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).

Specifically, a large portion of Enceladus pictured above is illuminated primarily by sunlight first reflected from the planet Saturn. 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.

{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.

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.
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.
2012 September 17 - A Solar Filament Erupts 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 September 17 Explanation: What's happened to our Sun? Mars Discovery: NASA touts Curiosity data that points to historic discovery. Andrew Bodrov/360Cities.net/NASA/JPL/Caltech. Curiosity is living up to its name. The NASA rover currently wheeling itself around Mars has apparently sent back some very interesting data from the Red Planet in the form of a soil sample that shows ... well, something. From the sounds of it, something big. But for now at least, that's all anyone is willing to say. Scientists at NASA's Jet Propulsion Laboratory in Pasadena are keeping their lips sealed for the time being while they run additional tests to make sure the discovery holds up. "This data is gonna be one for the history books," John Grotzinger, the rover mission's principal investigator, told NPR last week for a the buzz-inciting segment that aired today. Of course, the reason that NASA is keeping the potential find (mostly) under wraps is because it may turn out to be nothing but a false alarm, something that's happened before to the mission. So why doesn't Grotzinger want to share his exciting news?
