    NASA ^ | November 26, 2014 | (see photo credit)
    Explanation: A 24 minute sequence from top to bottom, this intriguing series of telescopic frames tracks the occultation of Io by Callisto, two of Jupiter's Galilean moons, from San Pietro Polesine, Italy, planet Earth. A challenging observational project using a small telescope, the two contrasting Jovian worlds are both slightly larger than Earth's Moon. In fact, bright, volcanic Io and dark, cratered Callisto are about 3,640 and 4,820 kilometers in diameter respectively. With Earth itself now crossing near the orbital plane of Jupiter's moons, astronomers are enjoying a season of Galilean moon mutual events ranging from eclipses to occultations. The...

    Explanation: What creature lurks near the red Lagoon nebula? Mars. This gorgeous color deep-sky photograph has captured the red planet passing below two notable nebulae -- cataloged by the 18th century cosmic registrar Charles Messier as M8 and M20. M20 (upper right of center), the Trifid Nebula, presents a striking contrast in red/blue colors and dark dust lanes. Just below and to the left is the expansive, alluring red glow of M8, the Lagoon Nebula. Both nebulae are a few thousand light-years distant. By comparison, temporarily situated below them both, is the dominant "local" celestial beacon Mars. Taken late last...

    NASA ^ | November 24, 2014 | (see photo credit)
    Explanation: What would it look like to fly over Titan? Radar images from NASA's robotic Cassini satellite in orbit around Saturn have been digitally compiled to simulate such a flight. Cassini has swooped past Saturn's cloudiest moon several times since it arrived at the ringed planet in 2004. The virtual flight featured here shows numerous lakes colored black and mountainous terrain colored tan. Surface regions without detailed vertical information appear more flat, while sufficiently mapped regions have their heights digitally stretched. Among the basins visualized is Kraken Mare, Titan's largest lake which spans over 1,000 kilometers long. Titan's lakes are...

    NASA ^ | November 23, 2014 | (see photo credit)
    Explanation: The scene might have been considered serene if it weren't for the tornado. During 2004 in Kansas, storm chaser Eric Nguyen photographed this budding twister in a different light -- the light of a rainbow. Featured here, a white tornado cloud descends from a dark storm cloud. The Sun, peeking through a clear patch of sky to the left, illuminates some buildings in the foreground. Sunlight reflects off raindrops to form a rainbow. By coincidence, the tornado appears to end right over the rainbow. Streaks in the image are hail being swept about by the high swirling winds. Over...

    NASA ^ | November 22, 2014 | (see photo credit)
    Explanation: Solar active region AR2192 was the largest recorded sunspot group of the last 24 years. Before rotating off the Earth-facing side of the Sun at the end of October, it produced a whopping six energetic X-class flares. Its most intense flare was captured on October 24 in this stunning view from the orbiting Solar Dynamics Observatory. The scene is a color combination of images made at three different wavelengths of extreme ultraviolet light; 193 angstroms shown in blue, 171 angstroms in white, and 304 angstroms in red. The emission, from highly ionized Iron and Helium atoms, traces magnetic field...
  • Astronomy Picture of the Day -- M1: The Crab Nebula

    NASA ^ | November 21, 2014 | (see photo credit)
    Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. This sharp, ground-based telescopic view uses narrowband data to track emission from ionized oxygen and hydrogen atoms (in blue and red) and explore the tangled filaments within the still expanding cloud. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning...

    NASA ^ | November 20, 2014 | (see photo credit)
    Explanation: Obscuring the rich starfields of northern Cygnus, dark nebula LDN 988 lies near the center of this cosmic skyscape. Composed with telescope and camera, the scene is some 2 degrees across. That corresponds to 70 light-years at the estimated 2,000 light-year distance of LDN 988. Stars are forming within LDN 988, part of a larger complex of dusty molecular clouds along the plane of our Milky Way galaxy sometimes called the Northern Coalsack. In fact, nebulosities associated with young stars abound in the region, including variable star V1331 Cygni shown in the inset. At the tip of a long...

    NASA ^ | November 19, 2014 | (see photo credit)
    Explanation: One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful M81. This grand spiral galaxy can be found toward the northern constellation of the Great Bear (Ursa Major). This superbly detailed view reveals M81's bright yellow nucleus, blue spiral arms, and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinting at a disorderly past, a remarkable dust lane actually runs straight through the disk, to the left of the galactic center, contrary to M81's other prominent spiral features. The errant dust lane may be the...

