    Explanation: Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1/3 degree wide field of view spans over 30 light-years. The sharp composite, color image, highlights faint details of the region's gas and dust clouds against a backdrop of central Milky Way stars. Stellar winds and energetic light from hot, massive stars formed from M17 stock of cosmic gas and dust have slowly carved away at the remaining interstellar material producing the cavernous appearance and undulating shapes. M17 is also known as...

    CAPE CANAVERAL, Fla. – A white dwarf star in the Constellation Virgo turns out to be a "death star" worthy of "Star Wars." Astronomers announced Wednesday that they have discovered a rocky object coming apart in a death spiral around this distant star. They used NASA's exoplanet-hunting Kepler spacecraft to make the discovery, then followed up with ground observations. "This is something no human has seen before," said Andrew Vanderburg of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the lead author. "We're watching a solar system get destroyed," he said in a statement.

    Explanation:Ne Explanation: The north pole of Saturn's moon Enceladus is unexpectedly fascinating and complex. Previous to the latest flyby of the robotic Cassini spacecraft, the northern region was known mostly for its unusually high abundance of craters. Last week's flyby, however, returned images of unprecedented detail, including the featured image showing the expected craters coupled with an unexpected and circuitous pattern of picturesque cracks and fractures. Broken terrain has been recorded at lower latitudes, with deep canyons dubbed Tiger Stripes near Enceladus' South Pole. The fractures may further indicate global interplay between the surface and potential seas underneath, seas that...

    There are many opinionated people on each side of the political spectrum, including me, but I haven't heard of any conservatives trying to muzzle leftists. Liberals on the other hand? Ha. Man-made global warming liberals ridicule skeptics as corrupt or brain-dead deniers, and their advocate in chief, President Obama, habitually derides conservatives for rejecting his hysterical narrative on climate change. Don't assume they do this solely for political advantage. It can be far more serious than that. A claque of 20 climate scientists, in an open letter, urged Obama and Attorney General Loretta Lynch to use the federal Racketeer Influenced...

    Explanation: What happens when two black holes collide? This extreme scenario likely occurs in the centers of some merging galaxies and multiple star systems. The featured video shows a computer animation of the final stages of such a merger, while highlighting the gravitational lensing effects that would appear on a background starfield. The black regions indicate the event horizons of the dynamic duo, while a surrounding ring of shifting background stars indicates the position of their combined Einstein ring. All background stars not only have images visible outside of this Einstein ring, but also have one or more companion images...

    Explanation: Have you ever seen the Southern Cross? This famous constellation is best seen from Earth's Southern Hemisphere. Captured from Rio de Janeiro, Brazil, the four bright stars that mark the Southern Cross are visible just above the horizon in the featured image. On the left of this constellation, also known as The Crux, is the orange star Gamma Crucis. The band of stars, dust, and gas rising through the middle of the image mosaic is part our Milky Way Galaxy. Just to the right of the Southern Cross is the dark Coal Sack Nebula, and the bright nebula at...
  • Astronomy Picture of the Day -- Mammatus Clouds Over Saskatchewan

    NASA ^ | October 18, 2015 | (see photo credit)
    Explanation: Why is this cloud so bubbly? Normally, cloud bottoms are flat. The flatness is caused by moist warm air that rises and cools and so condenses into water droplets at a specific temperature, which usually corresponds to a very specific height. As water droplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near a thunderstorm. Resulting mammatus clouds can appear especially dramatic if sunlit from the side. These mammatus clouds were...

    Explanation: One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful M81. The grand spiral galaxy can be found toward the northern constellation of the Great Bear (Ursa Major). This superbly detailed image reveals M81's bright yellow nucleus, blue spiral arms, tell tale pinkish star forming regions, 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...

    Explanation: Stars come out as evening twilight fades in this serene skyscape following the Persian proverb "Night hides the world, but reveals a universe." The scene finds the Sun setting over northern Kenya and the night will soon hide the shores of Lake Turkana, home to many Nile crocodiles. The region is also known for its abundance of hominid fossils. On that past November night, a brilliant Venus, then the world's evening star, dominates the starry skies above. But also revealed are faint stars, cosmic dust clouds, and glowing nebulae along the graceful arc of our own Milky Way galaxy....

