Explanation:
As twilight sweeps around
planet Earth tonight (April 4),
many amateur astronomers will set up their telescopes
for a 24-hour global star party.
The planetwide star party is part of
100 Hours of Astronomy
(100HA), a project of the
International Year of
Astronomy 2009.
To join the party, members of the public can
find a nearby organized event or planned webcast by consulting
the schedules on the
100HA website.
What could you see through a telescope tonight?
For starters, a bright Moon will shine in the evening sky,
offering telescopic observers spectacular views of
impact craters,
mountains, and
lava-flooded mare.
Tonight's other celestial targets include the
crowd pleasing planet Saturn surrounded
by its own moons, its rings tilted
nearly edge-on.
