For some, the action was outside the main hall. Exhibitions from various observatories, space agencies, and commercial entities attracted visitors throughout the event. The Global e-VLBI — an array of radio dishes combined electronically to create an Earth-size interferometer — went beyond the static display with four large monitors showing data coming in and being processed into images throughout the event.Exhibitions of art and astronomical images included popular displays of pictures from IYA2009 Cornerstone Project From Earth to the Universe and IYA2009 Special Project The World at Night. The latter shared space with a wall-size permanent installation of art by French master Joan Miro, appropriately enough titled The Wall of the Moon (Miro’s The Wall of the Sun resides elsewhere at UNESCO).
But as always at international gatherings, a main preoccupation of many attendees was meeting new friends and colleagues. The students, many from developing countries where such opportunities are rare, especially relished the chance. The halls looked every bit like a UN venue with the mix of cultures. The receptions held on both nights presented even greater opportunities for mingling. An IAU symposium titled “The Role of Astronomy in Society and Culture” continues during this week, also at UNESCO.The opening event of IYA2009 was more than speeches. The diversity of the participants in age, background, and country of origin made that clear enough. And it was particularly important for those from developing countries. As Cesarsky put it, “They are seeing the same sky as we are and they deserve to see the same discoveries we are and to make some discoveries for themselves in the future.”
That perspective also fits the unprecedented public astronomy outreach now underway with the theme: The Universe, Yours to Discover.
