A NOTE FROM FRASER... WATCH THE LEONID METEOR STORM, NOVEMBER 18TH!
I want to give you some advanced warning, because if you miss this year's
Leonid Meteor Shower, you'll probably want to kick yourself. During the
week before and after November 18, the Earth will pass through the trail of
comet Tempel-Tuttle and be pelted with hail of sand-sized material. As the
particles burn up in the atmosphere, we see streaks of light in the sky
This year is supposed to be special, with astronomers predicting anywhere
from 800 (North America) - 8,000 (Australia) meteors visible per hour at
the storm's peak - on November 18th. I don't know if you've ever seen 8,000
meteors an hour, but I sure haven't.
Astronomers have made inaccurate predictions about meteor storms in the
past, and it's entirely possible that this one could be a dud, but just to
be safe, make sure you include some time outside in your plans for Sunday,
SPACE.com has put together a handy chart listing meteor shower predictions
- take them with a grain of salt, though.

ODYSSEY'S FIRST IMAGES RELEASED
NASA's Mars Odyssey spacecraft has delivered its first image of the Planet
Mars. The picture is a thermal infrared image of the martian southern
hemisphere that captures the south polar carbon dioxide ice cap at a
temperature of about -120 C. The spacecraft was approximately 22,000 km
away from Mars' south pole, so future pictures (when the spacecraft is in a
tight orbit) will show a much higher resolution.
HUBBLE REVEALS ULTRAVIOLET GALACTIC RING
A new photo taken by the Hubble Space Telescope shows how a galaxy can look
completely different when viewed in ultraviolet light. This image of barred
spiral galaxy NGC 6782, reveals a ring of hot stars around the centre of
the galaxy. Astronomers believe this hot-star area is created when gas and
dust bunches up around in the middle of the galaxy, creating stellar
