Tyché : la neuvième planète du système solaire ? - wikistrike.over-blog.com

http://www.wikistrike.com/article-tiche-la-neuvieme-planete-du-systeme-solaire-67288501.html John Matese et Daniel Whitmire, deux astrophysiciens de l' Université de Louisiane à Lafayette (Etats-Unis), ont fait part de leurs travaux à propos de la possible découverte d'une nouvelle planète au sein du Système Solaire. Surnommée provisoirement Tyché (nom de la déesse grecque symbolisant la fortune, soeur de Némésis), elle aurait une masse quatre fois supérieure à celle de Jupiter et se situerait à 15.000 UA (1 Unité Astronomique = distance Terre-Soleil) - 2.250 milliards km (dans le Nuage de Oort) - soit à une distance 375 fois plus grande que celle de Pluton (raison de sa découverte tardive). Elle aurait une température de surface de -73 °C.

Un article de Wikipédia, l'encyclopédie libre. Une étoile à neutrons est un astre principalement composé de neutrons maintenus ensemble par les forces de gravitation . De tels objets sont le résidu compact issu de l' effondrement gravitationnel du cœur d'une étoile massive quand celle-ci a épuisé son combustible nucléaire, d'où leur nom. http://fr.wikipedia.org/wiki/%C3%89toile_%C3%A0_neutrons

Solar flare 'could paralyse Earth in 2013'

By Daily Mail Reporter UPDATED: 19:38 GMT, 21 September 2010 A massive solar flare could cause global chaos in 2013, causing blackouts and wrecking satellite communications, a conference heard yesterday. Nasa has warned that a peak in the sun's magnetic energy cycle and the number of sun spots or flares around 2013 could generate huge radiation levels.

The Death of Stars

Dr Fox is delivering the keynote address to an international conference on the vulnerability of electricity grids around the world to natural disaster and hostile attack. Earlier this year, the US space agency Nasa warned that a peak in the sun's magnetic energy cycle and the number of sun spots or flares around 2013 could generate huge radiation levels.

Solar storm could cause planetary disaster at any time, warn scientists

By Claire Bates UPDATED: 13:11 GMT, 26 March 2009 The Government was urged today to make contingency plans for a freak solar flare that could 'knock out' the National Grid and create severe water and food shortages. Labour former minister Graham Stringer said Britain should be prepared for a repeat of the solar storm of 1859, which hit Earth and paralysed much of the telegraph system.
On Sept. 2, 1859, an incredible storm of charged particles sent by the sun slammed into Earth's atmosphere, overpowered it, and caused havoc on the ground.
