Nous vivons une période cruciale. Les scientifiques nous disent que nous avons 10 ans pour changer nos modes de vie, éviter d'épuiser les ressources naturelles et empêcher une évolution catastrophique du climat de la Terre.

Il faut que chacun participe à l'effort collectif et c'est pour sensibiliser le plus grand monde que j'ai conçu le film HOME.

Afin de diffuser ce film le plus largement possible, il fallait qu'il soit gratuit. Un mécène, le groupe PPR, a permis qui le soit. EuropaCorp, qui en assure la distribution, s'est engagé à ne faire aucun bénéfice car HOME n'a aucune ambition commerciale.

J'aimerais que ce film devienne aussi votre film. Partagez-le. Et agissez.

Rare Radio Supernova in Nearby Galaxy is Nearest Supernova in Five Years

A Hubble Space Telescope image (left) of the galaxy M82 shows hydrogen gas (red) breaking out from the central starburst (box), a region of intense star formation. A May 2008 VLA image of the starburst region (top left) clearly shows the supernova (SN 2008iz), which probably exploded in January 2008. The two high-resolution VLBA images (lower right) show an expanding shell at the scale of a few light days and proves that the transient source was the result of a supernova.