    NASA ^ | November 18, 2014 | (see photo credit)
    Explanation: Dusty emission in the Tadpole nebula, IC 410, lies about 12,000 light-years away in the northern constellation Auriga. The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright cluster stars are seen all around the star-forming nebula. Notable near the image center are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation in IC 410, these cosmic tadpole shapes are about 10 light-years long....

    Explanation: What do other star systems look like? To help find out, astronomers are carrying out detailed observations of nearby stars in infrared light to see which have dust disks that might be forming planets. Observations by NASA's Spitzer Space Telescope and ESA's Herschel Space Observatory have found that planetary system HD 95086 has two dust disks: a hot one near the parent star and a cooler one farther out. An artist's illustration of how the system might appear is featured here, including hypothetical planets with large rings that orbit between the disks. The planets may have created the large...

    Medium ^ | 11/20/14 | Ethan Siegel
    When we look out at the Universe, our view is pretty consistently dominated by the stars within our own galaxy. Although we know that many interesting things lie beyond — globular clusters, individual galaxies, and rich clusters and superclusters of galaxies — being in the Milky Way makes it very hard to see a great many of them. This is because our own galaxy, from our vantage point within it, dominates a huge fraction of the sky overhead.

    Renew America ^ | Nov. 20, 2014 | Linda Kimball
    Throughout the de-Christianized West and America neo-pagan and mystical pantheist evolutionary reasoning is taken for granted throughout the college curriculum, just as it is in all aspects of modern thought and experience. It not only undergirds biological and earth sciences, but also Freudian and Jungian psychology, anthropology, law, sociology, politics, economics, the media, arts, medicine, and all other academic---and increasingly seminarian---disciplines as well. The West's amoral transnational elite Gnostics, the "chosen" ones, are particularly enamored of evolutionary reasoning: "Western cultural elites have disregarded God for more than two centuries, but for a while the effects were mostly confined to their...

    WASHINGTON Two of Texas most prominent members of Congress squared off moments ago on the House floor as members prepare to vote on a bill Republicans say will end the EPAs reliance on scientific studies whose data arent fully available to the public. The Secret Science Reform Act of 2014 would require the Environmental Protection Agency to base its rules only on scientific studies whose data can be shared in sufficient details that other researchers can duplicate the research. A vote is expected within the hour, and this post will be updated with its results. The bill, should it...

    The Queen warned last night that focusing too much attention on the Ebola outbreak could lead to an upsurge in other deadly diseases such as malaria. At an event alongside world leaders in the science of infectious diseases yesterday, she asked piercing questions about how the disease ought to be controlled. And the monarch said she worried that Ebola, which has claimed 5,000 lives already, risked overshadowing the risk from other deadlier diseases like malaria, which kills the same number every week.

    The Hill ^ | November 16, 2014 | Timothy Cama
    Senate Republicans appear likely to use their majority status in the next Congress to attack the science behind climate change in an attempt to undercut environmental policies. But some GOP strategists wonder whether such an offensive might backfire. Questioning and attempting to delegitimize climate scientists them has been an oft-used tactic of Sen. Jim Inhofe (R-Okla.), who is poised to reprise his role as chairman of the Environment and Public Works Committee. It was a hallmark of his 2003 to 2007 chairmanship of the panel and the following six years, when he was its ranking member. As...

    NASA ^ | November 16, 2014 | (see photo credit)
    Explanation: Leonids Meteor Shower came to an impressive crescendo in 1999. Observers in Europe saw a sharp peak in the number of meteors visible around 0210 UTC during the early morning hours of November 18. Meteor counts then exceeded 1000 per hour - the minimum needed to define a true meteor storm. At other times and from other locations around the world, observers typically reported respectable rates of between 30 and 100 meteors per hour. This photograph is a 20-minute exposure ending just before the main Leonids peak began. Visible are at least five Leonid meteors streaking high above the...

    God Exists – I Can Prove It! Pt. 2 In my last blog post, we pretty much nailed the idea that the universe has a beginning. And if it has a beginning, it must have a Beginner who is omnipotent.In a recent discussion with an atheist, however, I got an interesting retort at this point:Just because there was a “beginning” of this universe of ours, does not mean there could not have been other universes before ours. Moreover, how do you know there are not parallel universes to ours and that ours came from one or more of them? Or,...

