Discovery Channel Large Asteroid Impact Simulation

● Discovery Channel - Large Asteroid Impact Simulation (2008).

Earth was born as a result of repeated asteroid collisions, the moon was created by a single giant impact event. Then, Earth's size attracted huge meteorites, which slammed into it, causing super-high-temperature rock vapour to cover the entire surface and evaporate all ocean water. The earliest life-forms survived such infernal events by escaping deep into the ground, miraculously emerging again and again. The Earth has gone through innumerable catastrophic events, and life has survived by acquiring new abilities to live through each crisis. Humans are part of the grand history of life's evolution, which has been closely intertwined with repeated cataclysmic events.

Learn what would happen if an asteroid hit the Earth with this detailed "Large Asteroid Impact Simulation".
An asteroid with a diameter of 500 km. Destination: The Pacific Ocean. The impact peels the 10 km crust off the surface. The shockwave travels at hypersonic speeds. Debris is blasted across into low Earth orbit, and returns to destroy the surface of the Earth. The firestorm encircles the Earth, vaporizing all life in its way. Within one day, the surface of the Earth is uninhabitable. The evidence shows that this has happened at least six times in Earth's history.

● Discovery Channel - Simulazione di impatto con un asteroide di grandi dimensioni (2008).

La Terra è nata a seguito di ripetute collisioni di asteroidi, la luna è stata creata da un singolo impatto gigantesco. Poi, le dimensioni della Terra hanno attratto enormi meteoriti, che si sono schiantate su di essa, causando vapori di roccia ad altissima temperatura che hanno ricoperto l'intera superficie e fatto evaporare tutta l'acqua dell'oceano. Le prime forme di vita sono sopravvissute a tali eventi infernali fuggendo in profondità nel terreno, emergendo miracolosamente ancora e ancora. La Terra è passata attraverso innumerevoli eventi catastrofici, e la vita è sopravvissuta attraverso l'acquisizione di nuove capacità per vivere attraverso ogni crisi. Gli esseri umani sono parte della grande storia dell'evoluzione della vita, che è stata strettamente intrecciata con ripetuti eventi catastrofici.

FANTASTIC PHOTOGRAPHY Milky Way over the Pinnacles in Australia

Milky Way over the Pinnacles in Australia:

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2016 February 17



See Explanation. Clicking on the picture will download the highest resolution version available.
Explanation: What strange world is this? Earth. In the foreground of the featured image are the Pinnacles, unusual rock spires in Nambung National Park in Western Australia. Made of ancient sea shells (limestone), how these human-sized picturesque spires formed remains unknown. In the background, just past the end of the central Pinnacle, is a bright crescent Moon. The eerie glow around the Moon is mostly zodiacal light, sunlight reflected by dust grains orbiting between the planets in the Solar System. Arching across the top is the central band of our Milky Way Galaxy. Many famous stars and nebula are also visible in the background night sky. The featured 29-panel panorama was taken and composed last September after detailed planning that involved the Moon, the rock spires, and their corresponding shadows. Even so, the strong zodiacal light was a pleasant surprise.

The Rise and Fall of Supernova 2015F

The Rise and Fall of Supernova 2015F:

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2016 February 9
Explanation: Sit back and watch a star explode. The actual supernova occurred back when dinosaurs roamed the Earth, but images of the spectacular event began arriving last year. Supernova 2015F was discovered in nearby spiral galaxy NGC 2442 by Berto Monard in 2015 March and was unusually bright -- enough to be seen with only a small telescope. The pattern of brightness variation indicated a Type Ia supernova -- a type of stellar explosion that results when an Earth-size white dwarf gains so much mass that its core crosses the threshold of nuclear fusion, possibly caused by a lower mass white-dwarf companion spiraling into it. Finding and tracking Type Ia supernovae are particularly important because their intrinsic brightness can be calibrated, making their apparent brightness a good measure of their distance -- and hence useful toward calibrating the distance scale of the entire universe. The featured video tracked the stellar disruption from before explosion images arrived, as it brightened, and for several months as the fission-powered supernova glow faded. The remnants of SN2015F are now too dim to see without a large telescope. Just yesterday, however, the night sky lit up once again, this time with an even brighter supernova in an even closer galaxy: Centaurus A.

Explanation: Large galaxies grow by eating small ones. Even our own galaxy practices galactic cannibalism, absorbing small galaxies that get too close and are captured by the Milky Way's gravity. In fact, the practice is common in the universe and illustrated by this striking pair of interacting galaxies from the banks of the southern constellation Eridanus, The River. Located over 50 million light years away, the large, distorted spiral NGC 1532 is seen locked in a gravitational struggle with dwarf galaxy NGC 1531 (right of center), a struggle the smaller galaxy will eventually lose. Seen edge-on, spiral NGC 1532 spans about 100,000 light-years. Nicely detailed in this sharp image, the NGC 1532/1531 pair is thought to be similar to the well-studied system of face-on spiral and small companion known as M51.

