    Explanation: You may have heard of the Seven Sisters in the sky, but have you heard about the Seven Strong Men on the ground? Located just west of the Ural Mountains, the unusual Manpupuner rock formations are one of the Seven Wonders of Russia. How these ancient 40-meter high pillars formed is yet unknown. The persistent photographer of this featured image battled rough terrain and uncooperative weather to capture these rugged stone towers in winter at night, being finally successful in February of last year. Utilizing the camera's time delay feature, the photographer holds a flashlight in the foreground near...

    Explanation: Ten Earths could easily fit in the "claw" of this seemingly solar monster. The monster, actually a huge eruptive prominence, is seen moving out from our Sun in this condensed half-hour time-lapse sequence. This large prominence, though, is significant not only for its size, but its shape. The twisted figure eight shape indicates that a complex magnetic field threads through the emerging solar particles. Differential rotation of gas just inside the surface of the Sun might help account for the surface explosion. The five frame sequence was taken in early 2000 by the Sun-orbiting SOHO satellite. Although large prominences...

    Explanation: Celebrating astronomy in this International Year of Light, the detailed image reveals spectacular active galaxy Cygnus A in light across the electromagnetic spectrum. Incorporating X-ray data ( blue) from the orbiting Chandra Observatory, Cygnus A is seen to be a prodigious source of high energy x-rays. But it is actually more famous at the low energy end of the electromagnetic spectrum. One of the brightest celestial sources visible to radio telescopes, at 600 million light-years distant Cygnus A is the closest powerful radio galaxy. Radio emission ( red) extends to either side along the same axis for nearly 300,000...

    Explanation: Some prefer windows, and these are the best available on board the International Space Station. Taken on January 4, this snapshot from inside the station's large, seven-window Cupola module also shows off a workstation for controlling Canadarm2. Used to grapple visiting cargo vehicles and assist astronauts during spacewalks, the robotic arm is just outside the window at the right. The Cupola itself is attached to the Earth-facing or nadir port of the station's Tranquility module, offering dynamic panoramas of our fair planet. Seen from the station's 90 minute long, 400 kilometer high orbit, Earth's bright limb is in view...

    Explanation: Blasting skyward an Atlas V rocket carrying a U.S. Navy satellite pierces a cloud bank in this starry night scene captured on January 20. On its way to orbit from Space Launch Complex 41, Cape Canaveral Air Force Station, planet Earth, the rocket streaks past brightest star Sirius, as seen from a dark beach at Canaveral National Seashore. Above the alpha star of Canis Major, Orion the Hunter strikes a pose familiar to northern winter skygazers. Above Orion is the V-shaped Hyades star cluster, head of Taurus the Bull, and farther still above Taurus it's easy to spot the...
  • Astronomy Picture of the Day -- The Complex Ion Tail of Comet Lovejoy

    NASA ^ | January 21, 2015 | (see photo credit)
    Explanation: What causes the structure in Comet Lovejoy's tail? Comet C/2014 Q2 (Lovejoy), which is currently at naked-eye brightness and near its brightest, has been showing an exquisitely detailed ion tail. As the name implies, the ion tail is made of ionized gas -- gas energized by ultraviolet light from the Sun and pushed outward by the solar wind. The solar wind is quite structured and sculpted by the Sun's complex and ever changing magnetic field. The effect of the variable solar wind combined with different gas jets venting from the comet's nucleus accounts for the tail's complex structure. Following...
  • Galileo's notebooks may reveal secrets of new planet

    University of Melbourne ^ | Jul 9, 2009 | Unknown
    Galileo knew he had discovered a new planet in 1613, 234 years before its official discovery date, according to a new theory by a University of Melbourne physicist. Professor David Jamieson, Head of the School of Physics, is investigating the notebooks of Galileo from 400 years ago and believes that buried in the notations is the evidence that he discovered a new planet that we now know as Neptune. A hypothesis of how to look for this evidence has been published in the journal Australian Physics and was presented at the first lecture in the 2009 July Lectures in Physics...

    Explanation: It is the largest asteroid in the asteroid belt -- what secrets does it hold? To find out, NASA has sent the robotic Dawn spacecraft to explore and map this cryptic 1,000-kilometer wide world: Ceres. Orbiting between Mars and Jupiter, Ceres is officially categorized as a dwarf planet but has never been imaged in detail. Featured here is a 20-frame video taken a week ago of Dawn's approach that now rivals even the best images of Ceres ever taken by the Hubble Space Telescope. The video shows enough surface definition to discern its 9-hour rotation period. On target to...

    Explanation: The Great Nebula in Orion is an intriguing place. Visible to the unaided eye, it appears as a small fuzzy patch in the constellation of Orion. But this image, an illusory-color four-panel mosaic taken in different bands of infrared light with the Earth orbiting WISE observatory, shows the Orion Nebula to be a bustling neighborhood or recently formed stars, hot gas, and dark dust. The power behind much of the Orion Nebula (M42) is the stars of the Trapezium star cluster, seen near the center of the above wide field image. The orange glow surrounding the bright stars pictured...