    Explanation: Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of this composite image. Red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms. Ultraviolet radiation from young, energetic stars at the edge of the Cygnus...

    Explanation: The Rosetta Mission lander is safely on a comet. One of Philae's feet appears at the bottom left of this spectacular image of the surface of C67/P Churyumov-Gerasimenko. Still a happy lander, Philae bounced twice before settling and returning images from the surface, traveling a kilometer or so after initially touching at the targeted site Agilkia. A surface panorama suggests that the lander has come to rest tilted and near a shadowing wall, with its solar panels getting less illumination that hoped. Philae's science instruments are working as planned and data is being relayed during communications windows, when the...

    God Exists – I Can Prove It! Pt. 1 As a Catholic apologist, I hear way too many sad stories from parents telling of children gone astray. Little Johnny (or little Janey) went off to college and got ”enlightened” as to the truth about God and science. The refrain is repeated: “Science has disproved the existence of God, mom and dad. All that we know or can know exists is what we see in the material universe and that can be scientifically proven. Any notion of ‘spirit’ or a ‘supreme being’ is based purely on emotion and wishful thinking.”The parents are always devastated and often...

    Explanation: Yesterday, the first soft landing on a comet took place some 500 million kilometers from planet Earth as the Rosetta mission lander Philae settled on the nucleus of C67/P Churyumov-Gerasimenko. The landing site, dubbed Agilkia, is located near the center of this remarkable image snapped by Philae's ROLIS (ROsetta Lander Imaging System) camera. Taken from a distance of about 3 kilometers the image has a resolution of about 3 meters per pixel at the surface. After Philae's release from the orbiter, its seven-hour long descent was made without propulsion or guidance. Following its descent the lander is in place,...

    Explanation: Today humanity will make its first attempt to land a probe on the nucleus of a comet. As the day progresses, the Philae (fee-LAY) lander will separate from the Rosetta spacecraft and head down to the surface of Comet 67P/ChuryumovGerasimenko. Since the texture of the comet's surface is unknown and its surface gravity is surely low, Philae will then attempt to harpoon itself down, something that has never been done before. Featured here is an artist's illustration of dishwasher-sized Philae as it might look on Comet ChuryumovGerasimenko's surface, along with explanation balloons detailing onboard scientific instruments.

    Explanation: The constellation of Orion holds much more than three stars in a row. A deep exposure shows everything from dark nebula to star clusters, all embedded in an extended patch of gaseous wisps in the greater Orion Molecular Cloud Complex. The brightest three stars on the far left are indeed the famous three stars that make up the belt of Orion. Just below Alnitak, the lowest of the three belt stars, is the Flame Nebula, glowing with excited hydrogen gas and immersed in filaments of dark brown dust. Below and left of the frame center and just to the...

    Explanation: Why does this giant disk have gaps? The exciting and probable answer is: planets. A mystery is how planets massive enough to create these gaps formed so quickly, since the HL Tauri star system is only about one million years old. The picture on which the gaps were discovered was taken with the new Atacama Large Millimeter Array (ALMA) of telescopes in Chile. ALMA imaged the protoplanetary disk, which spans about 1,500 light-minutes across, in unprecedented detail, resolving features as small as 40 light minutes. The low energy light used by ALMA was also able to peer through an...

    In high school biology, we are taught that there are three types of life: eukaryotes (that's us, and most everything else we often think of as life), bacteria, and archaea (extremophiles and other very primitive life forms). But some scientists are pretty sure that there are entirely different, undiscovered lifeforms that could be prevalent on Earth, and they remain undescribed because we're not good at looking for them. In a new paper published in Science, Tanja Woyke and Edward Rubin of the Department of Energy's Joint Genome Institute note that "there are reasons to believe that current approaches [to discovering...

    Explanation: To some, it may look like a cat's eye. The alluring Cat's Eye nebula, however, lies three thousand light-years from Earth across interstellar space. A classic planetary nebula, the Cat's Eye (NGC 6543) represents a final, brief yet glorious phase in the life of a sun-like star. This nebula's dying central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layers in a series of regular convulsions. But the formation of the beautiful, more complex inner structures is not well understood. Seen so clearly in this digitally sharpened Hubble Space Telescope image,...

