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. A lot of groups
from all around the world joined this event to share the
beauties of the sky with others from 2-5 April. Each day is
planed for a certain activity. On April 2, science centers
worldwide will talk about the public subjects of astronomy
through web. They also hold live observations by telescopes
operated over the Internet. On April 3, one could imagine
himself as a professional astronomer and see their telescope
domes and surroundings in the observatories! Astronomers at
professional research observatories around the world will take
viewers inside their telescope domes and control rooms during a
live 24-hour webcast on 3 April. April 4