    Forbes ^ | 1/18/2015 @ 12:00PM | Eric Mack
    The Kepler space telescope has spotted over 1,000 exoplanets beyond our solar system, and its latest finds are three almost Earth-sized planets, including one in the habitable zone circling the star EPIC 201367075, just 150 light years from Earth. In the cosmic sense, that’s right around the block, making it one of the 10 closest known stars with observed planets in its gravitational hold. Of course, such distances in the cosmic sense also would take many generations to traverse, so don’t invest in real estate there just yet. Still, the relative closeness of this “EPIC” star and its planets provides...

    On January 16 The New York Times reported the lies NASA keeps telling about global warming with an article titled “2014 Breaks Heat Record, Challenging Global Warming Skeptics.” We have reached the point where neither a famed government agency nor a famed daily newspaper can be believed simply because both are lying to advance the greatest hoax of the modern era. Remember that 2014 started off with something called a “polar vortex” to describe the incredibly cold weather being experienced and remember, too, that we were being told that it was evidence of global warming! That’s how stupid the “Warmists”...

    Explanation: What's happening at the center of our Milky Way Galaxy? To help find out, the orbiting Hubble and Spitzer space telescopes have combined their efforts to survey the region in unprecedented detail in infrared light. Milky Way's center because visible light is more greatly obscured by dust. The above image encompasses over 2,000 images from the Hubble Space Telescope's NICMOS taken in 2008. The image spans 300 by 115 light years with such high resolution that structures only 20 times the size of our own Solar System are discernable. Clouds of glowing gas and dark dust as well as...

    Team calls for more scepticism in marine research.___ The state of the world's seas is often painted as verging on catastrophe. But although some challenges are very real, others have been vastly overstated, researchers claim in a review paper. The team writes that scientists, journals and the media have fallen into a mode of groupthink that can damage the credibility of the ocean sciences. The controversial study exposes fault lines in the marine-science community. Carlos Duarte, a marine biologist at the University of Western Australia in Perth, and his colleagues say that gloomy media reports about ocean issues such as...

    The Hill ^ | 1/16/15 | Jesse Byrnes
    Secretary of State John Kerry on Friday called for "ambitious, concrete action" to combat climate change after a government agency released new data about global temperatures. "What’s surprising is that anyone is surprised that 2014 was the hottest year on record. The science has been screaming at us for a long, long time," Kerry said Friday in a statement released by the State Department. Kerry said historic temperatures, greenhouse gas emissions and extreme weathers events like torrential rain and droughts "are having devastating economic, security and health impacts across the planet." His comments were in response to a new report...

    Explanation: Sweeping north in planet Earth's sky, Comet Lovejoy's greenish coma and blue tinted ion tail stretched across this field of stars in the constellation Taurus on January 13. The inset at the upper left shows the 1/2 degree angular size of the full moon for scale. So Lovejoy's coma appears only a little smaller (but much fainter) than a full moon on the sky, and its tail is visible for over 4 degrees across the frame. That corresponds to over 5 million kilometers at the comet's estimated distance of 75 million kilometers from Earth. Blown by the solar wind,...

    Britain's Beagle 2 lander has finally been spotted, 12 years after it went missing while trying to land on the surface of Mars History books will need to be rewritten after scientists announced today that Beagle 2 has been finally been found on Mars, 12 years after it vanished without trace. The beleaguered spacecraft, which has become a byword for mission failure, was spotted by scientists operating the HiRise camera on NASA’s Mars Reconnaissance Orbiter (MRO). It was discovered just 5km from its original touchdown site in the Isidis Planitia basin. And it appears that just one faulty motor was...

    Explanation: Delivered by Saturn-bound Cassini, ESA's Huygens probe touched down on the ringed planet's largest moon Titan, ten years ago on January 14, 2005. These panels show fisheye images made during its slow descent by parachute through Titan's dense atmosphere. Taken by the probe's descent imager/spectral radiometer instrument they range in altitude from 6 kilometers (upper left) to 0.2 kilometers (lower right) above the moon's surprisingly Earth-like surface of dark channels, floodplains, and bright ridges. But at temperatures near -290 degrees C, the liquids flowing across Titan's surface are methane and ethane, hydrocarbons rather than water. After making the most...

    Explanation: Inner planets Venus and Mercury can never wander far from the Sun in Earth's sky. This week you've probably seen them both gathered near the western horizon just after sunset, a close conjunction of bright celestial beacons in the fading twilight. The pair are framed in this early evening skyview captured on January 13 from the ruins of Szarvasko Castle in northwestern Hungary. Above the silhouette of the landscape's prominent volcanic hill Venus is much the brighter, separated from Mercury by little more than the width of two Full Moons. On Friday, planet Earth's early morning risers will also...

    Break Point ^ | 01/14/2015 | Eric Metaxas
    I’m not a scientist, and I don’t play one on TV. But I can examine scientific evidence and ask the question, “How is life possible?” This past Christmas, the Wall Street Journal ran an essay of mine entitled “Science Increasingly Makes the Case for God.” The content will be familiar to those who have read my latest book, “Miracles,” or heard me talk about it here at BreakPoint. I noted that the initial euphoria over the possibility that there were a septillion -- that’s one followed by 24 zeros -- planets capable of supporting life in the universe was followed...
