On October 22, 23 and 24, astronomers from around the world will take to the streets to show citizens what Galileo Galilei observed through his telescope 400 years ago.
The international Galilean Nights program offers the opportunity to observe the same celestial bodies that the Italian astronomer saw in 1609 , and described in 1610 in his work E l Messenger of the Stars ( Sidereus Nuncius ).
In particular, the program will focus on observing the Moon and the planet Jupiter and its four main satellites. Other objects described by Galileo in 1610, such as the Pleiades and the Orion Nebula (M42), can also be visualized. If you are looking for an activity in your city, find it on the official website http://www.galileannights.org/find_event.html.
And if in addition to observing the night sky you dare with astrophotography , the international organizers of the event have called a contest through the Flickr photography site. The call is open until October 27.
