    It's no surprise that water was crucial to the formation of life on Earth. What may surprise you is that water on earth is older than the sun itself. Identifying the original source of Earth's water is key to understanding how life-fostering environments came into being and how likely they are to be found elsewhere. A new paper in Science says that much of our Solar System's water likely originated as ices that formed in interstellar space. Water is found throughout the Solar System, not just on Earth; on icy comets and moons, and in the shadowed basins of...

    More than 3,300 years ago, in a newly built city in Egypt, a woman with an incredibly elaborate hairstyle of lengthy hair extensions was laid to rest. She was not mummified, her body simply being wrapped in a mat. When archaeologists uncovered her remains they found she wore "a very complex coiffure with approximately 70 extensions fastened in different layers and heights on the head," writes Jolanda Bos, an archaeologist working on the Amarna Project, in an article recently published in the Journal of Egyptian Archaeology. Researchers don't know her name, age or occupation, but she is one of hundreds...

    Underwater excavations led by Ankara UniversityÂ’s Research Center for Maritime Archaeology (ANKĂśSAM) have uncovered sunken ships ranging from the second century B.C. to the Ottoman period in Ä°zmirÂ’s Urla district. A recent excavation uncovered a ship estimated to date back 4,000 years, which experts say would make it the oldest sunken ship to have been discovered in the Mediterranean. Urla Port is one of TurkeyÂ’s rare underwater excavation sites. Professor Hayat Erkanal, the head of Limantepe excavations for the underwater ancient city of Klozemenai and director of ANKĂśSAM, said the port dates back to the seventh century B.C.

    Researchers at Caltech and the University of Miami in Florida found that the volcano pictures, such as those that are forming the Hawaiian Islands, illustrate that it erupts when magma gushes out as narrow jets from deep inside Earth but those pictures are wrong. Don Anderson, the Eleanor and John R. McMillian Professor of Geophysics, Emeritus, at Caltech said that new seismology data are now confirming that such narrow jets don't actually exist. He further explained that, in fact, basic physics doesn't support the presence of these jets, called mantle plumes, and the new results corroborated those fundamental ideas. It...

    Recently, rumors have been swelling of a danger at Yellowstone National Park. That danger? A brewing supervolcano eruption. The fear of a Yellowstone supereruption, which ultimately went viral, may have begun back in February when a seismometer called B944 began sending senseless data to a public viewer at the University of Utah's seismographic station, as George Black reports in The New Yorker. Luckily for most of the U.S., the likelihood this eruption would happen is pretty low: about one in 100,000 any given year. If it did happen, it would be pretty devastating, though.

    Ajai RajSeptember 8, 2014 Last Friday's eruption at Iceland's Bardarbunga volcano had many worried about the possible impacts of a larger eruption on air travel. Another eruption at Hawaii's Kilauea volcano has caused a state of emergency to be declared on Big Island, as lava flows from the ongoing eruption have advanced within a mile of a residential zone. That's just one example of how much danger volcanoes pose to the U.S. — and we aren't doing much about it. Compared with Iceland, the U.S. is much more vulnerable to volcanic disasters — and has been failing at monitoring these...

    On Sunday afternoon — at 2:15 pm Eastern time, to be exact — a small asteroid will whiz by the Earth. Don't worry: it'll miss us by about 25,000 miles. To be clear, there is zero chance it can hit us. This is certain. But in the long-term, worrying a little about asteroids isn't an unreasonable idea. Now, the odds of a massively destructive asteroid impact at any given time are tiny — but the potential costs would be enormous. Yet we still haven't invested in all the infrastructure needed to spot small asteroids with much warning (we spotted this...

    Dr Kurt Retherford of the Southwest Research Institute in San Antonio told Space.com that he thought this was unlikely. ‘The best explanation still is plumes for that [December 2013] dataset, no doubt about it,’ he said. Another suggestion is that the plumes may be too small to see; indeed, even Cassini has struggled to spot vapour associated with the plumes being expelled into space. The previous evidence for the jets had come in the form of water vapour spotted by Hubble above Europa. Although several explanations were offered, Nasa was pretty sure this vapour was due to erupting plumes on...

