ANIMATION OF DAY & NIGHT

The Length of Planet Earth's Day and Night Web site is an excellent way
to explain for changes in daylength with season. The flash animation
depicts the seasonal variation in the circle of illumination viewing
from above the north pole.  An inset shows the earth's revolution
around the sun.  To view it, visit

BLACK HOLES: GRAVITY'S RELENTLESS PULL

Black holes are places where ordinary gravity has become so extreme
that it overwhelms all other forces in the Universe. Once inside,
nothing can escape a black hole's gravity -- not even light.

The Space Telescope Science Institute's Office of Public Outreach has
created a special feature on Hubblesite to provide an in-depth look at
the nature of black holes. The site includes various interactive
multimedia activities and experiences such as Journey to a Black Hole
(fast internet connection recommended). There is also a black hole
encyclopedia that presents the site's contents sorted by topic. Visit

PLANETARIUM ON YOUR COMPUTER

Stellarium is a free open source planetarium for your computer. It
shows a realistic sky in 3D, just like what you see with the naked eye,
binoculars or a telescope. The program includes over 120,000 stars from
the Hipparcos catalog; images of nebulae; a realistic atmosphere,
sunrise and sunset; the planets and their satellites.

New multilingual versions have been released for Windows and Linux
systems. A Mac OS X version  is pending. To download a copy, go to