LIGO Detects Gravitational Waves from Merging Black Holes

LIGO Detects Gravitational Waves from Merging Black Holes:

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2016 February 11


See Explanation. Clicking on the picture will download the highest resolution version available.
Explanation: Gravitational radiation has been directly detected. The first-ever detection was made by both facilities of the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Washington and Louisiana simultaneously last September. After numerous consistency checks, the resulting 5-sigma discovery was published today. The measured gravitational waves match those expected from two large black holes merging after a death spiral in a distant galaxy, with the resulting new black hole momentarily vibrating in a rapid ringdown. A phenomenon predicted by Einstein, the historic discovery confirms a cornerstone of humanity's understanding of gravity and basic physics. It is also the most direct detection of black holes ever. The featured illustration depicts the two merging black holes with the signal strength of the two detectors over 0.3 seconds superimposed across the bottom. Expected future detections by Advanced LIGO and other gravitational wave detectors may not only confirm the spectacular nature of this measurement but hold tremendous promise of giving humanity a new way to see and explore our universe.

VIDEO Two Black Holes Merge

Two Black Holes Merge:

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2016 February 12
Explanation: Just press play to watch two black holes merge. Inspired by the first direct detection of gravitational waves by LIGO, this simulation video plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage the black holes are posed in front of stars, gas, and dust. Their extreme gravity lenses the light from behind them into Einstein rings as they spiral closer and finally merge into one. The otherwise invisible gravitational waves generated as the massive objects rapidly coalesce cause the visible image to ripple and slosh both inside and outside the Einstein rings even after the black holes have merged. Dubbed GW150914, the gravitational waves detected by LIGO are consistent with the merger of 36 and 29 solar mass black holes at a distance of 1.3 billion light-years. The final, single black hole has 62 times the mass of the Sun, with the remaining 3 solar masses converted into energy in gravitational waves.

See Explanation. Clicking on the picture will download the highest resolution version available.
Explanation: Massive star IRS 4 is beginning to spread its wings. Born only about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), featured here. A large disk of dust and gas orbiting Infrared Source 4 (IRS 4), visible in brown near the image center, gives the nebula an hourglass or butterfly shape. S106 gas near IRS 4 acts as an emission nebula as it emits light after being ionized, while dust far from IRS 4 reflects light from the central star and so acts as a reflection nebula. Detailed inspection of a recent infrared image of S106 reveal hundreds of low-mass brown dwarf stars lurking in the nebula's gas. S106 spans about 2 light-years and lies about 2000 light-years away toward the constellation of the Swan (Cygnus).

Mary Fallin dips into emergency fund for earthquake research Related: Wastewater disposal volumes rose 81 percent in six years as earthquakes rumbled more frequently The third-largest earthquake in recorded state history rocked parts of western Oklahoma on Saturday morning near the site of other large, recent temblors. The quake registered a magnitude of 5.1 and was recorded northwest of Fairview at 11:07 a.m., according to preliminary estimates from the U.S. Geological Survey. A 3.9 aftershock followed about 10 minutes after the earthquake, according to the USGS. At 5.1, the temblor will be the state’s third-largest earthquake, according to Oklahoma Geological Survey data. The state’s largest earthquake is a 5.6 recorded out of Prague in 2011. The second was a 5.5 recorded near El Reno in 1952. Before Saturday, those two were the only quakes in state history to exceed a 5.0 magnitude. Saturday’s quake surpassed a 4.8 recorded on Jan. 6 for this year’s largest earthquake. Both the 4.8 and Saturday’s 5.1 were centered near Fairview, according to USGS data. Officials were preparing a further response to the state’s earthquake outbreak even before Saturday’s temblors. The Oil and Gas Conservation Division of the Oklahoma Corporation Commission on Tuesday is scheduled to release details of a large regional plan to address the continuing earthquakes in such areas as Fairview, Cherokee, Medford and elsewhere in the western region, according to a release from the commission. “We have long been worried about the earthquakes in that area, in the sharp rise in seismicity,” OCC spokesman Matt Skinner said. “Obviously, ... it takes time to put together the plan.” The plan involves a large-scale regional reduction in oil and gas wastewater disposal for an approximately 5,000-square-mile area in western Oklahoma and will affect more than 200 Arbuckle disposal wells, the release states. “In this case, there is nothing more to be done — we have a plan in place to deal with this,” Skinner said. “To be clear, we’ll release the specific details on Tuesday publicly, but the plan itself is already in place and the operators started to be notified on Thursday of this week.” How the commission has responded to seismic events has evolved over the years. Two years ago, for example, commissioners took a well-by-well approach, Skinner said. “As the data becomes available to the researchers we’re working with, we’re putting together these plans, and these plans will continue until we obviously have brought the overall rate down,” he said. “As the knowledge grows, so will the plan.” Researchers agree that disposal wells injecting into the Arbuckle formation pose the highest potential risk for causing damaging earthquakes in Oklahoma. The action taken by the commission is not a response to Saturday’s event specifically, but to the overall increase in earthquakes in the region, Skinner said. The whole region is the newest area of production and has been steadily growing. “This latest event simply underscores — it’s like the big bold underline — how important it is to put this plan in place,” Skinner said. Before Saturday, Oklahoma had been shaken by seven earthquakes of at least 4.0 magnitude in 2016. Those quakes were all recorded within the first eight days of January. The strongest of those — the 4.8 on Jan. 6 — was among a swam of 32 earthquakes recorded over a period of about 24 hours. Through Friday evening, Oklahoma had recorded 133 quakes this year that measured at least 3.0, according to the Oklahoma Geological Survey. As of Saturday evening, the USGS had recorded more than a dozen earthquakes with a magnitude of 2.5 or greater in Oklahoma, including the magnitude-5.1 temblor. All but three were in the Fairview area.

