From NASA – Watch Earth’s magnetic shield protect the planet from a pelting by the solar wind. See how the sun’s energy drives a remarkable planetary engine, the climate.

This video, originally created by NASA’s Scientific Visualization Studio as part of a full-length planetarium film called „Dynamic Earth,” was awarded first place in the video category in the 2013 International Science and Engineering Visualization Challenge, sponsored by the journal Science and the National Science Foundation.
While the full movie highlights many aspects of the Earth’s complexity, the contribution from the SVS depicts the vast scale of the sun’s influence on the Earth, from the flowing particles of the solar wind and the fury of coronal mass ejections to the winds and currents driven by the solar heating of the atmosphere and ocean.

The data visualization in this excerpt represents a high point in the Scientific Visualization Studio’s work in recent years to show „flows” – ocean currents, winds, the movement of glaciers. Using data from sophisticated NASA models, the studio’s visualizers have figured out how to illustrate the velocities of these natural phenomena.

Transcript:

 Narrator: What safeguards our solar system… is our star. The sun provides a shield, stretching beyond the last planet in its orbit: a force field that deflects these „cosmic rays.” But these „solar winds” can be dangerous too, especially during outbursts called coronal mass ejections. Want a vision of earth gone wrong? Just look at what solar storms do our sister planet, Venus. They strip away lighter elements in its upper atmosphere, hydrogen, oxygen and the molecule they form: water. What’s left is a witch’s brew of noxious chemicals including thick sulfurous clouds. How has Earth avoided the grim fate of Venus? We can see the answer as the solar storm approaches Earth.

Our planet has a protective shield all it’s own– A powerful magnetic field generated deep within its core. In fact, that’s just our first line of defense. Much of the solar energy that gets through is reflected back to space by clouds, ice, and snow. The energy that Earth absorbs is just enough to power a remarkable planetary engine: the climate.

It’s set in motion by the unevenness of solar heating, due in part to the cycles of day and night, and the seasons that cause warm tropical winds to blow toward the poles and cold polar air toward the equator. Wind currents drive surface ocean currents.

This computer simulation shows the Gulf Stream winding its way along the coast of North America.  This great ocean river carries enough heat energy to power the industrial world a hundred times over. It breaks down in massive world pools that spread warm tropical waters over northern seas.

Below the surface they mix with cold deep currents that swirl around under sea ledges and mountains.

Earth’s climate engine has countless moving parts: tides and terrain, cross winds and currents– all working to equalize temperatures around the globe.

In Awe of God’s Creation – NASA ne arata cum cometa ISON se apropie de soare – ISON comet filmed by NASA – Coplesit de Creatia lui Dumnezeu

Cometa Ison apare in partea stanga, jos,
in aceasta filmare de 23 de secunde.
Daca cometa ISON nu va fi distrusa de caldura soarelui,
va fi vizibila pe pamant, cu ochiul liber (fara telescop),
pe data de 28 noiembrie 2013.

Explanation: Still intact, on November 21 Comet ISON (C/2012 S1) swept into this animated field of view (left) from the HI-1 camera on the STEREO-A spacecraft. The camera has also captured periodic Comet Encke, Mercury, and Earth, with the Sun cropped out of the frame at the right, the source of the billowing solar wind. From STEREO’s perspective in interplanetary space, planet Earth is actually the most distant of the group, seen in its orbit beyond the Sun. Mercury is closest, but both planets are still so bright they create sharp vertical lines in the camera’s detector. Both comets clearly sport substantial tails, but ISON is closer to the camera and will continue to move more rapidly through the field. Cameras on STEREO and SOHO spacecraft will be able to follow Comet ISON as it falls towards its close encounter with the Sun on November 28, even as ISON gets more difficult to see in the bright dawn skies of planet Earth.

Dailymail.co.uk via  Descopera.ro – ISON, supranumită „cometa secolului”, care poate fi văzută cu ochiul liber în această perioadă, oferă pasionaţilor de astronomie imagini spectaculoase, însă ar putea să se fragmenteze şi să explodeze în zilele viitoare, pe măsură ce se apropie tot mai mult de Soare. Sâmbătă, experţii au anunţat că ISON a intrat în „modul complet de erupţie”, după ce gradul ei de strălucire a crescut spectaculos în doar 24 de ore. Oamenii de ştiinţă sunt de părere că ISON va deveni şi mai strălucitoare în săptămânile următoare. ISON poate fi urmărită cel mai bine pe un cer întunecat, când linia orizontului nu este obturată, din zonele rurale.

NASA Comet ISON’s Path Thru the Solar System
Traiectoria lui ISON prin sistemul solar

Comet C/2012 S1 (ISON) may become one of the most dazzling in decades when it rounds the sun later this year. Like all comets, ISON is a clump of frozen gases mixed with dust. Often described as „dirty snowballs,” comets emit gas and dust whenever they venture near enough to the sun that the icy material transforms from a solid to gas, a process called sublimation. Jets powered by sublimating ice also release dust, which reflects sunlight and brightens the comet.

