La région active AR 1719 à la surface du Soleil (photo SDO) Il y a tout juste une semaine, le 11 avril 2013 à précisément 7h16 TU (9h16 en France métropolitaine), un flux de particules électriquement chargées s’échappait de la surface du Soleil, depuis la région active AR 1719 située face à la Terre. Une éjection de masse coronale ( Coronal Mass Ejection, CME ) d’une ampleur modérée issue d’une éruption solaire classée M6.
Magie des aurores polaires. Cette superbe timelapse video nommée “Spirits”, réalisée par Nicholas Buer nous emmène dans le nord de la Norvége, à la découverte des fréquentes et féériques aurores (surtout en ce moment, à l’approche du maximum de l’activité solaire prédit pour mi-2013) qui illuminent les eaux calmes des lacs. Le ciel est envahi par ces brumes verdoyantes et ondulantes qui survolent les brouillards. http://www.lecosmographe.com/blog/video-magie-des-aurores-boreales-ciel-de-norvege/#.UVzVadGI70M

Jaw-Dropping Slow Motion Footage of Lightning Shot at 7,207 FPS

http://www.petapixel.com/2012/07/24/jaw-dropping-slow-motion-footage-of-lightning-shot-at-7207-fps/ Photographer Tom Warner shot this slow motion incredible video of lightning at 7,207 frames per second. APOD writes , The above lightning bolt starts with many simultaneously creating ionized channels branching out from an negatively charged pool of electrons and ions that has somehow been created by drafts and collisions in a rain cloud.
http://www.boston.com/bigpicture/2010/04/icelands_disruptive_volcano.html Today, British civil aviation authorities ordered the country's airspace closed as of noon, due to a cloud of ash drifting from the erupting Eyjafjallajökull volcano in Iceland. The volcano has erupted for the second time in less than a month, melting ice, shooting smoke and steam into the air and forcing hundreds of people to flee rising floodwaters. The volcanic ash has forced the cancellation of many flights and disrupted air traffic across northern Europe, stranding thousands of passengers.

An eclipse from space with a two-way Moon

http://blogs.discovermagazine.com/badastronomy/2011/03/06/an-eclipse-from-space-with-a-two-way-moon/ This is pretty wild: a partial solar eclipse on March 4, 2011 as seen from NASA’s Solar Dynamics Observatory! Watch as the Moon slips in front of the face of the Sun in this video : Cool!

The Angry Red Galaxy

http://blogs.discovermagazine.com/badastronomy/2011/01/14/the-angry-red-galaxy/ [Bonus points to any middle-aged readers who recognize the title * .] I still get a thrill every time I see a particularly beautiful image of an astronomical object. But there are some that transcend that beauty, adding a dimension of what-the-what?

Los Cielos del Ecuador, Chimborazo Volcano

http://www.astrosurf.com/sguisard/Pagim/Chimborazo.html With an altitude of 6268 meters (20564 ft) above sea level, Chimborazo volcano is the highest summit in Ecuador but of course not the highest summit on the planet. This record belongs to Mount Everest (8848 metres / 29029 ft above sea level). However, because the Earth is not a perfect sphere but rather an oblate spheroid (a sphere flattened along the axis from pole to pole such that there is a bulge around the equator) and that Chimborazo is very close to the equator line (only -1 degree in latitude), Chimborazo is known as the "the farthest location from the center of the Earth". 6384.687 Km against 6382.467 Km for Everest that is, a difference of 2.220 Km/1.38 miles. Ecuatorian people will kindly and proudly remind you about this fact "Chimborazo, el punto mas lejano del centro de la Tierra".