    Just how massive is that water loss? In a paper published this week in Science, the team estimates the deficit at nearly 240 gigatons, or 63 trillion gallons of water. That much water spread across the entire western United States would run four inches deep. If there's one piece of good news here, it's that the uplift of the tectonic plates in the drought zone shouldn't change the likelihood of earthquakes or other seismic events. "This will change the stress on faults, but by an amount that's really small," Agnew told Popular Science. That's probably small solace to the people...

    Iceland raised its aviation alert to red Saturday as a subglacial eruption began at the restless Bardarbunga volcano, which has been rattled by thousands of earthquakes in the past week, the country's Meteorological Office said. Seismic data indicated that lava from the volcano was melting ice beneath the Vatnajokull glacier, Iceland's largest, Met Office vulcanologist Melissa Pfeffer said. She said it was not clear when, or if, the eruption would melt through the ice — which is between 100 to 400 meters (330 to 1,300 feet) thick — and send steam and ash into the air. The eruption led Iceland...

Scientists believe the ash from an eruption at Bardarbunga, a huge volcano under Iceland's largest glacier, the Vatnajokull in the south of the country, could disrupt transatlantic and northern European air traffic. They also fear floods from melting ice could cause serious damage to the country's infrastructure. On Tuesday, police announced that they had "decided to close and evacuate the area north of Vatnajokull as a...

Recent examination of lunar and Earth bombardment data indicate that the entire surface of the Earth underwent piecemeal upheavals, hiding our globe's ancient geologic history, and creating a battered world with no remaining familiar land masses. The rain of devastation made it difficult for any life to survive, although bacteria that could endure high temperatures had the best chance.

New images from ESA's Rosetta spacecraft show an odd constriction near the middle of the comet, suggesting that two clumps of matter may have merged in what scientists call a contact binary. The conclusions are preliminary, as Rosetta was still roughly 12,000 kilometers away from the comet when the images were taken. The comet could also have had a more regular single shape with parts carved out through impacts or ice melting as the object circled the sun, mission scientists say. They will have more details about the comet's...

    DNA analysis has debunked the longstanding theory that the Minoans, who some 5,000 years ago established Europe's first advanced Bronze Age culture, were from Africa. The Minoan civilisation arose on the Mediterranean island of Crete in approximately the 27th century BC and flourished for 12 centuries until the 15th century BC. But the culture was lost until British archaeologist Sir Arthur Evans unearthed its remains on Crete in 1900, where he found vestiges of a civilisation he believed was formed by refugees from northern Egypt. Modern archaeologists have cast doubt on that version of events, and now DNA tests of...

    The discovery of thousands of star systems wildly different from our own has demolished ideas about how planets form. Astronomers are searching for a whole new theory. Not so long ago — as recently as the mid-1990s, in fact — there was a theory so beautiful that astronomers thought it simply had to be true. They gave it a rather pedestrian name: the core-accretion theory. But its beauty lay in how it used just a few basic principles of physics and chemistry to account for every major feature of our Solar System. It explained why all the planets orbit the...

    A team from Harvard University presented a study this month that remnants from an ancient Earth exists, right now, inside contemporary Earth. The group believes that their comparisons of isotopic ratios of noble gases from materials deep inside Earth with those near the surface provide testimony that the deep-down material is actually from the Earth that existed before its massive collision with another planet. That immense impact – the largest in geologic history – is what many believe led to creation of the Moon. The currently favored theory about how the Moon originated says that it was formed 4.5 billion...

    Creation stories tend to be outlandish, in keeping with the near impossibility of explaining why the world is the way it is — from the week-long labours of the Old Testament God, to the eternal cycles of the Hindu creator Brahma, to Raven’s metaphysical trickery in Pacific Northwest First Nations tradition. Fanciful as they are, however, these myths have nothing on modern science, whose creation story — which already involves a mysterious Big Bang, perhaps one of many creations ex nihilo in infinite succession — this week got even weirder. At a geophysics conference in California, a series of discoveries...

