    "Solar Rossby waves are gigantic in size, with wavelengths comparable to the solar radius," study co-author Laurent Gizon, of the Max Planck Institute for Solar System Research, said in a statement. (The average radius of the sun is a whopping 432,450 miles, or 696,000 kilometers.) Even so, these waves move very slowly, with shallow troughs and peaks, so they aren't always easy to detect, especially amid the other swirls and disturbances on a body as lively as the sun. … Researchers from the Max Planck Institute for Solar System Research, the University of Göttingen (both in Germany), New York University...

    Asteroid 2010 WC9 will safely pass at about half’s the moon’s distance on Tuesday, May 15, 2018. Estimates of its size range from 197 to 427 feet (60-130 meters), making the May 15 pass one of the closest approaches ever observed of an asteroid of this size. This asteroid was “lost” and then found again. The Catalina Sky Survey in Arizona first detected it on November 30, 2010, and astronomers watched it until December 1, when it became too faint to see. They didn’t have enough observations to track its orbit fully and so predict its return. On May 8,...

    Over the course of the past 200 million years, our planet has experienced four major geological periods (the Triassic, Jurassic and Cretaceous and Cenozoic) and one major ice age (the Pliocene-Quaternary glaciation), all of which had a drastic impact on plant and animal life, as well as effecting the course of species evolution. For decades, geologists have also understood that these changes are due in part to gradual shifts in the Earth’s orbit, which are caused by Venus and Jupiter, and repeat regularly every 405,000 years. But it was not until recently that a team of geologists and Earth scientists...

    Tomb may shed light on 10th plague By Charles M. Sennott, Globe Staff | November 23, 2004 LUXOR, Egypt — Out of the blinding light of a fall morning here in the Valley of the Kings, American archeologist Kent Weeks led the way down a narrow, stone passageway and into the entrance of a tomb. Weeks peered his flashlight into the enveloping darkness of ‘‘the hidden tomb,’’ as he calls it, and pressed on through the damp, winding passages toward what may be his archeological team’s most significant find after years of methodical digging, scraping, and brushing. At the end...

    ...in 1992, a young American graduate student, John Coleman Darnell, and his wife and fellow graduate student, Deborah, decided to take a very different tack. The couple began trekking ancient desert roads and caravan tracks along what they called "the final frontier of Egyptology." Today, John Darnell, an Egyptologist in Yale's Near Eastern Languages and Civilization department, and his team have succeeded in doing what most Egyptologists merely dream of: discovering a lost pharaonic city of administrative buildings, military housing, small industries, and artisan workshops. Says Darnell, of a find that promises to rewrite a major chapter in ancient Egyptian...

    MORE than 270 earthquakes have been recorded in just ten days near Spain’s Canary Islands raising fears of a volcanic eruption. The quakes have struck near Tenerife and Gran Canaria in the Canary Islands where there is a huge submarine fault between the two islands. Spain’s National Geographic Institute said the biggest recent quake reached a magnitude of 3.2 on the Richter scale at only about 35km from Puerto La Luz in Gran Canaria. A report said the fault line has not been active in recent times, but it added, “What if it started spewing magma again? And what if...
  • Did the Biblical city of King David exist? Archaeologists claim they have found ruins(tr)

    A lost city dating to the rule of King David from the Old Testament has been uncovered in Jerusalem. King David is an ancestor of Jesus, according to biblical sources, which say he ruled around BC 1,000. Experts say that recently-found ruins date to the 10th century BC. This ties in with the timeframe for when the bible says King David existed, making the link between the two 'plausible', researchers claim. The finding is likely to fuel the debate surrounding whether Biblical figures such as King David actually existed, however.

