  • Solar System Ice: Source of Earth's Water

    Carnegie Institution ^ | Thursday, July 12, 2012 | unattributed
    Scientists have long believed that comets and, or a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth's volatile elements -- which include hydrogen, nitrogen, and carbon -- and possibly organic material, too. Understanding where these volatiles came from is crucial for determining the origins of both water and life on the planet. New research led by Carnegie's Conel Alexander focuses on frozen water that was distributed throughout much of the early Solar System, but probably not in the materials that aggregated to initially form Earth... It has been suggested that both comets and carbonaceous...

    JUST months - that's how long it took for Europe to be engulfed by an ice age. The scenario, which comes straight out of Hollywood blockbuster The Day After Tomorrow, was revealed by the most precise record of the climate from palaeohistory ever generated. Around 12,800 years ago the northern hemisphere was hit by the Younger Dryas mini ice age, or "Big Freeze". It was triggered by the slowdown of the Gulf Stream, led to the decline of the Clovis culture in North America, and lasted around 1300 years. Until now, it was thought that the mini ice age took...

    ALBUQUERQUE, N.M. - An asteroid that exploded over Siberia a century ago, leaving 800 square miles of scorched or blown down trees, wasn't nearly as large as previously thought, a researcher concludes, suggesting a greater danger for Earth. According to supercomputer simulations by Sandia National Laboratories physicist Mark Boslough, the asteroid that destroyed the forest at Tunguska in Siberia in June 1908 had a blast force equivalent to one-quarter to one-third of the 10- to 20-megaton range scientists previously estimated. Better understanding of what happened at Tunguska will allow for better estimates of risk that would allow policymakers to decide...

    ...the planets weren't always in the order they are today. Four billion years ago, early in the solar system's evolution, Uranus and Neptune switched places. This is the result of recent work by Steve Desch, assistant professor in the School of Earth and Space Exploration at Arizona State University. The work appears in this week's Astrophysical Journal. Desch based his conclusion on his calculations of the surface density of the solar nebula. The solar nebula is the disk of gas and dust out of which all of the planets formed. The surface density -- or mass per area -- of...

    One day in a spring, an elderly man walked alone on a stone road lined by young willows in Xuzhou in East China's Jiangsu Province. At the end of the road was a museum that few people have heard of. A Chinese theology professor says the first Christmas is depicted in the stone relief from the Eastern Han Dynasty (AD 25-220). In the picture above a woman and a man are sitting around what looks like a manger, with allegedly "the three wise men" approaching from the left side, holding gifts, "the shepherd" following them, and "the assassins" queued...

    King Tut's necklace shaped by fireball June 26, 2006 LONDON: Scientists believe they have solved the mystery surrounding a piece of rare natural glass at the centre of an elaborate necklace found among the treasures of Tutankhamun, the boy pharaoh. They think a fragile meteorite broke up as it entered the atmosphere, producing a fireball with temperatures over 1800C that turned the desert sand and rock into molten lava that became glass when it cooled. Experts have puzzled over the origin of the yellow-green glass -- carved into the shape of a scarab beetle -- since it was excavated in...

    There occurred violent earthquakes and floods. And in a single day and night of misfortune... the island of Atlantis disappeared in the depths of the sea." This account, written by Plato more than 2,300 years ago, set scientists on the trail of the lost city of Atlantis. Did it ever exist? And if so, where was it located, and when did it disappear? In a recent paper in Geology, Marc-Andre Gutscher of the European Institute for Marine Studies in Plouzané gives details of one candidate for the lost city: the submerged island of Spartel, west of the Straits of Gibraltar....

    On 26 May, JPL's unique orbital calculation software determined that Comet Catalina was on what could possibly be a collision course with Earth, though the odds of such an impact were small: just 1 chance in 300,000 of a strike on June 11, 2085. Based on the 980-metre size estimate, that would produce a 6-gigaton impact - equivalent to 6 billion tonnes of TNT. Astronomers expected the addition of further observations to the calculations to rule out any possibility of a collision, as happens with most newly-seen objects. But that did not quite happen. The comet's predicted pathway actually drew...

