The poll I just closed asked if you knew when was the International Year of Astronomy (IYA). Only two people knew. One of two things is true. Nobody comes to my page, or few people know this is the International Year of Astronomy .
In any case, in 1609 Galileo Galilei from Italy, used a telescope to start the scientific study of the sky. To celebrate this four hundred year anniversary, UNESCO declared 2009 the IYA.
There are a few more links to this effect in this page. I have posted a few notes and written some. All this year I will be reminding you about this historic event.
