The "King of Planets," which will dominate the evening sky from late 2011 through early 2012, is a captivating sight no matter how you look at it.
The Galilean-satellite events published in Sky & Telescope's May 2008 issue are incorrect. Here's the correct listing.
As the first images are released from Messenger's flyby of the innermost planet, previous ground-based observations are proving to be surprisingly accurate.
Mercury is a rewarding challenge for planetary astrophotographers, as this amazing image by Massachusetts amateur John Boudreau demonstrates.
Binoculars and our charts are all you need to spot these twin outer planets.
Virtually any telescope will show Jupiter's four Galilean satellites and their interesting interactions with the planet or its shadow.
Not so long ago, astronomers thought only a few dozen satellites orbited the planets of our solar system. Today the total count tops 170!
Viewing the solar system¹s largest planet can be more than fun — even with a modest telescope, you can make observations of lasting scientific value.
Amateurs are observing this elusive planet more successfully than ever before; try spotting it yourself.
If you see a bright "star" not shown on your planisphere (star wheel), it's probably a planet. The planets always stay in or near the zodiacal constellations, which straddle the ecliptic (shown as a green line on Sky & Telescope's Star Wheel and a blue line on our Night Sky Star Wheel). For help in…

Never before in human history has such a golden opportunity to observe the red planet presented itself, so make the most of it with our Mars observing guide for 2003.
If you've never spied Mars's two satellites, Phobos and Deimos, the end of 2007 is your best chance for a long time. You'll need a big telescope and you'll need to know exactly where to look.
From now to year's end, our finder charts will help you locate Uranus (in Aquarius), Neptune (in Capricornus), and Pluto (in Ophiuchus).
The crescent Moon joins Jupiter and Venus in the east at dawn to create a beautiful scene on November 9th and 10th.
Until early April, all five planets that are ever visible to the unaided eye shine at once during dusk.
For the first time since 1882, Venus will glide across the face of the Sun. Here's where you'll be able to watch this rare event on June 8, 2004.
Venus is readily visible in the evening sky until late May during this most favorable apparition of its eight-year cycle.
This coming weekend, weather permitting, almost anyone with a telescope in North America (and northwestern South America) can see the shadows of three Jovian moons at once.
Clouds and poor seeing plagued much of North America on the night of March 2728, 2004, but some observers still managed to see the remarkable triple shadow transit on Jupiter.
A new, 40°-long, diffuse blue feature is currently visible at the interface between Jupiter's South Equatorial Belt and the Equatorial Zone.
If events of the past 30 years are an indication, there's a good chance that the Martian landscape may soon be cloaked by a major dust storm.
During the predawn hours of Thursday, July 17th, the waning gibbous Moon will cover Mars for skywatchers in southeastern Florida, the Caribbean, and parts of Central and South America.