Based on ISON’s orbit, astronomers think the comet is making its first-ever trip through the inner solar system. Before beginning its long fall toward the sun, the comet resided in the Oort comet cloud, a vast shell of perhaps a trillion icy bodies that extends from the outer reaches of the planetary system to about a third of the distance to the star nearest the sun.

Formally designated C/2012 S1 (ISON), the comet was discovered on Sept. 21, 2012, by Russian astronomers Vitali Nevski and Artyom Novichonok using a telescope of the International Scientific Optical Network located near Kislovodsk.

The first of several intriguing observing opportunities occurs on Oct. 1, when the inbound comet passes about 6.7 million miles (10.8 million km) from Mars. During this time, the comet may be observable to NASA and ESA spacecraft now working at Mars, including the Curiosity rover.

Fifty-eight days later, on Nov. 28, ISON will make a sweltering passage around the sun. The comet will approach within about 730,000 miles (1.2 million km) of its visible surface, which classifies ISON as a sungrazing comet. In late November, its icy material will furiously sublimate and release torrents of dust as the surface erodes under the sun’s fierce heat, all as sun-monitoring satellites look on. Around this time, the comet may become bright enough to glimpse just by holding up a hand to block the sun’s glare.

Sungrazing comets often shed large fragments or even completely disrupt following close encounters with the sun, but for ISON neither fate is a forgone conclusion.

Following ISON’s solar encounter, the comet will depart the sun and move toward Earth, appearing in evening twilight through December. The comet will swing past Earth on Dec. 26, approaching within 39.9 million miles (64.2 million km) or about 167 times farther than the moon.

In Awe of God’s Creation – NASA releases filming of Sun’s Canyon of Fire (from Sept 29) – „Canionul de foc” – cele mai spectaculoase imagini capturate de NASA pe suprafata Soarelui (VIDEO)

In 29 septembrie, Solar Dynamics Observatory NASA a filmat aceste imagini din acest video. Exploziile solare sunt insotite frecvent de emisii de plasma solara, insa o furtuna magnetica incepe numai in cazul in care norul de plasma ajunge in apropiere de Pamant.

Soarele face posibilă prezenţa formelor de viaţă pe Terra, însă reprezintă un loc deloc ospitalier. Pentru a ne reaminti de condiţiile existente la suprafaţa stelei aflate în centrul sistemului nostru solar, NASA a dat publicităţii un clip video compus din date colectate de sateliţii agenţiei spaţiale americane ce înfăţişează cea mai recentă ejecţie de masă coronală a Soarelui. În cadrul acestui eveniment spectaculos din punct de vedere vizual, Soarele a lansat un filament magnetic lung de peste 320.000 de kilometri. Filamentul, ce s-a întins pe o distanţă de 25 de ori mai mare decât diametrul Pământului – a lăsat în urma sa o perspectivă spectaculoasă asupra câmpurilor magnetice ce-l ţineau în loc.

NASA a supranumit acest fenomen „canionul de foc”, iar numele ales de cercetătorii americani reprezintă o descriere potrivită a evenimentului înregistrat de sateliţii americani pe 29 şi 30 septembrie, atunci când ejecţia de masă coronală a fost lansată înspre Terra cu o viteză de aproximativ 850 de kilometri pe secundă.

A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun’s atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. Visualizers at NASA’s Goddard Space Flight Center in Greenbelt, Md. combined two days of satellite data to create a short movie of this gigantic event on the sun.

In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields.

These images were captured on Sept. 29-30, 2013, by NASA’s Solar Dynamics Observatory, or SDO, which constantly observes the sun in a variety of wavelengths.

Different wavelengths help capture different aspect of events in the corona. The red images shown in the movie help highlight plasma at temperatures of 90,000° F and are good for observing filaments as they form and erupt. The yellow images, showing temperatures at 1,000,000° F, are useful for observing material coursing along the sun’s magnetic field lines, seen in the movie as an arcade of loops across the area of the eruption. The browner images at the beginning of the movie show material at temperatures of 1,800,000° F, and it is here where the canyon of fire imagery is most obvious.

By comparing this with the other colors, one sees that the two swirling ribbons moving farther away from each other are, in fact, the footprints of the giant magnetic field loops, which are growing and expanding as the filament pulls them upward. Find out more at NASA‘s website.

In the video you will see some strings connecting over the canyon, from what I’ve read, the consensus is that „The “strings” that you see is plasma from the sun that follows the magnetic field in that particular area of the sun. The magnetic field sort of re-aligns itself after the coronal mass ejection. So your actually seeing the sun’s magnetic field, made visible by plasma that runs through it (strings).”

Breathtaking video!

ROMANIAN:

Din cauză că nu ne putem uita direct la el, pierdem mare parte din spectacolul oferit de Soare. Din fericire, specialiştii NASA studiază Soarele pentru noi, iar acum au făcut public un video care prezintă erupţia splendidă de vara trecută.

În ziua de 19 iulie 2012, pe Soare a avut loc o erupţie ce a provocat o ejecţie puternică de particule încărcate electric producând un fenomen cunoscut sub numele de ploaie coronală.

