    The blatant use of science for political gain is not new, but it's clearly getting worse. All kinds of "science" is being used to justify policies that fit a particular political agenda. Case in point: Some Harvard scientists have examined the environmental policies of the Trump administration and concluded that up to 80,000 people a decade will die as a result of political decisions that they disagree with. It used to be that such pronouncements were dismissed as "unscientific." Today, it's front page news.

    If You Think You’re in a Hurry, You Have No Idea How Fast You’re Really Getting There Msgr. Charles Pope • June 5, 2018 • Have you been feeling a little rushed lately? Well, you might be surprised to find out how fast you’re actually moving even when you think you’re “standing still.” Earth, at the latitude of Washington, D.C., is spinning at a rate of about 750 miles per hour [1].At the same time, the spinning Earth is rotating around the Sun at approximately 67,000 miles per hour [2].And the Sun around which we move so rapidly is...
  • Not really a surprise: Science again shows that fracking doesn't pollute groundwater

    Washington Examiner ^ | 05/31/2018 | by Seth Whitehead
    A recent media report on a peer-reviewed study based on 180 samples from water wells near Ohio fracking sites was headlined: “Univ. of Cincy fracking study finds surprising groundwater results.” What exactly was so surprising? The report is one of more than two dozen scientific studies published since 2010 that concluded fracking is not a major threat to groundwater. No fewer than 10 peer-reviewed studies examining more than 3,000 water wells across virtually every major U.S. shale play have been released in the past five years, with each one finding no evidence of that fracking has contaminated groundwater. The reason?...

    At the beginning of the 3rd century civil war raged in Britain as the Roman emperor Septimius Severus sought to quell unrest in the north. But unknown to the fighting cohorts and Caledonian tribes, high above their heads two stars were coming together in a huge cataclysmic explosion. Now 1800 years later the light from that collision will finally arrive on Earth creating a new star in the night sky - dubbed the ‘Boom Star - in an incredibly rare event which is usually only spotted through telescopes. Before their meeting the two stars were too dim to be seen...

    Planetary Society ^ | 6/12/17 | Jason Davis
    Did a Planetary Society citizen scientist help find one of Earth’s biggest impact craters? About 66 million years ago, a 10-kilometer-wide hunk of rock smashed into Earth near what is now Mexico's Yucatán Peninsula.The impact created a global dust cloud that snuffed out the sunlight, leading to the demise of 80 percent of Earth's plants and animals—including most of the dinosaurs. A 200-kilometer-wide crater buried near the city of Chicxulub is all that's left. It's ground zero for one of the world's most notable extinction events.But throughout Earth's history, there have actually been five major extinction events. The largest of...

    BBC ^ | 18 Nov, 2916 | Jonathan Amos BBC Science Correspondent
    Scientists say they can now describe in detail how the asteroid that wiped out the dinosaurs produced its huge crater. The reconstruction of the event 66 million years ago was made possible by drilling into the remnant bowl and analysing its rocks. These show how the space impactor made the hard surface of the planet slosh back and forth like a fluid. At one stage, a mountain higher than Everest was thrown up before collapsing back into a smaller range of peaks. "And this all happens on the scale of minutes, which is quite amazing," Prof Joanna Morgan from Imperial...

    In April of 2016, astronomers became aware of a distant object that appeared to be orbiting the Sun, but was also passing close enough to Earth that it could be periodically viewed using the most powerful telescopes. Since then, there has been ample speculation as to what this “Temporary Moon” could be... ... “While HO3 is close to the Earth, its small size – possibly not larger than 100 feet – makes it challenging target to study. Our observations show that HO3 rotates once every 28 minutes and is made of materials similar to asteroids.” ... Reddy and his colleagues...

    Astronomers have discovered a new “quasi” moon orbiting Earth. 2016 HO3, as the asteroid is called, is at least 40 meters across and could be larger, up to 100 meters, researchers say, but it’s too far from Earth to qualify as a true satellite or mini-moon. "Since 2016 HO3 loops around our planet, but never ventures very far away as we both go around the sun, we refer to it as a quasi-satellite of Earth," said Paul Chodas, manager of NASA's Center for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory in Pasadena, California. "One other asteroid -- 2003...

    University of Copenhagen ^ | Jun 7, 2010 | Unknown
    The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago. But new research from the Niels Bohr Institute shows that the Earth and Moon must have formed much later – perhaps up to 150 million years after the formation of the solar system. The research results have been published in the scientific journal, Earth and Planetary Science Letters. "We have determined the ages of the...

    Back in 2006, the Catalina Sky Survey in Arizona noticed that a mysterious body had begun orbiting the Earth. This object had a spectrum that was remarkably similar to the titanium white paint used on Saturn V rocket stages and, indeed, a number of rocket stages are known to orbit the Sun close to Earth. But this was not an object of ours. Instead, 2006 RH120, as it became known, turned out to be a tiny asteroid just a few metres across--a natural satellite like the Moon. It was captured by Earth's gravity in September 2006 and orbited us...

    New 'moon' found around Earth There could be another one By Dr David Whitehouse BBC News Online science editor An amateur astronomer may have found another moon of the Earth. Experts say it may have only just arrived. Much uncertainty surrounds the mysterious object, designated J002E2. It could be a passing chunk of rock captured by the Earth's gravity, or it could be a discarded rocket casing coming back to our region of space. It was discovered by Bill Yeung from his observatory in Arizona and reported as a passing Near-Earth Object. It was soon realised however that far from...

    "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...

    China has launched a relay satellite to prepare for a lunar rover mission planned for later in the year. The Queqiao spacecraft will establish a communications link between Earth and the landing mission, which looks set to launch in the next six months. The satellite was launched at 22:28 BST on Sunday (05:28 local time) from Xichang launch centre in the country's south-west. It will settle in an orbit about 455,000 km (282,555 miles) from Earth. This orbit will also take it more than 60,000 km from the lunar farside, where China will aim to put down with a lander...

    A tiny satellite on its way to Mars has opened its eyes and captured a view of home. One of NASA's two Mars Cube One (MarCO) cubesats, which launched toward the Red Planet along with the agency's InSight lander on May 5, took a photo on May 9 to help confirm that its high-gain antenna had deployed properly. The antenna is in the photo. And so are the moon and Earth, the latter of which appears as a pale blue dot, just as it did in a famous photo taken by NASA's Voyager 1 probe in 1990. ..."

    One month after its launch, NASA’s Transiting Exoplanet Survey Satellite has sent back an initial test image that shows more than 200,000 stars in the southern sky. TESS’ image was taken by one of its cameras with a two-second exposure. The picture is centered on the constellation Centaurus, with the edge of the dark Coalsack Nebula at upper right and the star Beta Centauri prominent along the lower edge. The picture provides only a hint of what TESS will be seeing once it starts delivering science-quality images next month. When all four wide-field cameras are in operation, TESS’ images...

    Next Big Future ^ | May 16, 2018 | Brian Wang
    Researchers have been able to confine light down to a space one atom, the smallest possible. This will pave the way to ultra-small optical switches, detectors and sensors. Light can function as an ultra-fast communication channel, for example between different sections of a computer chip, but it can also be used for ultra-sensitive sensors or on-chip nanoscale lasers. There is currently much research into how to further shrink devices that control and guide light. New techniques searching for ways to confine light into extremely tiny spaces, much smaller than current ones, have been on the rise. Researchers had previously found...
