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: Maiestria lui Dumnezeu in ordinea universului. Planeta Venus trece in fata soarelui doar de doua ori la fiecare suta de ani. Cu ochiul liber (protejat de echipament special) planeta se vede doar ca un disc negru cand trece prin fata soarelui. Au fost inregistrate doar 6 de „transits” (treceri prin fata soarelui) de cand s-a inventat telescopul in anii urmatori – 1631 si 1639, 1761 si 1769, 1874 si 1882, 2004 si 2012 (Iunie 5) (Notite din al doilea video) Primul video este filmat folosind „lungimi de unde ultraviolete extreme şi o parte a spectrului vizibil”.
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.