Plasma fierbinte din coroana solară s-a răcit şi s-a condensat de-a lungul câmpurilor magnetice din regiune. Câmpurile magnetice sunt invizibile dar plasma încărcată electric este forţată să se deplaseze de-a lungul liniilor.

Erupţiile solare pot fi foarte diferite. Unele vin doar cu un flux de particule încărcate electric, altele cu ejecţii majore de materiale solare iar altele cu structuri mobile complexe asociate cu schimbări ale liniilor câmpului magnetic la nivelul coroanei solare.

În timpul erupţiei din vara anului trecut, au avut loc toate cele trei tipuri de explozii. Pe parcursul zilei de 20 iulie 2012, plasma din coroană s-a răcit şi s-a condensat în jurul câmpurilor magnetice puternice.

Imaginile de mai jos au fost surprinse la fiecare 12 secunde cu ajutorul instrumentului NASA, Solar Dynamics Observatory’s Atmospheric Imaging Assembly (AIA), fiecărei secunde din acest video corespunzându-i 6 minute în timp real.

ENGLISH:

Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun’s atmosphere, the corona.

On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun’s lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays – a phenomenon known as coronal rain.

Over the course of the next day, hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, themselves, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface.

The footage in this video was collected by the Solar Dynamics Observatory’s AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

English: What’s Up for June? It won’t happen again until December 2117. On June 5th, 2012, Venus will transit(pass in front of) the face of the sun in an event of both historical and observational importance. First video shows Venus’ transit and the second video explains it.
Launched on Feb. 11, 2010, the Solar Dynamics Observatory, or SDO, is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun’s atmosphere, magnetic field and also provide a better understanding of the role the sun plays in Earth’s atmospheric chemistry and climate. SDO provides images with resolution 8 times better than high-definition television and returns more than a terabyte of data each day.On June 5 2012, SDO collected images of the rarest predictable solar event–the transit of Venus across the face of the sun. This event lasted approximately 6 hours and happens in pairs eight years apart, which are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.The videos and images displayed here are constructed from several wavelengths of extreme ultraviolet light and a portion of the visible spectrum. The red colored sun is the 304 angstrom ultraviolet, the golden colored sun is 171 angstrom, the magenta sun is 1700 angstrom, and the orange sun is filtered visible light. 304 and 171 show the atmosphere of the sun, which does not appear in the visible part of the spectrum.

In Awe of Creation – NASA | Massive Solar Flare March 6th – Eruptie Solara

Un exemplu de „semne in cer….”

This movie of the March 6, 2012 X5.4 flare was captured by the Solar Dynamics Observatory (SDO) in the 171 and 131 Angstrom wavelength. One of the most dramatic features is the way the entire surface of the sun seems to ripple with the force of the eruption. This movement comes from something called EIT waves – because they were first discovered with the Extreme ultraviolet Imaging Telescope (EIT) on the Solar Heliospheric Observatory. Since SDO captures images every 12 seconds, it has been able to map the full evolution of these waves and confirm that they can travel across the full breadth of the sun. The waves move at over a million miles per hour, zipping from one side of the sun to the other in about an hour. The movie shows two distinct waves. The first seems to spread in all directions; the second is narrower, moving toward the southeast. Such waves are associated with, and perhaps trigger, fast coronal mass ejections, so it is likely that each one is connected to one of the two CMEs that erupted on March 6.

In awe of Creation – The spectacular Sun – from NASA

I know I have a few readers who do not believe God is the Creator of this Universe, like I do. But I think we can firmly agree that we are certainly in awe of the vastness and complexity of our Universe. For some of us there is no doubt who gets the credit for it- ALMIGHTY GOD. So, even if you don’t believe God made this Universe, join me in an awe-filled  look at the sun, the moon and the Universe. (Now that we got that explained-I am going to post NASA pictures on the blog from time to time. Hope you enjoy them as much as I do)

Magnetic Loops A’Crackling on the Sun

The latest amazing close-up shot of solar activity is available courtesy of Steele Hill and NASA’s Solar Dynamics Observatory. Steele is a Goddard media specialist who sends out packages of sun images and videos that get displayed in hundreds of museums and science centers. In Steele’s own words:

“When a substantial active region rotated into view, it was a hot-bed of dynamic motion and loops (Mar. 21-22, 2011). As observed by Solar Dynamics Observatory (SDO) in extreme ultraviolet light, the region’s powerful magnetic forces tangled, broke apart and reconnected with a vengeance, even popping off a few flares. Very tight close-ups such as this one had not been possible until the SDO began operations just a year ago.”

Explanation: The sun was captured in 1973 throwing one of the largest eruptive prominences ever recorded.  The sun will never explode, and a solar flare will never destroy the earth.  The sun is made of mostly hydrogen and helium. The sun’s center is so hot that when hydrogen nuclei collide, they stick together and release energy – a process called nuclear fusion No one knows why the center of the sun emits so few neutrinos.
