Nasa Kepler Jan 2012 La previsione di Giovanni Bignami (Cagliari Festival Scienza 2011) si sta avverando: la missione Keplero della NASA continua a fare incetta di nuovi pianeti. La notizia della scoperta di 11 nuovi sistemi, per un totale di 26 nuovi pianeti, è di poche ore fa.

NASA's Kepler Announces 11 Planetary Systems Hosting 26 Planets (NASA, 01.26.12)
NASA's Kepler mission has discovered 11 new planetary systems hosting 26 confirmed planets. These discoveries nearly double the number of verified Kepler planets and triple the number of stars known to have more than one planet that transits, or passes in front of, its host star. Such systems will help astronomers better understand how planets form.