    Jafar Arkani-Hamed of McGill University discovered that five impact basins--dubbed Argyre, Hellas, Isidis, Thaumasia and Utopia--form an arclike pattern on the Martian surface. Three of the basins are well-preserved and remain visible today. The locations of the other two, in contrast, were inferred from measurements of anomalies in the planet's gravitational field... a single source--most likely an asteroid that was initially circling the sun in the same plane as Mars--created all five craters. At one point the asteroid passed close to the Red Planet... and was broken apart by the force of the planet's gravity. The resulting five pieces subsequently...

    Chance Of A Cometary Impact Re-assessedThe chances of the Earth suffering a collision with a cometary body may be higher than previously thought, according to new research by astronomers Bill Napier and Chandra Wickramasinghe. If so, international programmes designed to detect a large class of potentially threatening objects, namely near-Earth asteroids, as well as strategies to mitigate the worst effects of collisions, may be in need of urgent review. This is the disturbing conclusion reached by the astronomers in a paper which is to be published shortly in the Monthly Notices of the Royal Astronomical Society. Their argument is based...

    Early in the evening of June 18, 1178, a group of men near Canterbury, England, stood admiring the sliver of a new moon hanging low in the west. In terms they later described to a monk who recorded their sighting, "Suddenly a flaming torch sprang from the moon, spewing fire, hot coals and sparks."

    An impact event occurred at 2.15±0.5 Ma in the Bellingshausen Sea. It littered the oceanic floor with asteroidal debris. This debris is found within the Eltanin Impact Layer. Although the impact layer was known, the crater had yet to be discovered. We have found a possible source crater at 53.7S,90.1W under 5000 meters of water. The crater is 132±5km in diameter, much larger than the previously proposed size of 24 to 80 km.

    1. Introduction As related by Clube and Napier in their monograph The Cosmic Winter, see [1], in the year 1178 A.D. four wise men of Canterbury were sitting outside on a clear and calm 18th June night, a half Moon standing placidly in the starry sky. Suddenly they noticed a flame jutting out of a horn of the Moon. Then they saw the Moon tremble and its colour change slowly from light brilliant to a darker reddish tone. Such a colour remained for all the time the Moon was visible during that phase. This story is found in a manuscript...

    50 ancient tombs uncovered From correspondents in Athens July 18, 2004 ARCHEOLOGISTS have discovered 50 tombs dating back to the late Minoan period, around 1400 BC, and containing a number of artifacts on the Greek island of Crete, ANA news agency reported today. The tombs were part of the once powerful ancient city of Kydonia, which was destroyed at the time but later rebuilt. The oldest among them contained bronze weapons, jewellery and vases and are similar to the tombs of fallen soldiers of the Mycenaean type from mainland Greece, said the head of the excavations, Maria Vlazaki.

    (Phys.org)—When a huge meteor collided with Earth about 2.5 million years ago in the southern Pacific Ocean it not only likely generated a massive tsunami but also may have plunged the world into the Ice Ages, a new study suggests. A team of Australian researchers says that because the Eltanin meteor – which was up to two kilometres across - crashed into deep water, most scientists have not adequately considered either its potential for immediate catastrophic impacts on coastlines around the Pacific rim or its capacity to destabilise the entire planet's climate system. "This is the only known deep-ocean impact...

    DUBLIN (Reuters) - Atlantis, the legendary island nation over whose existence controversy has raged for thousands of years, was actually Ireland, according to a new theory by a Swedish scientist. Atlantis, the Greek philosopher Plato wrote in 360 BC, was an island in the Atlantic Ocean where an advanced civilization developed some 11,500 years ago until it was hit by a cataclysmic natural disaster and sank beneath the waves. Geographer Ulf Erlingsson, whose book explaining his theory will be published next month, says the measurements, geography, and landscape of Atlantis as described by Plato match Ireland almost exactly.
