    X-ray observations are consistent with radiowave data reported last month by another team of scientists, who also indicated that it was continuing to brighten during the three months since the collision. During this same period, X-ray and optical observatories were unable to monitor GW170817/GRB because it was too close to the Sun at the time. However, once this period ended, Chandra was able to gather data again, which was consistent with these other observations. As John Ruan explained: “When the source emerged from that blind spot in the sky in early December, our Chandra team jumped at the chance to...
  • 1.7-Billion-Year-Old Chunk of North America Found Sticking to Australia

    Geologists matching rocks from opposite sides of the globe have found that part of Australia was once attached to North America 1.7 billion years ago. Researchers from Curtin University in Australia examinedrocks from the Georgetown region of northern Queensland. The rocks — sandstone sedimentary rocks that formed in a shallow sea — had signatures that were unknownin Australia but strongly resembled rocks that can be seen in present-day Canada. The researchers, who described their findings online Jan. 17 in the journal Geology, concluded that the Georgetown area broke away from North America 1.7 billion years ago. Then, 100 million years...
  • Worst-case global warming scenarios not credible: study

    01/21/2018 10:48:46 PM PST · by Olog-hai · 15 replies
    Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions. A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature. “Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter. How effectively the world slashes CO2 and methane emissions, improves energy efficiency,...

    The most massive galaxies in our neighbourhood formed their stars billions of years ago, early in the history of the universe. At the present day, they produce very few new stars. Astronomers have long believed that is because they contain very little gas – a key ingredient necessary to produce stars. But our new study, published in Nature Astronomy, is now challenging this long held view. Through probing the extreme environments of faraway massive galaxies, we can learn not only about their evolution and the history of the universe, but most importantly about the fundamental processes regulating the formation of...

    [T]he study of GRBs have been complicated by two major issues. On the one hand, GRBs are very short lived, lasting for only seconds at a time. Second, all detected events have occurred in distant galaxies, some of which were billions of light-years away. Nevertheless, there are a few theories as to what could account for them, ranging from the formation of black holes and collisions between neutron stars to extra-terrestrial communications. ... With the assistance of their collaborators in the US, France, the UK and Sweden, the team from Queen’s University Belfast relied on the Gemini laser, located at...

    New work probes the extraterrestrial source of incredibly powerful explosions of radio waves, investigating why that spot is the only known location to repeatedly burst with these blasts.  These repeating bursts may come from a dense stellar core called a neutron star near an extraordinarily powerful magnetic field, such as one near a massive black hole, the study finds. Fast radio bursts, or FRBs, are intense pulses of radio waves lasting just milliseconds that can give off more energy in a fraction of a second than the sun does in hours, days or weeks. FRBs were discovered only in 2007,...

    After California quakes, attention turns to New Madrid zoneATLANTA, Georgia (CNN) -- Recent earthquake activity in California has prompted fresh speculation about "the big one" -- an enormous quake along California's West Coast. A few have been large enough to shake the faith of skeptics -- a magnitude 7.2 quake on June 15, followed two days later by a magnitude 6.7, both off the coast near the California-Oregon border. Doomsayers have warned about the Pacific Coast for years. But only a few have raised concerns about an area with the potential to be more dangerous than California -- the New...

    AN ASTEROID will hurtle towards Earth today – just one week after another dangerously close encounter. The newly-discovered space rock – named Asteroid 2017 TD6 – is expected to zoom past our planet at around at around 7.53pm. It will be travelling at a distance of 191,000km away from civilisation. According to NASA the chunk of rock is a whopping 22m wide. Last week another asteroid made a close shave with Earth, as it soared past at a distance of just 27,000 miles above the surface. And experts have warned a second bus-sized asteroid will zoom past our planet again...

    The scientists now find the asteroid that wiped out the dinosaurs happened to hit an unlucky spot — had it landed in about 87 percent of anywhere else on Earth, the mass extinction might not have occurred. "The probability of the mass extinction occurring was only 13 percent," said study lead author Kunio Kaiho, a geochemist at Tohoku University in Sendai, Japan. The scientists ran computer models simulating the amount of soot that asteroid impacts would have generated depending on the amount of hydrocarbons in the ground. They next estimated the climate effects caused by these different impact scenarios. The...

    After several months of downtime after Hurricane Maria blew through, the Arecibo Observatory Planetary Radar has returned to normal operation, providing the highest-resolution images to date of near-Earth asteroid 3200 Phaethon during its Dec. 16 flyby of Earth. The radar images, which are subtle at the available resolution, reveal the asteroid is spheroidal in shape and has a large concavity at least several hundred meters in extent near the leading edge, and a conspicuous dark, circular feature near one of the poles. Arecibo's radar images of Phaethon have resolutions as fine as about 250 feet (75 meters) per pixel.

  • NASA experts point to Livingston County for potential meteorite discovery

    The search for meteorites continues all over metro Detroit.  NASA experts point toward Livingston County to find them. Bill Cooke is the Meteoroid Environment Program Manager with NASA and he said the Doppler radar images show the meteorites from the meteor spotted on January 16 in Livingston County. “The meteorites should be just south of M-36 between Hamburg and Lakeland,” said Cooke. Cooke said Doppler is best way to track where they might be found. "Doppler weather radar is a very good indicator because, when it picks up meteorites, the meteorites are fairly close to the ground, they're only a couple...

    On February 4, an asteroid called 2002 AJ129 is due to slip past Earth. It is between 1600 and 4000 feet across, according to NASA's Center for Near Earth Object Studies, but there's no chance it will make impact—NASA has calculated it will remain 2.6 million miles away. That still makes it what astronomers call a "potentially hazardous asteroid," thanks to its size being more than about 500 feet across and an orbital path that carries it within about 4,650,000 miles of Earth. But while they're confident we won't all go the way of the dinosaurs, scientists do want to keep an eye on the...

    A huge void discovered inside the Great Pyramid of Giza in Egypt late last year may hold an iron throne carved from meteorites, according to new analysis of ancient religious texts. Giulio Magli, Director of the Department of Mathematics and Professor of Archaeoastronomy at the Politecnico di Milano, studied the Pyramid Texts, religious writings carved into pyramid walls around 2400 BC. Based on his studies, Magli proposes that it’s possible the throne of Pharaoh Khufu – or ‘Cheops’ – lies inside the chamber. ================================================================================================================================ “Of course it would not be melted iron but meteoritic iron, that is, fallen from the...

    Scientists have detected electromagnetic anomalies before major earthquakes, like the magnitude 9.0 event that struck Japan in 2011, triggering a massive tsunami that wiped out coastal communities like Ōfunato, shown above. Can electric signals in Earth’s atmosphere predict earthquakes? By Julia RosenDec. 21, 2015 , 1:45 PM SAN FRANCISCO, CALIFORNIA—Ask seismologists when they’ll be able to predict earthquakes, and the answer is generally: sometime between the distant future and never. Although there have been some promising leads over the years, the history of earthquake forecasting is littered with false starts and pseudoscience. However, some scientists think that Earth’s crust may give hints...

    For 41 years, nothing out of the ordinary has occurred at Dawn Scarpulla’s split-level home, until now. She recently heard a big boom, she says. “I found ice — yellow ice — on my roof,” she tells CBS 2’s Vince Gerasole. The yellow ice broke apart and cracked her ceiling. “When we put the pieces together it was like a five- to six-foot piece of ice, so it was big,” Scarpulla says. She is keeping a sample of the mysterious yellow ice in her garage freezer, for analysis. Planes that land at O’Hare International Airport fly over her home, making...
