Keck-tvillingarna separerar<\/h2>\n

Sedan ekonomerna p\u00e5 NASA dragit i n\u00f6dbromsen, kommer Kecks b\u00e4gge tvillingteleskop (10 meters speglar) p\u00e5 Mauna Kera, Hawaii, att upph\u00f6ra att arbeta tillsammans i symbios. Interferometertekniken l\u00e4ggs i malp\u00e5se, vilket bl a drabbar utforskningen av stj\u00e4rn- och planetbildning.<\/p>\n

Nya planetramsor<\/h2>\n

W-bloggsl\u00e4saren Carl-Olof B\u00f6rjson<\/strong> har uppt\u00e4ckt ett par sprillans nya planetramsor. H\u00e4r \u00e4r en trio:<\/p>\n

Tellurium inte bara p\u00e5 jorden<\/h2>\n

Grund\u00e4mnet tellurium har uppt\u00e4ckts i n\u00e5gra ljusa men groteskt gamla stj\u00e4rnor i Vintergatans halo. Stj\u00e4rnornas \u00e5lder bed\u00f6ms till runt 12 miljarder \u00e5r.<\/p>\n

Och i g\u00e5r kv\u00e4ll h\u00f6rde jag Bengt Gustavsson<\/strong>, astronomen, i radions lyssv\u00e4rda program Filosofiska rummet<\/em> p\u00e5peka att i v\u00e5ra kroppar finns atomer fr\u00e5n \u00e5tminstone 30 000 stj\u00e4rnors inre.<\/p>\n
