Sick of Mars? Try Saturn
NASA Science News
September 17, 2003

Saturn is fast becoming an eye-catching sight in the morning
sky. Jupiter's not bad either.

September 17, 2003: It's the brightest thing in the night sky. It's
historically close to Earth. It's a wonder to behold through a telescope.
It's ... Mars.

If you've been listening to the news for the past two months you've
undoubtedly heard a lot about Mars. Mars. Mars. Mars. And just maybe,
you're getting sick of Mars. Good news: There are eight other planets in
the solar system. And this week you can see the two biggest ones.

First, try Saturn.

You'll have to wake up early to do it, about 5 o'clock in
the morning, but that's not much earlier than usual on a
school day. Look high in the eastern sky. Saturn sits in the middle of
the constellation Gemini. The planet is about three and a half times
brighter than Castor and Pollux, Gemini's brightest stars, so it's easy
to pick out.

When observing Saturn, a telescope is recommended. Not because Saturn is
dim. It's because you'll want to see the planet's magnificent rings.
They're almost twice as wide as Mars, an easy target for small
telescopes.

While you're looking at Saturn's rings, consider this: they're a mystery.
Astronomers aren't sure where they came from or how old they are. Some
evidence suggests they formed only a few hundred million years ago--a
time when dinosaurs roamed the Earth. Before then Saturn might have been
a ring-less planet. You can find out more by reading Science@NASA's "The
Real Lord of the Rings."

Next, look for Jupiter.

From Saturn, trace an imaginary line down toward the horizon. That leads
you to Jupiter--a bright "star" shining through the rosy glow of sunrise.
Jupiter has spent the past two months hiding behind the sun, but now it's
emerging from the glare.

Jupiter is five times brighter than Saturn--really eye-catching.
Jupiter's cloud belts are easy to see through a telescope, as are its
four largest moons: Io, Europa, Ganymede and Callisto. Together they look
like a miniature solar system.

Jupiter will be in the news this week because NASA
plans to crash a spacecraft into the planet on
Sept. 21st. The Galileo probe has been orbiting and
studying Jupiter since December 1995. The craft has
had some amazing adventures--dipping into volcanic
plumes on Io, flying through Jupiter's dark rings
and radiation belts. But now its thrusters are
nearly exhausted, and while ground controllers still have some control
they're going to send Galileo plunging into Jupiter where it will burn up
like a meteor.

The move is designed to protect possible life on Jupiter's moon Europa
from terrestrial contamination. If Galileo is reduced to atoms in
Jupiter's atmosphere, it will never accidentally crash-land on Europa. No
one on Earth will be able to see the impact, but it's something to think
about while you're watching the giant planet this week.

If you don't feel like waking up at 5 a.m. to see Saturn and Jupiter,
there's always Mars. It really is bright and wonderful--a joy to behold
through a telescope. And you can behold it before bedtime. Convenient.

Just remember... it's not the only planet in the solar system.

thanks Ron for your update.

THE best time to observe Saturn is fast approaching. It is getting
high in the sky before sunrise when you have the best chance for
exceptional seeing. Also the shadows of the rings on the planet, and
the plantet on the rings give it a 3D look.

they had a neat article (a bit dated) about the facts in Harry Potter and the
moons of Jupiter too. Some good reading, although I couldn't seem to get the
audio to play.

That depends on what one means by the word "fast". Opposition is New Year's Eve!

Cool. Orion is scheduled to ship my new 10" Dob September 30th, so I'll have
a good view from here. ;-)
