    The inscription discovered in the new excavations is nothing more than a scrawl in charcoal, likely made by a worker renovating a home. But it is dated to 16 days before the "calends" of November in the old Roman calendar style - which is 17 October in our modern dating method. "Since it was done in fragile and evanescent charcoal, which could not have been able to last long, it is highly probable that it can be dated to the October of AD 79," the archaeology team said in a statement. They believe the most likely date for the eruption...

    On a lush hilltop deep in Southern Ohio, a giant snake slithers through the grass, its intentions a mystery. Despite more than a century of study, we still don't know who built the Great Serpent Mound, or why. That's part of what makes a visit here so fascinating, and also a little bit frustrating. There are still questions that can't be answered through a Google search or more than a century of research. This much is known: At 1,348 feet long, the serpent is the largest effigy mound in the world -- that is, an earthen creation in the shape...

    Situated in the building known as 'House of Desks' -- near the spot where the exquisite golden ibex was found in 1999 -- the finds include a marble protocycladic female figurine, two small marble protocycladic collared jars, a marble vial and an alabaster vase, which were found inside clay chests of rectangular shape. According to a culture ministry statement, the finds were made under rubble inside a large and probably public building that is south of Xeste 3, near where the golden ibex now on display at the Museum of Prehistoric Thira was also found in a clay chest beside...

    “Fossils do not represent the only line of evidence to understand the past. A second record of life exists, preserved in the genomes of all living creatures,” said co-author Professor Philip Donoghue, from the School of Earth Sciences at the University of Bristol.“Combining fossil and genomic information, we can use an approach called the ‘molecular clock’ which is loosely based on the idea that the number of differences in the genomes of two living species (say a human and a bacterium) are proportional to the time since they shared a common ancestor,” added co-author Dr. Tom Williams, also from the...

    Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our Solar System. The object, about a dozen times more massive than Jupiter, is a surprisingly strong magnetic powerhouse and a "rogue," traveling through space unaccompanied by any parent star. "This object is right at the boundary between a planet and a brown dwarf, or 'failed star,' and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets," said Melodie Kao, who led this study while a graduate...
  • Massive glowing 'rogue' planet spotted 'drifting' in space

    A massive glowing "rogue" planetary-mass object has been discovered, surprising scientists with not only its size, but also the fact it's not orbiting a star. The object, named SIMP J01365663+0933473, has a magnetic field more than 200 times stronger than Jupiter’s and is nearly 13 times the size of the gas giant. At its size, it's right between the size of a planet and a failed star, so scientists will need to study it further to determine exactly what it is. “This object is right at the boundary between a planet and a brown dwarf, or ‘failed star,’ and is...
  • Bizarre Rogue 'Planet' with Incredible Auroras Puzzles Scientists

    A rogue, planet-size object 20 light-years away from Earth has stunned astronomers with its incredibly powerful magnetic field. The scientists found that the object's magnetic field is more than 200 times stronger than Jupiter's, which, in turn, is between 16 and 54 times stronger than Earth's, according to NASA. How the object, which scientists call SIMP J01365663+0933473, can maintain a magnetic field so strong, as well as generate spectacular auroras, is still unclear. "This particular object is exciting because studying its magnetic dynamo mechanisms can give us new insights on how the same type of mechanisms can operate in extrasolar...

    A bizarre rogue planet without a star is roaming the Milky Way just 20 light-years from the Sun. And according to a recently published study in The Astrophysical Journal, this strange, nomadic world has an incredibly powerful magnetic field that is some 4 million times stronger than Earth’s. Furthermore, it generates spectacular auroras that would put our own northern lights to shame. The new observations, made with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA), not only are the first radio observations of a planetary-mass object beyond our solar system, but also mark the first time...
  • Did the Mysterious 'Planet Nine' Tilt the Solar System?

    In January, astronomers revealed evidence for the potential existence of another planet in the solar system. Researchers suggest that if this world — dubbed Planet Nine — exists, it could be about 10 times Earth's mass and orbit the sun at a distance about 500 times the distance from the Earth to the sun. Previous research suggested that Planet Nine would possess a highly tilted orbit compared with the relatively thin, flat zone in which the eight official planets circle the sun. This led scientists to investigate whether Planet Nine's slant might help explain other tilting seen elsewhere in the...

