The International Year of Astronomy 2009 has officially begun! It literally started with a bang for residents of the Brazilian city Rio de Janeiro, as a grand fireworks display was held in honour of the year, with explosions in the shapes of stars, comets, and even planets! But astronomy-themed events haven't been limited to any one location. IYA2009 is a global endeavour, and activities already occurring reflect that.
