Indonesian Astronomers Set Sights on New Observatories Astronomers are studying the feasibility of constructing two observatories in the central and eastern parts of Indonesia, where the sky is still relatively free from light pollution. Hakim Luthfi Malasan, an astronomer from the Bosscha Observatory near Bandung, told the Jakarta Globe on Friday that the two planned observatories could provide a number of direct benefits to society, such as the ability to sight the thin crescent of the new moon that determines the start of Ramadan.
