Explanation: In the center of a swirling whirlpool of hot gas is likely a beast that has never been seen directly: a black hole. Studies of the bright light emitted by the swirling gas frequently indicate not only that a black hole is present, but also likely attributes. The gas surrounding GRO J1655-40, for example, has been found to display an unusual flickering at a rate of 450 times a second. Given a previous mass estimate for the central object of seven times the mass of our Sun, the rate of the fast flickering can be explained by a black...

Junk Science: Climate change "deniers," as global warm-mongers call those who think empirical evidence is more reliable than computer models, may soon count among their number a 50,000-strong body of physicists. At the risk of being accused of embracing what alarmists call the flat-earth view of climate change, the American Physical Society has appointed a balanced, six-person committee to review its stance on so-called climate change that includes three distinguished skeptics: Judith Curry, John Christy and Richard Lindzen. Their credentials are impressive. Christy is director of the Earth System Science Center at the University of Alabama, Huntsville, and was a...

Explanation: Deep shadows create dramatic contrasts between light and dark in this high-resolution close-up of the martian surface. Recorded on January 24 by the HiRISE camera onboard the Mars Reconnaissance Orbiter, the scene spans about 1.5 kilometers across a sand dune field in a southern highlands crater. Captured when the Sun was just 5 degrees above the local horizon, only the dune crests are caught in full sunlight. With the long, cold winter approaching the red planet's southern hemisphere, bright ridges of seasonal frost line the martian dunes.

The American Physical Society (APS) has signalled a dramatic turnabout in its position on "climate change" by appointing three notorious climate skeptics to its panel on public affairs (POPA). If that list looks impressive, perhaps it's worth reminding ourselves of Hal Lewis's theory as to why so many scientific institutions have fallen for the scam. There are indeed trillions of dollars involved, to say nothing of the fame and glory (and frequent trips to exotic islands) that go with being a member of the club. Your own Physics Department (of which you are chairman) would lose millions a year if...

Explanation: Towering 3,000 feet from base to summit, the famous granite face of El Capitan in Earth's Yosemite National Park just hides the planet's north celestial pole in this skyscape. Of course, the north celestial pole is at the center of all the star trails. Their short arcs reflecting the planet's daily rotation on its axis are traced in a digital stack of 36 sequential exposures. Linear trails of passing airplane navigation lights and a flare from car lights along the road below are also captured in the sequential stack. But the punctuated trail of light seen against the sheer...

Explanation: Today is the equinox. The Sun crosses the celestial equator heading north at 16:57 UT, marking the northern hemisphere's first day of spring. To celebrate, consider this remarkable image following the Sun's yearly trek through planet Earth's sky, the first analemmas exposed every day through the technique of solargraphy. In fact, three analemma curves were captured using a cylindrical pinhole camera by daily making three, separate, one minute long exposures for a year, from March 1, 2013 to March 1, 2014, on a single piece of black and white photographic paper. The well-planned daily exposures began at 10:30, 12:00,...

Explanation: When does the line between day and night become vertical? Tomorrow. Tomorrow is an equinox on planet Earth, a time of year when day and night are most nearly equal. At an equinox, the Earth's terminator -- the dividing line between day and night -- becomes vertical and connects the north and south poles. The above time-lapse video demonstrates this by displaying an entire year on planet Earth in twelve seconds. From geosynchronous orbit, the Meteosat satellite recorded these infrared images of the Earth every day at the same local time. The video started at the September 2010 equinox...

“Maybe we can reach a point of reconsideration” on Uganda’s Anti-Homosexuality Bill, Kerry said during a forum at the State Department. The Ugandan president committed to meeting with American “experts” on homosexuality to try to change his mind about the Anti-Homosexuality Act signed into law last month, U.S. Secretary of State John Kerry said on Tuesday during a forum at the State Department moderated by BuzzFeed. Museveni claimed to have signed the law, which imposes up to a lifetime prison sentence for homosexuality, after being convinced no one is “born gay.” “I talked personally to President Museveni just a few...

On ABC, America’s Funniest Home Videos garnered a 1.4, down 7 percent from a 1.5 adults 18-49 rating for its most recent original. ......................................................... Cosmos earned a 1.9 adults 18-49 rating down 10 percent from a 2.1 for last week’s premiere.

Explanation: Did the universe undergo an early epoch of extremely rapid expansion? Such an inflationary epoch has been postulated to explain several puzzling cosmic attributes such as why our universe looks similar in opposite directions. Yesterday, results were released showing an expected signal of unexpected strength, bolstering a prediction of inflation that specific patterns of polarization should exist in cosmic microwave background radiation -- light emitted 13.8 billion years ago as the universe first became transparent. Called B-mode polarizations, these early swirling patterns can be directly attributed to squeeze and stretch effects that gravitational radiation has on photon-emitting electrons. The...

