SHOOTING STARS
WELL, NOT REALLY, THEY’RE METEORITES.

Ahh, meteors, not only a model of mums’-
shopping-car made by Ford in the 1980s, but
also the catch-all term to describe shooting stars.
Against a sea of black, you’ll see them launch,
catch your eye for a second or two, in a blaze of
green or purple and then disappear spectacularly.
What we are witnessing in these situations is not
the end of the billion year life of some distant sun.
But rather bits of rock hurtling through space. And
where did these aming rocks come from? They’re
mostly debris that’s broken free from bigger rocks
(asteroids) and from comets.
They usually travel in clusters, which can look like
showers from the ground, and, when they come in

contact with our atmosphere, they ame up and
zzle out.
The Australian bush has long had a rep for
being the peak place in the world for catching
these shows. Especially in the tropics, because the
closer you get to the equator the more brilliantly
shooting stars become visible, especially if you’re
facing to the north between midnight and dusk.
The two major showers that bring stargazers out
of the woodwork, and lying down in open spaces,
are the Orionids in October, and the more prolic
Geminids, which appear two months later during
summer school holidays.
