Active Region 1429 may not only look, to some, like an angry bird -- it has thrown off some of the most powerful flares and coronal mass ejections of the current solar cycle.

Its mystery has always captivated us and the inevitable discoveries to come will add to the many cosmological insights we already have. But let this list serve as a warning for any weary inter-solar travelers. Our planet maintains a high ratio of oxygen to carbon. On Neptune, one can find constant jet stream winds that whip around the planet at terrifying speeds. Nick-named Bellerophon, in honor of the Greek hero who tamed the winged horse Pegasus, this gas giant is over 150 times as massive as earth and made mostly of hydrogen and helium. The densest and most massive exoplanet to date is a world known as COROT-exo-3b. On Mars a dust storm can develop in a matter of hours and envelope the entire planet within a few days. Simply put, this planet is the hottest planet ever discovered. Jupiter’s atmosphere brews storms twice as wide as the Earth itself. (Note: Pluto is technically no longer classified as a planet).

SpaceShipTwo goes supersonic on first powered flight - space - 29 April 2013 Video: First rocket-powered flight of SpaceShipTwo Private joyrides and research trips to the edge of space just got closer to reality. Today Virgin Galactic's suborbital plane SpaceShipTwo completed its first rocket-powered test flight high over the Mojave desert. The commercial space plane, docked to its carrier mothership WhiteKnightTwo, took off from the Mojave Air and Space Port in southern California at 14.02 UTC Monday. The pair rose to an altitude of about 14 kilometres, and then the carrier ship released SpaceShipTwo. Moments later, test pilots Mark Stucky and Mike Alsbury triggered ignition of the rocket motor, which flared dramatically, prompting cheers and applause from spectators on the ground. The engine burn lasted for 16 seconds. Transformational flight Ultimately, the ship's rockets will fire for 70 seconds, allowing it to carry six passengers and two pilots to a maximum altitude of about 100 kilometres, the unofficial boundary between Earth's atmosphere and space.

Specifically, a large portion of Enceladus pictured above is illuminated primarily by sunlight first reflected from the planet Saturn. {sciences²} Soleil eruptionAurores boréales garanties, satellites menacés, pas de permission de sortie pour les astronautes de l'ISS, risques de dysfontionnements pour le GPS... C'est la météo spatiale du jour. Hier, le Soleil nous a envoyé sa plus grosse éruption depuis cinq ans, lorsqu'il a entamé son creux d'activité le plus prononcé depuis un siècle. Mais là, il se réveille sérieusement. Soleil le 8 mars C'est la tache solaire n°1429 qui s'éclate ainsi. Le Soleil est encore à mi chemin, au mieux, de sa montée en puissance de son nouveau cycle d'activité. De nombreux satellites observent l'astre et leur durée de vie réelle, très au delà des spécifications initiales Ejection coronale Soho(Soho devait durer 10 ans) a permis de constituer des bases de données de plus en plus pertinentes. A droite, l'éjection du 7 mars qui doit atteindre notre planète aujourd'hui, vue par le satellite Soho. Pour suivre l'activité du Soleil, il est possible de se rendre ici.

100,000 Stars 9 November Live feeds for Olympic torch in Space Olympics Robert Z. Pearlman, CollectSpace.com Space.com 1 hour ago AP / OlympicTorch2014.com Former Soviet cosmonaut Valentina Tereshkova, 76, speaks during torch relay celebrations in the Yaroslavl region, about 350 kilometers (217 miles) northeast of Moscow. Cosmonaut Valentina Tereshkova, the first woman to launch into space on a rocket's flame, took hold of the Olympic flame on Saturday, completing a leg of the 2014 Winter Games' torch relay. At the same time, an unlit torch to be used in the Olympic Games' opening ceremonies was being readied for its own trip, first to its launch site and then into space. In June 1963, Tereshkova lifted off on the Soviet Vostok 6 mission to become the first woman to fly into space. "Today we have a very important day," Tereshkova said, according to a summary published by the Olympic Winter Games organizing committee. "In space, we have to hide emotions far, far away because of the responsibility," Tereshkova remarked.

Earth’s magnetic field provides vital protection Earth’s magnetic field provides vital protection Propagation of a solar wind stream 8 March 2012 A chance alignment of planets during a passing gust of the solar wind has allowed scientists to compare the protective effects of Earth’s magnetic field with that of Mars’ naked atmosphere. The result is clear: Earth’s magnetic field is vital for keeping our atmosphere in place. The alignment took place on 6 January 2008. They found that while the pressure of the solar wind increased at each planet by similar amounts, the increase in the rate of loss of martian oxygen was ten times that of Earth’s increase. Such a difference would have a dramatic impact over billions of years, leading to large losses of the martian atmosphere, perhaps explaining or at least contributing to its current tenuous state. Artist's impression of Mars’ magnetosphere The result proves the efficacy of Earth’s magnetic field in deflecting the solar wind and protecting our atmosphere.

Big News From Mars? Rover Scientists Mum For Now hide captionNASA's Mars rover Curiosity dug up five scoops of sand from a patch nicknamed "Rocknest." A suite of instruments called SAM analyzed Martian soil samples, but the findings have not yet been released. NASA/JPL-Caltech Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem. They have some exciting new results from one of the rover's instruments. It's a bind scientists frequently find themselves in, because by their nature, scientists like to share their results. The exciting results are coming from an instrument in the rover called SAM. SAM is a kind of miniature chemistry lab. Grotzinger says they recently put a soil sample in SAM, and the analysis shows something remarkable. Grotzinger can see the pained look on my face as I wait, hoping he'll tell me what the heck he's found, but he's not providing any more information. So why doesn't Grotzinger want to share his exciting news? He did break down and tell his family.

2012 January 24 - January Aurora Over Norway Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2012 January 24 Explanation: What's that in the sky? An aurora. Ecoutez le bruit d’une éruption solaire. (Vidéo) Une nouvelle vidéo nous permet d’entendre les sons frénétiques d’une tempête solaire, basée sur les données enregistrées par deux engins spatiaux alors qu’ils étaient bombardés par des particules chargées au cours d’une récente éruption solaire. La vidéo est un aperçu visuel et auditif du soleil au début du mois de mars, quand il a fait éclater la plus forte tempête solaire depuis 6 ans. La tempête a déclenché une vague de plasma solaire et de particules énergétiques, que la sonde Messenger de la NASA autour de mercure et l’observatoire solaire et héliosphèrique (SoHO), un satellite autour du soleil, ont enregistré. Robert Alexander, à l’Université du Michigan à Ann Arbor, a créé la vidéo en utilisant une technique qui "sonifie" les mesures à partir de deux engins spatiaux. Alexander travaille en collaboration avec la NASA pour représenter les informations en son, pouvant ainsi aider les scientifiques à l’exploitation et à l’analyse de données.

Scientist Claims Our Solar System Evicted A Planet So Earth Could Survive Colorado scientist David Nesvorny was running solar system evolutionary simulations recently when he realized that during 6,000 different simulations the Earth couldn’t survive during the system’s early years based on the current planetary count. Once Nesvorny added another planet to the system however Earth survived as expected. According to his work our solar system at one point had a ninth planet, a gas giant that was nudged out of the system billions of years ago to make room for Earth’s survival. According to the Mother Nature Network “gas giant number five” started off bound together with Saturn and Jupiter and pushed out lighter planets including Neptune and Uranus eventually to be pushed out of the system on its own after a collision with Jupiter. According to his work David said the planet was likely orbiting about 15 times further from the sun than our own planet.