    The Stream ^ | October 15, 2015 | William M Briggs
    Here’s the breathless headline: “Scientists claim they can change your belief on immigrants and God — with MAGNETS.” Wait. Attitudes toward God and immigrants? Are these a natural pair? The newspaper thought so. They tell of an experiment which “claims to be able to make Christians no longer believe in God and make Britons open their arms to migrants.” How’s it done? “Using a technique called transcranial magnetic stimulation” researchers can “safely shut down certain groups of neurones” in the brain. It seems to have worked. Volunteers were coaxed into having their brains zapped by giant magnets. And, lo! “Belief...
  • Astronomy Picture of the Day -- M16 and the Eagle Nebula

    NASA ^ | October 15, 2015 | (see photo credit)
    Explanation: A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed image of the region includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. Extending from the ridge of bright emission left of center...

    “It was kind of unbelievable that it was real data,” said Yale University astronomer Tabetha Boyajian. “We were scratching our heads. For any idea that came up there was always something that would argue against it.” She was talking to the New Scientist about KIC 8462852, a distant star with a very unusual flickering habit. Something was making the star dim drastically every few years, and she wasn’t sure what. Boyajian wrote up a paper on possible explanations for the star’s bizarre behavior, and it was published recently in the Monthly Notices of the Royal Astronomical Society. But she also...

    Innovative scientists at the Institut Marques in Barcelona, Spain, have made an amazing discovery. Preborn babies can hear and respond to music much sooner than previously believed. “For the first time ever,” it can be scientifically proven that a preborn baby detects and responds to sound at 16 weeks gestation. The Institut Marques reports: “Ultrasound”, the journal of the British Medical Ultrasound Society (BMUS), has published our study entitled “Fetal Facial Expression in Response to Intravaginally Transmitted Music”, an innovative research project on fetal hearing. This report explains that, beginning in week 16 of pregnancy, a response exists to music...

    Explanation: Is there anything interesting to see in the direction opposite the Sun? One night last month, there were quite a few things. First, the red-glowing orb on the lower right of the featured image is the full moon, darkened and reddened because it has entered Earth's shadow. Beyond Earth's cone of darkness are backscattering dust particles orbiting the Sun that standout with a diffuse glow called the gegenschein, visible as a faint band rising from the central horizon and passing behind the Moon. A nearly horizontal stripe of green airglow is also discernable just above the horizon, partly blocked...

    Explanation: Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Of course, the cosmic elephant's trunk is over 20 light-years long. This composite was recorded through narrow band filters that transmit the light from ionized hydrogen, sulfur, and oxygen atoms in the region. The resulting image highlights the bright swept-back ridges that outline pockets of cool interstellar dust and gas. Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars...

    Explanation: Is this galaxy trapped in a web of dust? No -- it is far in the background. However, spiky stars and spooky shapes are abound in this deep cosmic skyscape. Its well-composed field of view covers about a Full Moon on the sky toward the constellation Pegasus. Of course the brighter stars show diffraction spikes, the commonly seen effect of internal supports in reflecting telescopes, and lie well within our own Milky Way galaxy. The faint but pervasive clouds of interstellar dust ride above the galactic plane and dimly reflect the Milky Way's combined starlight. Known as high latitude...
  • Astronomy Picture of the Day -- In the Center of the Trifid Nebula

    NASA ^ | October 11, 2015 | (see photo credit)
    Explanation: Clouds of glowing gas mingle with dust lanes in the Trifid Nebula, a star forming region toward the constellation of the Archer (Sagittarius). In the center, the three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear on the right, while other dark filaments of dust are visible threaded throughout the nebula. A single massive star visible near the center causes much of the Trifid's glow. The Trifid, also known as M20, is only about 300,000 years old, making it among the youngest emission nebulae known. The nebula lies about 9,000...

    Explanation: This cosmic expanse of dust, gas, and stars covers some 6 degrees on the sky in the heroic constellation Perseus. At upper left in the gorgeous skyscape is the intriguing young star cluster IC 348 and neighboring Flying Ghost Nebula. At right, another active star forming region NGC 1333 is connected by dark and dusty tendrils on the outskirts of the giant Perseus Molecular Cloud, about 850 light-years away. Other dusty nebulae are scattered around the field of view, along with the faint reddish glow of hydrogen gas. In fact, the cosmic dust tends to hide the newly formed...
