Meteor sky show set to reach peak 17 November 2011Last updated at 13:22 The Leonids peak on Thursday night The annual Leonids meteor shower is set to reach its peak on Thursday, astronomers say. The shower is caused by the Earth moving through a shower of debris from the comet Tempel-Tuttle. In most years, the shower produces some 10-15 meteors per hour. As is usual, city lights or moonlight could obscure the view for observers. Although normally a quiet meteor shower, every 33-34 years the Leonids put on a major display, known as a meteor storm. The last time this happened was 1999, when more than 1,000 meteors per hour were could be seen. However, many stargazers will still be out this evening to watch, in case they have a stroke of luck. The "radiant" - the apparent origin in the sky - of the meteors lies in the constellation Leo, and it is from here that the Leonids take their name.

Boletim em Órbita nº 91 (Edição Especial) A conquista da Lua foi uma das maiores aventuras da Humanidade que continua a marcar gerações. A aventura dos doze astronautas que pisaram o solo lunar marcou o culminar de um esforço e de uma corrida entre duas super-potências que ‘lutavam’ no espaço pela hegemonia numa guerra que se dizia fria. Porém, mesmo 40 anos após as primeiras explorações lunares, ainda existem pessoas que duvidam de que alguma vez o Homem tenha caminhado sobre o nosso satélite natural.

Stellarium LHC_Homepage Galaxy Video: Meteors, Aurora Borealis And Milky Way Shimmer In Time-Lapse Extravaganza Unless there's a meteor shower, we don't usually notice things moving up in space. Sped up and enhanced, however, the night sky becomes a bustling world—the clouds, the Milky Way and everything in between can be seen shifting and changing in ways the naked eye could never notice. "Temporal Distortion," above, gives just such a view. (Story continues below video.) Temporal Distortion from Randy Halverson on Vimeo. The video was created by photographer Randy Halverson. The camera moves slowly along a dolly (some behind the scenes shots can be found here), and it feels like the speed at which we were meant to see the night sky. Other highlights include a meteor's spectacular trail at the 53-second mark and a couple of ghostly deer at 1:27. Halverson notes, "Most of the video was shot near the White River in central South Dakota during September and October 2011, there are other shots from Arches National Park in Utah, and Canyon of the Ancients area of Colorado during June 2011.

NASA Earth Observatory 10 applications indispensables en astronomie pour iPad et iPhone Sélection des meilleures applications pour vous repérer dans le ciel étoilé et vous initier à l’astronomie. Depuis la naissance de l’iPhone puis un peu plus tard celle de l’iPad, les applications pour iOS sur le thème de la découverte et l’initiation en astronomie se sont multipliées. Certaines ont connu de très beaux succès et maintiennent leurs leadership dans cette niche. Pour beaucoup, il a fallu évoluer avec le temps, gommer les défauts de jeunesse, les excès et fioritures, repenser la navigation, la prise en main et tendre vers l’épure. Les « Atlas du ciel virtuels » Quelques applications qui vont vous faire découvrir le ciel autrement, en vous amusant. Skypix Le principal attrait de cette application développée par le magazine Science & Vie est la large contribution du brillant journaliste scientifique et astro-photographe Serge Brunier.