    Explanation: NGC 660 is featured in this cosmic snapshot, a sharp composite of broad and narrow band filter image data from the Gemini North telescope on Mauna Kea. Over 20 million light-years away and swimming within the boundaries of the constellation Pisces, NGC 660's peculiar appearance marks it as a polar ring galaxy. A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting in rings nearly perpendicular to the plane of the galactic disk. The bizarre-looking configuration could have been caused by the chance capture of material from a passing galaxy by a...

    Explanation: This cylindrical projection global map is one of six new color maps of Saturn's midsized icy moons, constructed using 10 years of image data from the Cassini spacecraft. Discovered by Cassini (the astronomer) in 1684, Dione is about 1,120 kilometers across. Based on data extending from infrared to ultraviolet, the full resolution of this latest space-age map is 250 meters per pixel. The remarkable brightness difference between the tidally locked moon's lighter leading hemisphere (right) and darker trailing hemisphere clearly stands out. Like other Saturn moons orbiting within the broad E-ring, Dione's leading hemisphere is kept shiny as it...

    Explanation: This colorful skyscape features the dusty Sharpless catalog emission region Sh2-155, the Cave Nebula. In the composite image, data taken through narrowband filters tracks the glow of ionized sulfur, hydrogen, and oxygen atoms in red, green, and blue hues. About 2,400 light-years away, the scene lies along the plane of our Milky Way Galaxy toward the royal northern constellation of Cepheus. Astronomical explorations of the region reveal that it has formed at the boundary of the massive Cepheus B molecular cloud and the hot, young stars of the Cepheus OB 3 association.

    Explanation: Why is there a bright line on the sky? What is pictured above is actually a disk galaxy being seen almost perfectly edge on. The image from the Hubble Space Telescope is a spectacular visual reminder of just how thin disk galaxies can be. NGC 4762, a galaxy in the nearby Virgo Cluster of Galaxies, is so thin that it is actually difficult to determine what type of disk galaxy it is. Its lack of a visible dust lane indicates that it is a low-dust lenticular galaxy, although it is still possible that a view from on top would...

    Explanation: Described at times as a big blue marble, from some vantage points Earth looks more like a small blue marble. Such was the case in this iconic image of the Earth and Moon system taken by the Chang'e 5-T1 mission last week. The Moon appears larger than the Earth because it was much closer to the spacecraft's camera. Displaying much of a surface usually hidden from Earth, the Moon appears dark and gray when compared to the more reflective and colorful planet that it orbits. The robotic Chang'e 5-T1 spacecraft, predominantly on an engineering test mission, rounded the Moon...

    Explanation: When orbiting Saturn, be sure to watch for breathtaking superpositions of moons and rings. One such picturesque vista was visible recently to the robot Cassini spacecraft now orbiting Saturn. In 2006 April, Cassini captured Saturn's A and F rings stretching in front of cloud-shrouded Titan. Near the rings and appearing just above Titan was Epimetheus, a moon which orbits just outside the F ring. The dark space in the A ring is called the Encke Gap, although several thin knotted ringlets and even the small moon Pan orbit there.

Reports of the invasion were revealed to be part of a Halloween radio drama, the now famous broadcast based on H.G. Wells' scifi novel War of the Worlds. On Mars October 20, 2014 was calm too, the day after its close encounter with Comet Siding Spring. Not a hoax, this comet really did come within 86,700 miles or so of Mars, about 1/3 the Earth-Moon distance. Earth's spacecraft and rovers in Mars orbit and on the surface reported no ill effects though, and had...

    Explanation: A mysterious formation known as Devils Tower rises into the dark above northeastern Wyoming's prairie landscape in this 16 frame panoramic view. Seen against the night sky's thin, pale clouds and eerie green airglow, star clusters and nebulae of the Milky Way arc toward the galaxy's central realm at right. Of course the scene contains the Milky Way's own haunting and grisly visages of halloween, including ghosts, a flaming skull, a glowing eye and a witch's broom. To find them, slide your cursor over the picture or just follow this link, if you dare. And have a safe and...

    Explanation: Frightening forms and scary faces are a mark of the Halloween season. They also haunt this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky in the constellation Cygnus, this portion of the eastern Veil spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil's estimated distance, a reassuring 1,400 light-years from planet Earth. In...

    Explanation: Sometimes your eclipse viewing goes bad in an interesting way. While watching and photographing last Thursday's partial solar eclipse, a popular astronomy blogger suffered through long periods of clouds blocking the Sun. Unexpectedly, however, a nearby cloud began to show a rare effect: iridescence. Frequently part of a more familiar solar corona effect, iridescence is the diffraction of sunlight around a thin screen of nearly uniformly-sized water droplets. Different colors of the sunlight become deflected by slightly different angles and so come to the observer from slightly different directions. This display, featured here, was quite bright and exhibited an...

