual mounds,” explained the University of California, Berkeley, in a statement. “By the 1400s, Cahokia had been abandoned due to floods, droughts, resource scarcity and other drivers of depopulation.” The pre-Columbian Mississippian culture lasted from approximately 700 A.D. until the arrival of Europeans, according to Encyclopaedia Britannica.

History. Geography. Warfare. Diplomacy. Scientists have discovered deepest point on land. A new study shows that the deepest point on land is under the Denman Glacier in East Antarctica.
Glaciologists at the University of California, Irvine, were mapping the area only to find that the trough under the glacier went far deeper than they had imagined. The trough is about 3.5 km (about 2 miles) below sea level but there is no ocean water there. Instead, it is filled with ice flowing from the interior of the ice sheet towards the coast. The trough measures about 100 km in length and is 20 km wide, according to the study. This new discovery was presented at the American Geophysical Union’s Fall Meeting in San Francisco. Dr. “The biggest challenge about the project is that Antarctica is HUGE!”
Morlighem and his team used a new technology called BedMachine to make this discovery. “After months of investigation, we realized that it was not because we were missing important processes.
