Via: Planetary Systems Now Forming in Orion

Explanation: How do planets form? To help find out, the Hubble Space Telescope was tasked to take a detailed look at one of the more interesting of all astronomical nebulae, the Great Nebula in Orion. The Orion nebula, visible with the unaided eye near the belt in the constellation of Orion, is an immense nearby starbirth region and probably the most famous of all astronomical nebulas. Insets to the above mosaic show numerous proplyds, many of which are stellar nurseries likely harboring planetary systems in formation. Some proplyds glow as close disks surrounding bright stars light up, while other proplyds contain disks further from their host star, contain cooler dust, and hence appear as dark silhouettes against brighter gas. Studying this dust, in particular, is giving insight for how planets are forming. Many proplyd images also show arcs that are shock waves – fronts where fast moving material encounters slow moving gas. The Orion Nebula lies about 1,500 light years distant and is located in the same spiral arm of our Galaxy as our Sun.

  1. Hey, bravo pour la creation de ce blog! Le moteur WordPress semble etre pas mal bien pour creer un tel site. J’aime bien le design que tu as choisi, c’est sleek.

  2. Merci pour les commenaitaires. Comme vous l’avez remarque, je ne suis pas tres rapide a accepter les commentaires lors de la moderation. Il faudra que je m’habitue.

    Pour ce qui est du style sleek, je suis parti de quelquechose de tres minimal. Si ca te plait ffn, c’est probablement parce que les matheux aiment presque toujours les choses les plus epurees cote web 😉

    Ceci etant dit, je pense qu’un separateur de post sera peut-etre necessaire pour faciliter la lecture. Ca pourrait aussi etre un encadre autour des posts. Je verrai ce qui est le plus facile et le mieux a faire.
