Alan Friedman is a fascinating guy. By day he’s a maker of greeting cards and a lover of hats, but in his spare time he’s a self-proclaimed space cowboy who points a telescope skyward from his backyard in downtown Buffalo, directly into the light of the sun. Using special filters attached to his camera Friedman captures some of the most lovely details of the Sun’s roiling surface.

Une nouvelle composition réalisée par la NASA expose les différents aspects du soleil mis en évidence à différentes longueurs d’onde par le Solar Dynamics Observatory (SDO). Pour comprendre comment se compose et évolue le soleil, il faut aller l’étudier au delà de la perception. A travers la lentille d’un simple appareil photo, ou à l’œil nu, le Soleil apparaît jaune pâle, toutefois l’astre émet de la lumière dans toutes les couleurs. Aussi, les astronomes équipent leurs télescopes terrestres et spatiaux d’instruments capables d’observer la lumière émise par l’étoile dans 10 longueurs d’ondes différentes. Une nouvelle composition, publiée par la NASA présente le Soleil sous la forme d’une véritable mosaïque d’images prises dans des gammes hors du spectre visible. Avez-vous déjà partagé cet article?

The Charlie Bates Solar Astronomy Project (www.charliebates.org a 501c3 nonprofit) is the highest volume solar astronomy outreach program in the world. CBSAP brings observatory quality, narrowband solar telescopes and imaging equipment to over 150 schools and events per year. In 2012 we personally reached over 150,000 students and adults in 5 countries.

Solar Flares: What Does It Take to Be X-Class?
Sun Unleashes X6.9 Class Flare On August 9, 2011 at 3:48 a.m. EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite. These gigantic bursts of radiation cannot pass through Earth's atmosphere to harm humans on the ground, however they can disrupt the atmosphere and disrupt GPS and communications signals. In this case, it appears the flare is strong enough to potentially cause some radio communication blackouts. Sun Unleashes X6.9 Class Flare Sun Unleashes X6.9 Class Flare

Le Soleil - SpaceWeather live Real-time plots auroral activity Welcome on SpaceWeatherLive! Below you will find the status of the solar wind and the Interplanetary Magnetic Field (IMF) from the past two hours as measured by the ACE spacecraft. These parameters are the first parameters used to predict auroral activity. The redder the plots get, the better it is for auroral activity! The numbers after the word ''ETA'' on each plot shows how long it will take for the solar wind to propagate from ACE to Earth. Le Soleil - SpaceWeather live

NASA SPACECRAFT HITS THE MOON: There's a new crater on the Moon. NASA's LADEE spacecraft, on a mission since Sept. 2013 to study the lunar atmosphere, has crashed. This event was deliberate. LADEE was near the end of its planned mission and the grazing impact gave researchers a chance to study "lunar air" very close to the Moon's surface: full story. M7-CLASS SOLAR FLARE (UPDATED): Sunspot AR2036 erupted today, April 18th, at 1307 UT, producing a strong M7-class solar flare.
Latest Solar News and Updates Solar Update 4/4/2012 by Kevin VE3EN at 14:10 UTC Updated 4/4/2012 @ 14:10 UTC Solar activity remains very low with only B-Class X-Ray activity detected mostly around Sunspot 1450 and region 1451.

SunCalc - sun position, sunlight phases, sunrise, sunset, dusk and dawn times calculator SunCalc is a little app that shows sun movement and sunlight phases during the given day at the given location. You can see sun positions at sunrise, specified time and sunset. The thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon. The colors on the time slider above show sunlight coverage during the day.

Astronomy Picture of the Day

Aujourd’hui le soleil s’est arrêté. C’est, littéralement, la définition du solstice. À 6h30 précises en effet, heure de Paris (5h30 T.U.), le Soleil s’est arrêté de marcher vers le sud, et se lèvera à présent chaque jour un peu plus au nord de la position qu’il occupait la veille.

Amazingly Detailed Photo of the Surface of the Sun
En se basant sur des données recueillies par l’ESO (European Southern Observatory), les scientifiques ont réussi à donner une idée (et même une image) de ce à quoi ressemble une belle matinée ensoleillée sur Pluton. Pluton est situé 40 fois plus loin du Soleil que la Terre. Du coup, depuis cette planète naine qui ne représente qu’un cinquième de la Terre, la lumière solaire paraît 1.000 fois plus faible. De plus, cette planète naine est couverte de plaques de méthane gelé et d’une atmosphère brumeuse dans laquelle flotte le méthane gazeux. Soit des conditions qui diffèrent largement de celles que l'on peut connaitre sur Terre. A quoi ressemble le Soleil vu depuis Pluton
