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.

In awe of God’s creation – Blue-Flame Plasma on the Face of the Sun

From NASA’s Scientific Visualization Studio. This video takes images from the Solar Dynamics Observatory and applies additional processing to enhance the structures that are visible. The result is a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet. This wavelength shows plasma in the solar atmosphere, called the corona, that is around 600,000 Kelvin. The loops represent plasma held in place by magnetic fields. They are concentrated in „active regions” where the magnetic fields are the strongest. These active regions usually appear in visible light as sunspots. The events in this video represent 24 hours of activity on September 25, 2011.
