Explanation: The first identified compact galaxy group, Stephan's Quintet is featured in this remarkable image constructed with data drawn from Hubble Legacy Archive and the Subaru Telescope on the summit of Mauna Kea. The galaxies of the quintet are gathered near the center of the field, but really only four of the five are locked in a cosmic dance of repeated close encounters taking place some 300 million light-years away. The odd man out is easy to spot, though. The interacting galaxies, NGC 7319, 7318A, 7318B, and 7317 have a more dominant yellowish cast. They also tend to have distorted...

Astronomers have nicknamed a new dwarf planet circling the sun at the outer edges of the solar system after Vice President Joe Biden. According to Nature, a leading scientific journal, the object's official designation is 2012 VP113. But the team studying its orbit around the sun colloquially refer to the planet as just "VP" or "Biden," after the sitting vice president. The object won't carry an official title until scientists collect more data. After determining its orbit, they'll submit a formal name to the International Astronomical Union (IAU) for consideration. The Biden dwarf is the second such object to be...

Explanation: An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Of the two reflection nebulas pictured above, the more famous nebula is M78, in the image center, while NGC 2071 can be seen to its lower left. The same type of scattering that colors the daytime sky further enhances the blue color. M78 is about five light-years across and visible through a small...

Explanation: What surrounds a hotbed of star formation? In the case of the Orion Nebula -- dust. The entire Orion field, located about 1600 light years away, is inundated with intricate and picturesque filaments of dust. Opaque to visible light, dust is created in the outer atmosphere of massive cool stars and expelled by a strong outer wind of particles. The Trapezium and other forming star clusters are embedded in the nebula. The intricate filaments of dust surrounding M42 and M43 appear gray in the above image, while central glowing gas is highlighted in brown and blue. Over the next...

Explanation: If you see a sky like this -- photograph it. A month ago in Iceland, an adventurous photographer (pictured) chanced across a sky full of aurora and did just that. In the foreground lies the stratovolcano Öræfajökull. In the background, among other sky delights, lies the constellation of Orion, visible to the aurora's left. Auroras are sparked by energetic particles from the Sun impacting the magnetic environment around the Earth. Resultant energetic particles such as electrons and protons rain down near the Earth's poles and impact the air. The impacted air molecules obtain excited electrons, and when electrons in...

You've probably heard that Cosmos, the new version starring Neil deGrasse Tyson, is causing waves because it's on FOX, and it actually talks about (gasp!) evolution. But this week, Christians upped the ante on crazy by demanding "equal time" for creationists. You know, because they need things to be "balanced." In his typically incisive style, deGrasse explained one reason why that's a silly idea. “You don’t talk about the spherical Earth with NASA, and then say let’s give equal time to the flat Earthers..."

Since its founding in the 1930s, Alcoholics Anonymous has become part of the fabric of American society. AA and the many 12-step groups it inspired have become the country's go-to solution for addiction in all of its forms. These recovery programs are mandated by drug courts, prescribed by doctors and widely praised by reformed addicts. Dr. Lance Dodes sees a big problem with that. The psychiatrist has spent more than 20 years studying and treating addiction. His latest book on the subject is The Sober Truth: Debunking The Bad Science Behind 12-Step Programs And The Rehab Industry. Dodes tells NPR's...

Good news! As I predicted four years ago, alarmist climate scientist, Michael Mann’s gambit of using the courts to silence debate about his faked “hockey stick” graph is backfiring spectacularly. 17 mainstream media outlets now agree Mann should put up or shut up.

I was making a Costco run with my friend George on Friday, and the subject of the weather came up. It was a nice day, relatively speaking, but Saturday was going to be nicer – nearly 70 degrees. This was a nice change of pace from the polar vortexes and dump trucks full of snow we’ve been hit with here in Maryland for the past three months. Then I looked at my iPhone and noted the forecast calls for another possible large snowstorm Tuesday. George said that seemed a little far away to predict such things with any certainty, and...

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.