Is misinformation about the climate criminally negligent? Lawrence Torcello, PHILOSPHY professor thinks so. "The importance of clearly communicating science to the public should not be underestimated. Accurately understanding our natural environment and sharing that information can be a matter of life or death. When it comes to global warming, much of the public remains in denial about a set of facts that the majority of scientists clearly agree on. With such high stakes, an organised campaign funding misinformation ought to be considered criminally negligent.

It won't be nearly as much fun as eating candy bars, but a big study is being launched to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes. The pills are so packed with nutrients that you'd have to eat countless candy bars to get the amount being tested in this study, which will enroll 18,000 men and women across the U.S. ``People eat chocolate because they enjoy it,'' not because they think it's good for them, and the idea of the study is to see whether there are health benefits from chocolate's...

Explanation: What's happened to the sky? A time warp, of sorts, and a digital space warp too. The time warp occurs because this image captured in a single frame a two and a half hour exposure of the night sky. As a result, prominent star trails are visible. The space warp occurs because the picture is actually a full 360 degree panorama, horizontally compressed to fit your browser. As the Earth rotated, stars appeared to circle both the North Celestial Pole, on the left, and the South Celestial Pole, just below the horizon on the right. The above panorama over...

Explanation: Two galaxies are squaring off in Corvus and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. That's because galaxies are mostly empty space and, however bright, stars only take up only a small amount of that space. During the slow, hundred million year collision, one galaxy can still rip the other apart gravitationally, and dust and gas common to both galaxies does collide. In this clash of the titans, dark dust pillars mark massive molecular clouds are being compressed during the galactic encounter, causing the rapid birth of millions of...

... American science, long a source of national power and pride, is increasingly becoming a private enterprise. In Washington, budget cuts have left the nation’s research complex reeling. Labs are closing. Scientists are being laid off. Projects are being put on the shelf, especially in the risky, freewheeling realm of basic research. Yet from Silicon Valley to Wall Street, science philanthropy is hot, as many of the richest Americans seek to reinvent themselves as patrons of social progress through science research. ... Fundamentally at stake, the critics say, is the social contract that cultivates science for the common good. They...

Explanation: Get out your red/blue glasses and check out this stereo scene from Taurus-Littrow valley on the Moon! The color anaglyph features a detailed 3D view of Apollo 17's Lunar Rover in the foreground -- behind it lies the Lunar Module and distant lunar hills. Because the world was going to be able to watch the Lunar Module's ascent stage liftoff via the rover's TV camera, this parking place was also known as the VIP Site. In December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours on the Moon, while colleague Ronald Evans orbited...

Explanation: NGC 2685 is a confirmed polar ring galaxy - a rare type of galaxy with stars, gas and dust orbiting in rings perpendicular to the plane of a flat galactic disk. The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring. Still, observed properties of NGC 2685 suggest that the rotating ring structure is remarkably old and stable. In this sharp view of the peculiar system also known as Arp 336 or the Helix galaxy, the strange, perpendicular rings are...

The director of the U.S. government office that monitors scientific misconduct in biomedical research has resigned after 2 years out of frustration with the “remarkably dysfunctional” federal bureaucracy. David Wright, director of the Office of Research Integrity (ORI), writes in a scathing resignation letter obtained by ScienceInsider that the huge amount of time he spent trying to get things done made much of his time at ORI “the very worst job I have ever had.” ORI, which is part of the Department of Health and Human Services (HHS), monitors alleged research misconduct by researchers funded by the National Institutes of...

Genesis Science Is Practical, Not Just Academic by James J. S. Johnson, J.D., Th.D. * “It doesn’t really matter, in the real world, what you believe about creation or evolution,” the college student glibly challenged me. “Whether the evolutionists are right or whether Genesis is right makes no practical difference in how science works or in how people live their lives.” With a grin and a wave of his hand, the sophomore dismissed the real-world relevance of biblical creation as if it were no more practical than evolutionary myths. Was he correct? Is the Genesis record of God’s creation (and...

Explanation: A bright spiral galaxy of the northern sky, Messier 63 is about 25 million light-years distant in the loyal constellation Canes Venatici. Also cataloged as NGC 5055, the majestic island universe is nearly 100,000 light-years across. That's about the size of our own Milky Way Galaxy. Known by the popular moniker, The Sunflower Galaxy, M63 sports a bright yellowish core in this sharp, colorful galaxy portrait. Its sweeping blue spiral arms are streaked with cosmic dust lanes and dotted with pink star forming regions. A dominant member of a known galaxy group, M63 has faint, extended features that could...