Light Pillars over Alaska:

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2016 February 8



See Explanation. Clicking on the picture will download the highest resolution version available.
Explanation: What's happening behind those houses? Pictured here are not auroras but nearby light pillars, a nearby phenomenon that can appear as a distant one. In most places on Earth, a lucky viewer can see a Sun-pillar, a column of light appearing to extend up from the Sun caused by flat fluttering ice-crystals reflecting sunlight from the upper atmosphere. Usually these ice crystals evaporate before reaching the ground. During freezing temperatures, however, flat fluttering ice crystals may form near the ground in a form of light snow, sometimes known as a crystal fog. These ice crystals may then reflect ground lights in columns not unlike a Sun-pillar. The featured image was taken in Fort Wainwright near Fairbanks in central Alaska.

Image Credit & Copyright: CHART32 Team, Processing - Johannes Schedler
Explanation: Massive stars lie within NGC 6357, an expansive emission nebula complex some 6,500 light-years away toward the tail of the constellation Scorpius. In fact, positioned near center in this ground-based close-up of NGC 6357, star cluster Pismis 24 includes some of the most massive stars known in the galaxy, stars with nearly 100 times the mass of the Sun. The nebula's bright central region also contains dusty pillars of molecular gas, likely hiding massive protostars from the prying eyes of optical instruments. Intricate shapes in the nebula are carved as interstellar winds and energetic radiation from the young and newly forming massive stars clear out the natal gas and dust and power the nebular glow. Enhancing the nebula's cavernous appearance, narrowband image data was included in this composite color image in a Hubble palette scheme. Emission from sulfur, hydrogen, and oxygen atoms is shown in red green and blue hues. The alluring telescopic view spans about 50 light-years at the estimated distance of NGC 6357.

Galaxy Wars: M81 versus M82
Image Credit & Copyright: André van der Hoeven, Neil Fleming & Michael Van Doorn
Explanation: In the lower left corner, surrounded by blue spiral arms, is spiral galaxy M81. In the upper right corner, marked by red gas and dust clouds, is irregular galaxy M82. This stunning vista shows these two mammoth galaxies locked in gravitational combat, as they have been for the past billion years. The gravity from each galaxy dramatically affects the other during each hundred million-year pass. Last go-round, M82's gravity likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. But M81 left M82 with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays. This big battle is seen from Earth through the faint glow of an Integrated Flux Nebula, a little studied complex of diffuse gas and dust clouds in our Milky Way Galaxy. In a few billion years only one galaxy will remain.

MWC 922: The Red Square Nebula

MWC 922: The Red Square Nebula:

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2016 January 31



See Explanation. Clicking on the picture will download the highest resolution version available.
Explanation: What could cause a nebula to appear square? No one is quite sure. The hot star system known as MWC 922, however, appears to be embedded in a nebula with just such a shape. The featured image combines infrared exposures from the Hale Telescope on Mt. Palomar in California, and the Keck-2 Telescope on Mauna Kea in Hawaii. A leading progenitor hypothesis for the square nebula is that the central star or stars somehow expelled cones of gas during a late developmental stage. For MWC 922, these cones happen to incorporate nearly right angles and be visible from the sides. Supporting evidence for the cone hypothesis includes radial spokes in the image that might run along the cone walls. Researchers speculate that the cones viewed from another angle would appear similar to the gigantic rings of supernova 1987A, possibly indicating that a star in MWC 922 might one day itself explode in a similar supernova.

Hidden Galaxy IC 342
Image Credit & Copyright: Fabiomassimo Castelluzzo
Explanation: Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only glimpsed through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy. Even though IC 342's light is dimmed by intervening cosmic clouds, this deep telescopic image traces the galaxy's obscuring dust, blue star clusters, and glowing pink star forming regions along spiral arms that wind far from the galaxy's core. IC 342 may have undergone a recent burst of star formation activity and is close enough to have gravitationally influenced the evolution of the local group of galaxies and the Milky Way.
