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.

NASA: Coming 2013 – Solar Maximum – Semne in cer pentru anul 2013

Photo source – sursa pozei NASA picture of the day

Expertii spun ca in 2013 se va petrece evenimentul ‘Solar Max’ care se intampla tot la 11 ani. In anul 2013 se prevad multe furtuni geomagnetice si va fi o activitate sporita de ‘aurore’ cum nu a mai fost de multa vreme. Deja s-a evidentiat activitatea in weekendul de 14 Iulie cand pentru 14 ore s-a vazut aurora in mai multe locuri pentru un timp de 36 de ore…vezi video (5 min)

Experts say ‘Solar Max’ is due in the year 2013. When it arrives the peak of its 11 year sun spot cycle will bring more solar flares, more coronal mass ejections, more geomagnetic storms and more auroras than we have experienced in quite some time.  On the weekend of July 14, 2012 skywatchers around the world got a taste of things to come. It was mid Saturday in North America when a coronal mass ejection or CME crashed into earth’s magnetic field and triggered the most sustained display of auroras in years. For more than 36 hours, magnetic storms circled earth’s poles, northern lights spilled across the Canadian border to the United States as far south as California, Colorado, Kansas and Arkansas. In the SOuthern hemisphere skies turned red in Tasmania and New Zealand, while the aurora australis pirouetted around the South Pole. The source of the CME was giant sun spot…. see video for rest (5 min)

In awe of God’s creation – Photo of Aurora Borealis or Northern Lights (What are these mysterious lights?)

Northern lights over Ireland – Aurora peste Irlanda

The northern lights, one of several astronomical phenomena called polar lights (aurora polaris), are shafts or curtains of colored light visible on occasion in the night sky.

Polar lights (aurora polaris) are a natural phenomenon found in both the northern and southern hemispheres that can be truly awe inspiring. Northern lights are also called by their scientific name,aurora borealis, and southern lights are called aurora australis.

Sten Odenwald, author of The 23rd cycle, learning to live with a stormy star (New York, Columbia University Press, c2001), provides insight to how northern lights are formed:

The origin of the aurora begins on the surface of the sun when solar activity ejects a cloud of gas. Scientists call this a coronal mass ejection (CME). If one of these reaches earth, taking about 2 to 3 days, it collides with the Earth’s magnetic field. This field is invisible, and if you could see its shape, it would make Earth look like a comet with a long magnetic ‘tail’ stretching a million miles behind Earth in the opposite direction of the sun.

When a coronal mass ejection collides with the magnetic field, it causes complex changes to happen to the magnetic tail region. These changes generate currents of charged particles, which then flow along lines of magnetic force into the Polar Regions. These particles are boosted in energy in Earth’s upper atmosphere, and when they collide with oxygen and nitrogen atoms, they produce dazzling auroral light.

Odenwald further tells us „Aurora are beautiful, but the invisible flows of particles and magnetism that go on at the same time can damage our electrical power grid and satellites operating in space. This is why scientists are so keen to understand the physics of aurora and solar storms, so we can predict when our technologies may be affected.”

Can I see them anywhere?
Yes. Although more frequent at higher latitudes, closer to the poles (such as in Canada, Alaska, Antarctica), they have been seen closer to the equator as far south as Mexico. To view them, look in the direction of the closest pole (the northern horizon in the northern hemisphere, the southern horizon in the southern hemisphere).

Can I see them at any time of the year?
Yes. In some areas, such as Alaska or Greenland, they may be visible most nights of the year. And they occur at any time of the day, but we can’t see them with the naked eye unless it’s dark.

What causes the colors and patterns?
Colors and patterns are from the types of ions or atoms being energized as they collide with the atmosphere and are affected by lines of magnetic force. Displays may take many forms, including rippling curtains, pulsating globs, traveling pulses, or steady glows. Altitude affects the colors. Blue violet/reds occur below 60 miles (100 km), with bright green strongest between 60-150 miles (100-240 km). Above 150 miles (240 km) ruby reds appear.

Fun Facts about northern lights:

  • According to Neil Bone (The aurora: sun-earth interactions, 1996), the term aurora borealis–northern dawn–is jointly credited to have first been used by Pierre Gassendi (1592-1655) and Galileo Galilei (1564-1642), who both witnessed a light display on Sept. 12, 1621. However, Bone also includes a description of the northern lights made 1,000 years prior by Gregory of Tours (538-594.) It included the phrase, „… so bright that you might have thought that day was about to dawn.”
  • Auroras have been observed since ancient times.
  • The height of the displays can occur up to 1000 km (620 miles), although most are between 80-120 km.
  • Auroras tend to be more frequent and spectacular during high solar sunspot activity, which cycles over approximately eleven years.
  • Some displays are particularly spectacular and widespread and have been highlighted in news accounts. Examples include auroral storms of August-September, 1859, Feb 11, 1958, (lights 1250 miles wide circled the Arctic from Oregon to New Hampshire) and March 13, 1989, (the whole sky turned a vivid red and the aurora was seen in Europe and North America as far south as Cuba).
  • Legends abound in northern cultures to explain the northern lights. Some North American Inuit call the aurora aqsarniit(“football players”) and say the spirits of the dead are playing football with the head of a walrus. Often legends warn children that the lights might come down and snatch them away.
  • June 1896, Norwegian Kristian Birkeland, the “father of modern auroral science,” suggested the theory that electrons from sunspots triggered auroras.
  • Yellowknife (Northwest Territories, Canada) is the capital for aurora tourism.
  • The earliest known account of northern lights appears to be from a Babylonian clay tablet from observations made by the official astronomers of King Nebuchadnezzar II, 568/567 BC.
  • Some people claim to hear noises associated with the northern lights, but documenting this phenomenon has been difficult.
