Here is my poster design promoting the 100 Hours of Astronomy worldwide event happening in April, put on my the International Year of Astronomy 2009. Here is a bit of information outlining the event and its' purpose:
The 100 Hours of Astronomy Cornerstone Project is a worldwide event consisting of a wide range of public outreach activities, live science center, research observatory webcasts and sidewalk astronomy events.One of the key goals of 100 Hours of Astronomy is to have as many people as possible look through a telescope as Galileo did for the first time 400 years ago. 100 Hours of Astronomy will take place from 2-5 April when the Moon goes from first quarter to gibbous, good phases for early evening observing. Saturn will be the other highlight of early evening observing events.
Space is the place, so be sure to get out your telescopes :) for more information on events happening in your area, check out the 100 Hours of Astronomy website.