    Sea levels have been rising and falling without any help from humans for as long as Earth’s oceans have existed. The fastest and most alarming sea changes to affect mankind occurred at the end of the Pleistocene Ice Age. Seas rose about 130m about 12,000 years ago, at times rising at five metres per century. Sea levels then fell as ice sheet and glaciers grew in the recent Little Ice Age – some Roman ports used during the Roman Warm Era are now far from the sea even though sea levels have recovered somewhat during the Modern Warm Era. Many...

    Scientists have discovered a frozen underworld beneath the ice sheet covering northern Greenland. The previously unknown landscape, a vast expanse of warped shapes including some as tall as a Manhattan skyscraper, was found using ice-penetrating radar loaded aboard Nasa survey flights. The findings and the first images of the frozen world more than a mile below the surface of the ice sheet are published on Sunday in the journal Nature Geoscience. ... Until recently, scientists studying the Greenland ice sheet for evidence of change under global warming had thought the shapes they discerned beneath the ice sheet were mountain ranges....

    The remains of a colossal seated statue of Ramses II, thought to be about 13 metres tall and weighing 700 tons, have been discovered in a shanty area of the Upper Egyptian city of Akhmim, adjacent to the open-air museum. The lower part of the limestone statue is seated on a throne, to the right and left of which are figures of two of the pharaoh's daughters and princess- queens, Merit-Amun and Bint-Anath. The statue and the throne are carved from a single block and stand on a huge limestone base covered with carved hieroglyphic texts.

    CAIRO, March 28 (AFP) - Egyptian and German archeologists have discovered the head of a colossal statue which could be an image of Nefertari, the queen of Pharaoh Ramses II, a senior antiquities official said Thursday. The head, discovered in the Nile Delta region of Tel Basta, could also belong to her daughter Princess Merit-Amon, the official said. "The head, in granite, stands 3.5 meters (about 11 feet) high and is 3 meters (about 10 feet) wide, and weighs more than 11 tons," the director of antiquities for the Delta, Mohamed Abdel Maqsoud, told AFP. "These measurements mean that the...

    The Thwaites glacier is one of the most rapidly changing in Antarctica. It’s been the focus of considerable attention in recent weeks, after scientists suggested that this sector of the huge West Antarctic Ice Sheet was already on route towards collapse due to warming ocean temperatures. A major collapse of this part of the ice sheet could have dire consequences worldwide, with a global sea level rise of potentially up to 1m. Some models suggest this could take place comparatively rapidly, within a few centuries. But hidden beneath the kilometres of ice in this rapidly changing part of the...

    On June 8, the 370-meter (about 1,300-ft.) asteroid 2014 HQ124 breezed by Earth at a distance of just 800,000 miles (1.3 million km). Only hours after closest approach, astronomers used a pair of radio telescopes to produce some of the most detailed images of a near-Earth asteroid ever obtained. They reveal a peanut-shaped world called a ‘contact binary’, an asteroid comprised of two smaller bodies touching. About one in six asteroids in the near-Earth population has this type of elongated or “peanut” shape. It’s thought that contact binaries form when two or more asteroids get close enough to touch and...

    Archaeological work on the island of Gökçeada has revealed that an earthquake occurred in the region 4,700 years ago, followed by a tsunami. Çanakkale Onsekiz Mart University Geology Department Professor Doğan Perinçek said they had found the traces of the earthquake and tsunami during works between 2006 and 2008. Gökçek made a statement June 2 after an earthquake measuring 6.5 that occurred on May 24 in the region. He said both he and Professor Halime Hüryılmaz had found traces of an earthquake that occurred in 2680 B.C. following work in the area of Yenibademli. “The earthquake broke the walls of...