    “Of the seven million Gaia stars with full 3D velocity measurements, we found twenty that could be traveling fast enough to eventually escape from the Milky Way,” said team member Dr. Elena Maria Rossi, an astronomer at Leiden Observatory.“Rather than flying away from the Galactic center, most of the high velocity stars we spotted seem to be racing towards it,” added team leader Dr. Tommaso Marchetti, also from Leiden Observatory.“These could be stars from another galaxy, zooming right through the Milky Way.”It is possible that these intergalactic interlopers come from the Large Magellanic Cloud, a relatively small galaxy orbiting the...
  • Stunning volcanic 'lost world' discovered deep in the ocean

    Scientists have discovered a stunning volcanic ‘lost world’ off the coast of Tasmania. Experts on the Commonwealth Scientific and Industrial Research Organisation (CSIRO), vessel ‘Investigator’ made the find while mapping the seafloor 249 miles east of Tasmania. The project is led by scientists from the Australian National University. CSIRO is Australia’s national science agency. A chain of ‘seamounts’, or undersea mountains, were spotted in deep water, offering the first glimpse of a spectacular “underwater world.” Scientists say that the mountains rise up to 9,843 feet from the seafloor, but the highest peaks are still 6,562 feet beneath the waves. “Our...

The image at the top of the inscription appears to show the king Seti I with the gods Horus and Sobek.A giant stone engraving that fits together like a jigsaw puzzle, found in a temple in southern Egypt, may reveal new information about a pharaoh named Seti I, who launched a series of military campaigns in North Africa and the Middle East after he became pharaoh in about 1289 or 1288 B.C., several Egyptologists told Live Science. The engraving has both drawings and hieroglyphs...

    Source: CNN A magnitude 5.9 earthquake struck near Haiti on Saturday night, according to the US Geological Survey. There was damage in the northern sections of the country, President Jovenel Moïse tweeted. snip... The USGS said the center of the quake was about 11 miles northwest of the city of Port-de-Paix. It was only 7.2 miles deep. In January 2010, a 7.1 magnitude earthquake killed an estimated 220,000 to 300,000 people in Haiti. Tens of thousands of people are still displaced as a result of the quake.

Mona Sirbescu, a CMU geology professor, gets asked all the time by people to examine the rocks they bring her — but none ever turn out to be an official space rock. “For 18 years, the answer has been categorically ‘no’ — meteor wrongs, not meteorites,” Sibescu said in a statement from CMU on Thursday. But that all changed when she was asked to examine an oddly shaped large rock that a...

    The tip of a bone point fragment found embedded in a mastodon rib from an archaeological site in Washington state shows that hunters were present in North America at least 800 years before Clovis, confirming that the first inhabitants arrived earlier to North America than previously thought, says a team of researchers led by a Texas A&M University archaeologist. Michael Waters, director of the Center for the Study of the First Americans in the Department of Anthropology at Texas A&M, and colleagues from Colorado, Washington and Denmark believe the find at the Manis site in Washington demonstrates that humans were...

    Sept. 27, 2018: The sun is entering one of the deepest Solar Minima of the Space Age. Sunspots have been absent for most of 2018, and the sun’s ultraviolet output has sharply dropped. New research shows that Earth’s upper atmosphere is responding. “We see a cooling trend,” says Martin Mlynczak of NASA’s Langley Research Center. “High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold.” To help keep track of what’s happening in the thermosphere, Mlynczak and colleagues recently introduced the...
  • The disks of gas and dust that supposedly form planets don’t seem to have the goods

    09/30/2018 12:34:32 PM PDT · by ETL · 30 replies ^ | Sept 28, 2018 | Adam Mann
    Astronomers have a problem on their hands: How can you make planets if you don’t have enough of the building blocks? Stars are born from colossal clouds of gas and dust and, in their earliest stages, are surrounded by a thin disk of material. Dust grains within this halo collide, sometimes sticking together. The clumps build up into planetary cores, which are big enough to gravitationally attract additional dust and gas, eventually forming planets. But many details about this process remain unknown, such as just how quickly planets arise from the disk, and how efficient they are in capturing material....
