    Listen up, NASA. Stephen Hawking has said it before and he’ll say it again: If extraterrestrials call, do not answer ― at least, not without careful consideration. Well, we’re convinced. NASA, we really hope you’re listening.

    Her actual performance in the chess world shows these to be puff pieces with very little attention paid to empirical fact. Mutesi has no doubt achieved something as a young Ugandan girl living in poverty, to capture the attention of the world, but that something she accomplished is not being good at chess. She achieved her highest chess rating in 2012, a 1686, as listed by FIDE. As of September 2016, her rating has dropped to 1622. FIDE lists that from the 40th Olympiad in 2012, to April 2016, she played a grand total of 39 matches and never scored...

  • In rotating galaxies, distribution of normal matter precisely determines gravitational acceleration

    Science Daily ^ | September 21, 2016 | Case Western Reserve University
    Now a team led by Case Western Reserve University researchers has found a significant new relationship in spiral and irregular galaxies: the acceleration observed in rotation curves tightly correlates with the gravitational acceleration expected from the visible mass only. "Galaxy rotation curves have traditionally been explained via an ad hoc hypothesis: that galaxies are surrounded by dark matter," said David Merritt, professor of physics and astronomy at the Rochester Institute of Technology, who was not involved in the research. "The relation discovered by McGaugh et al. is a serious, and possibly fatal, challenge to this hypothesis, since it shows that...

    Black men may have a legitimate reason to flee Boston police during investigatory or Terry stops, the Massachusetts Supreme Judicial Court ruled Tuesday. The court found that systemic racism in the Boston Police Department may be considered in conjunction with a suspects decision to flee from police during a stop. A Terry stop, named for the U.S. Supreme Court case which sanctioned the practice, refers to a brief detention and search of an individual due to reasonable suspicion of criminal conduct. In this case, a black male named Jimmy Warren was arrested in 2011

    BBC ^ | 9/14/16 | Jonathan Amos
    The most precise map of the night sky ever assembled is taking shape. Astronomers working on the Gaia space telescope have released a first tranche of data recording the position and brightness of over a billion stars. And for some two million of these objects, their distance and sideways motion across the heavens has also been accurately plotted. Gaia's mapping effort is already unprecedented in scale, but it still has several years to run. Remarkably, scientists say the store of information even now is too big for them to sift, and they are appealing for the public's help in making...

    Some meteorites are so big they need a name. Meet the Gancedo meteorite, a gigantic space rock extracted from the ground over the weekend using heavy machinery. It was found near the village of Gancedo in Argentina in an area known as Campo del Cielo ("Field of Heaven"). Campo del Cielo is rife with iron meteorites estimated to have fallen around 4,000 years ago. What makes Gancedo unusual is its massive size, with a weight estimated at around 68,000 pounds (31,000 kilograms). News organization Compacto Nea posted a video of the meteorite extraction on YouTube Monday. It was a complicated...

As chemical compounds go, it is quite exotic, and chemists are still not sure how to create it under laboratory conditions. But it just so happens that this acid could exist in the interiors of planets like Uranus and Neptune. According to a recent study from a team of Russian chemists, the conditions inside Uranus and Neptune could be ideal for creating exotic molecular and polymeric compounds, and keeping them under stable conditions. The study was produced by researchers from the Moscow...

    When astronomers discovered a strange pattern of light near a distant star called KIC 8462852 back in October, it was like nothing anyone had observed before. When a planet passes in front of star, the stars brightness usually dips by around 1 percent, but KIC 8462852 has been experiencing dips of up to 22 percent, suggesting that something huge is zooming past. And now a second star with strange dips in brightness has been identified. Named EPIC 204278916, the star is estimated to be about the size of our Sun in diameter, but has only half its mass. It was...

    Brazilian sky watchers had only just discovered the asteroid, called 2016 QA2, the day before it zoomed by within 50,000 miles (80,000 km) of Earth. That's less than a quarter of the distance between Earth and the moon. Astronomers at the Sonear observatory in Brazil discovered the rock on Saturday 27th August, and estimate its size to be between 80 and 180 feet wide (25 and 55 metres). The upper end of the range would make it far larger than the object which exploded over Chelyabinsk in Russia in 2013, smashing windows and injuring more than 1,000 people. he team...

    In a paper that was recently accepted by The Astronomical Journal, Sheppard and Trujillo present their latest discoveries, which they claim are further constraining the location of Planet 9. ...Sheppard and Trujillo relied on information obtained by the Dark Energy Camera on the Victor Blanco 4-meter telescope in Chile and the Japanese Hyper Suprime-Camera on the 8-meter Subaru Telescope in Hawaii. ... Their most recent discovery was a small collection of more extreme objects whos peculiar orbits differ from the extreme and inner Oort cloud objects, in terms of both their eccentricities and semi-major axes. As with discoveries made using...

In 2012 an annular eclipse of the Sun was visible over a narrow path that crossed the northern Pacific Ocean and several western US states. In an annular solar eclipse, the Moon is too far from the Earth to block out the entire Sun, leaving the Sun...
  • Earth Just Narrowly Missed Getting Hit by an Asteroid

    Popular Mechanics ^ | 8/30/2016 | Avery Thompson
    On Saturday, astronomers discovered a new asteroid, just a few hours before it almost hit us. The asteroid is called 2016 QA2, and it missed the Earth by less than a quarter of the distance to the moon. That puts it about three times as far away from Earth as our farthest satellites. And we never saw it coming. So how did 2016 QA2 sneak up on us like that? For this particular asteroid, the answer seems to be that it has a very peculiar orbit. It's highly elliptical, which means it can usually be found hanging out by either...

    The Solar storm of August 28 to September 2, 1859known as the Carrington Eventwas a powerful geomagnetic solar storm during solar cycle 10 (18551867). A solar coronal mass ejection(CME) hit Earth's magnetosphere and induced one of the largest geomagnetic storms on record. The flare traveled directly toward Earth, taking 17.6 hours to make the 150 million kilometer (93 million mile) journey. It is believed that the relatively high speed of this CME (typical CMEs take several days to arrive at Earth) was made possible by a prior CME, perhaps the cause of the large aurora event on August 29, that...

    The center of the Milky Way galaxy is currently a quiet place where a supermassive black hole slumbers, only occasionally slurping small sips of hydrogen gas. But it wasn't always this way. A new study shows that 6 million years ago, when the first human ancestors known as hominins walked the Earth, our galaxy's core blazed forth furiously. The evidence for this active phase came from a search for the galaxy's missing mass.

    The signals seem to be coming from a sun-like star known as HD 164595 The star is 95 light years away and may have undiscovered planets in orbit Scientists say signals may simply be the result of a natural phenomenon One possibility is 'microlensing' in which the star's gravity focuses signals coming from farther away A spike in radio signals coming from the direction of a sun-like star has excited astronomers. The signals seem to be originating from a sun-like star known as HD 164595 in the constellation Hercules, around 95 light years away. Scientists suggest they are likely to...

    An Interesting SETI Candidate in Hercules by Paul Gilster on August 27, 2016 A candidate signal for SETI is a welcome sign that our efforts in that direction may one day pay off. An international team of researchers has announced the detection of a strong signal in the direction of HD164595 in a document now being circulated through contact person Alexander Panov. The detection was made with the RATAN-600 radio telescope in Zelenchukskaya, in the KarachayCherkess Republic of Russia, not far from the border with Georgia in the Caucasus. The signal was received on May 15, 2015, 18:01:15.65 (sidereal time),...