  • New theory on origin of the asteroid belt

    Abstract The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally assumed that the belt formed with far more mass and was later strongly depleted. We show that the present-day asteroid belt is consistent with having formed empty, without any planetesimals between Mars and Jupiter's present-day orbits. This is consistent with models in which drifting dust is concentrated into an isolated annulus of terrestrial planetesimals. Gravitational scattering during terrestrial planet formation causes radial spreading, transporting planetesimals from inside 1 to 1.5...
  • 'Interplanetary Shock Wave' Spawns Electric-Blue Auroras

    Space.com ^ | April 21, 2018 08:00am ET | Sarah Lewin,
    A moderate geomagnetic storm kicked up in Earth's skies Friday morning (April 20), bringing green and rare electric-blue auroras that stretched as far south as Indiana. The space-weather news site Spaceweather.com reported that an "interplanetary shock wave" hit Earth's magnetic field at about 3:50 a.m. EDT (2350 on April 19 GMT), quadrupling the intensity of the flow of particles streaming from the sun toward Earth, called the solar wind. The incoming wave of material resulted in a G2-level, or moderate, geomagnetic storm, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC). These types of storms can...

    A large crack that has suddenly appeared in Kenya’s Rift Valley is evidence that Africa will eventually break apart. The crack already stretches several miles and continues to grow, but it does not go all the way across the surface. If it does, it will split the continent into two. The crack has caused part of the Nairobi-Narok highway to collapse and also accelerating seismic activity in the area, leading researchers to believe that something dramatic could happen in the future. “The Great Rift splits Africa into two plates. With what is happening we have established one plate which is...

    https://www.minorplanetcenter.net/db_search/show_object?object_id=2018+GE3 http://spaceweather.com/ SURPRISE ASTEROID FLYBY: With little warning, a relatively large asteroid flew through the Earth-Moon system on April 15th only 192,200 km (0.5 LD) from our planet. 2018 GE3 was discovered by the Catalina Sky Survey approaching Earth on April 14th. Hours later, amateur astronomer Michael Jäger of Weißenkirchen Austria video-recorded the space rock rushing through the southern constellation Serpens: "According to wikipedia, 2018 GE3 is the largest known asteroid to pass that close to Earth in observational history," says Jäger. "It was shining like a 13th magnitude star at the time of my observations." Based on the intensity of its reflected...
  • New study finds: Ancient Mycenaean civilization might have collapsed due to uprising or invasion

    For many years, the prevailing theory on how the Mycenaean civilisation collapsed was that devastating earthquakes led to the destruction of its palaces in the Peloponnese, southern Greece around 1,200 BC. Nevertheless, new evidence suggests that some type of internal uprising or an external invasion might have brought about the downfall of the Mycenaean civilisation. From 2012, a team led by German archaeologist Joseph Maran of Heidelberg University and geophysicist Klaus-G. Hinzen has been conducting research in Tiryns and Midea. The findings of their research were published in the Bulletin of the Seismological Society of America. "Although some of the...

    A series of Earth-shattering volcanic eruptions in Iceland during the Middle Ages may have spurred the people living there to turn away from their pagan gods and convert to Christianity, a new study finds. The discovery came about thanks to precise dating of the volcanic eruptions, which spewed lava about two generations before the Icelandic people changed religions. But why would volcanic eruptions turn people toward monotheism? The answer has to do with the "Voluspa," a prominent medieval poem that predicted a fiery eruption would help lead to the downfall of the pagan gods, the researchers said. Historians have long...

    The unnamed asteroid shares Jupiter's orbital space while moving in the opposite direction as the planet, which looks like a recipe for a collision, astronomers said. Yet somehow, the asteroid has managed to safely dodge Jupiter for at least tens of thousands of laps around the sun, a new study showed. It was given the provisional designation 2015 BZ509 with the nickname "BZ." Scientists noticed that the asteroid moves in the opposite direction of every planet and 99.99 percent of asteroids orbiting the sun, in a state known as retrograde motion. ... BZ may seem like a lucky asteroid, narrowly...
  • Antarctic snowfall increasing, study finds

    Snowfall across the great white continent of Antarctica is increasing, according to a study released this week by an international team led by the British Antarctic Survey. The team analyzed 79 ice cores from across Antarctica that provide detailed information on how much snow has fallen over hundreds of years, and it found a 10% increase in snowfall over the past two centuries. This contradicts studies that found that Antarctic snowfall has remained largely constant over the past several decades to centuries. But those studies analyzed only a few ice cores, whereas this comprehensive look at the continent gives a...