    Explanation: Why would Mars appear to move backwards? Most of the time, the apparent motion of Mars in Earth's sky is in one direction, slow but steady in front of the far distant stars. About every two years, however, the Earth passes Mars as they orbit around the Sun. During the most recent such pass starting late last year, Mars as usual, loomed large and bright. Also during this time, Mars appeared to move backwards in the sky, a phenomenon called retrograde motion. Featured here is a series of images digitally stacked so that all of the stars coincide. Here,...

    Explanation: What's that in front of the Sun? The closest object is an airplane, visible just below the Sun's center and caught purely by chance. Next out are numerous clouds in Earth's atmosphere, creating a series of darkened horizontal streaks. Farther out is Earth's Moon, seen as the large dark circular bite on the upper right. Just above the airplane and just below the Sun's surface are sunspots. The main sunspot group captured here, AR 2192, is one of the largest ever recorded and has been crackling and bursting with flares since it came around the edge of the Sun...

    How Electric Superchargers Went from Fantasy to Feasibility October 30, 2014 at 11:30:00 AM by David Gluckman | 0 Comments   Comments 0 Share   (Photo Credit: Chris Philpot) Until recently, electric superchargers might as well have been perpetual motion machines, for sale at the same places as gasoline magnet ionizers and other snake-oil. Power for an electric compressor has to come from somewhere, and e-turbos were a kind of get-power-quick scheme that ultimately left you poorer. That’s starting to change. Step one, as it usually does, involved motorsports. The current crop of Formula 1 cars and Audi’s latest R18 use...

    As you read this, your neurons are firing that brain activity can now be decoded to reveal the silent words in your head TALKING to yourself used to be a strictly private pastime. That's no longer the case researchers have eavesdropped on our internal monologue for the first time. The achievement is a step towards helping people who cannot physically speak communicate with the outside world. "If you're reading text in a newspaper or a book, you hear a voice in your own head," says Brian Pasley at the University of California, Berkeley. "We're trying to decode the...

    On Monday, Centers for Disease Control and Prevention head Thomas Frieden announced a new policy on health care workers returning from Ebola-plagued West Africa. Parroting President Obamas Saturday radio address, Frieden cautioned that Americans must be guided by the science, not fear. Sorry. The Obama administrations halfway approach is based on political correctness, not science. And it is a gamble. According to Frieden, about five health care workers fly back from West Africa to the U.S. every day, landing at Chicago, Newark, Atlanta, New Yorks JFK or Dulles outside of Washington, D.C. For months, the CDC did almost nothing to...

    The Hill ^ | October 27, 2014 | Laura Barron-Lopez
    Environmental groups are on track to spend more than $85 million on key races this year, more than ever before, according to an internal memo. The record spending comes as green groups are worried about the fate of the Senate and the future of President Obamas climate agenda, which they say is crucial to helping the U.S. and other nations curb greenhouse gas emissions and stave off disastrous climate impacts. A memo circulated among five of the nations top environmental organizations, and provided to The Hill, summarizes in detail the plan hatched by the groups to put climate change on...
  • Sarah Palin Compares Climate Change 'Hysteria' To Eugenics

    Sarah Palin is once again brushing off global warming as "junk science," comparing warnings about the threat of climate change to the eugenics movement of the early 20th century. Last week, the former Alaska governor and 2008 Republican vice presidential candidate recorded a video for the Sarah Palin Channel dismissing the "con job" of man-made climate change. "I'm not a denier. I don't doubt that climate change exists," Palin says in the video. "No one has proven that these changes are caused by anything done by human beings via greenhouse gases. There's no convincing scientific evidence for man-made climate change....

    Despite President Barack Obama's appointment of an "Ebola czar" to oversee and coordinate the U.S. response to the deadly outbreak, some politicians and even an Army general are going against White House guidance, submitting people to the kinds of quarantines that scientists warn could make containing the epidemic more difficult. Obama said any measures involving health care workers "should be crafted so as not to unnecessarily discourage those workers from serving." U.S. ambassador to the United Nations Samantha Power, now in West Africa, said any returning workers should be "treated like conquering heroes and not stigmatized for the tremendous work...
