IF YOU ever thought skywatching was too complicated, then we’ve got an event
for you. And it lasts through the end of the year.
With or without a telescope, the giant planets Jupiter and Saturn make
skywatching simple and rewarding by hanging close, bright and long in the night
sky. Saturn is the brightest it has been in more than two decades.
Opposition? Wha?
A neat feature of celestial alignment makes all this possi ble: Jupiter and
Saturn each reach their "opposition" during November.
What is opposition? If you could view the solar system from above, you’d see
Earth racing around the Sun on an inner track, more quickly than the gas giants.
When our planet "catches up" with Jupiter and Saturn, it sits squarely between
them and the Sun.
"At opposition, a planet generally rises at sunset, is high in the south at
midnight, and sets at sunrise," explains Kevin Conod, astronomer at the Newark
Museum’s Dreyfuss Planetarium in New Jersey. "Opposition is also the point at
which a planet is closest to Earth. Therefore it appears larger and subtle
features can be easier to view."
Jupiter’s brightest
So to see Jupiter and Saturn, all you have to do is go outside and look up.
And with a pair of binoculars, more surprises await.
"Many people are surprised that the moons of Jupiter are visible in
binoculars," Conod said. "You can watch them change position in a surprisingly
short amount of time."
The moons appear as small pinpoints of light, like tiny stars.
A small telescope will also resolve some of Jupiter’s colorful cloud
features. A larger telescope can reveal Jupiter’s Great Red Spot and the Cassini
Division, a dark band dividing the major rings of Saturn, as well as a handful
of Saturn’s moons.
"Both planets will remain prominent in the night sky throughout November and
December," says James White, executive director of the Astronomical Society of
the Pacific. "Jupiter is by far the brightest object in the southeastern part of
the sky in the early evening. Saturn...lies to the upper right of Jupiter in the early
evening."
