Jupiter will reign as king of the night sky on Sunday (Jan. 5), visible all night long as it reaches opposition. Here's how to see it.

Early risers will have an opportunity to see the moon move through the sky on Christmas Day and throughout the week.

Now that autumn is fading into winter, the beautiful winter Milky Way is coming into view in the eastern sky.

This week in the hour before sunrise early morning stargazers will get a double treat: the planet Mercury and two special comets.

The moon will pass just north of the planet Venus tonight (Nov. 6), making a pretty pairing in the southwestern sky, weather permitting.

This week marks two celestial events characterized by cosmic objects that are either far apart or very close.

As Earth moves in its orbit around the sun, new constellations are revealed in the east as the old ones disappear into twilight.

The moon will dip through part of Earth's shadow in a partial lunar eclipse on Friday (Oct. 18), but it may be tough to see for skywatchers in North America.

Three of Jupiter's largest moons will cast their shadows simultaneously on the planet below them creating three solar eclipses at the same time: a rare cosmic event.

The next few nights are the best times of the month to observe the surface of the moon with telescopes, binoculars or even your naked eye. Here is how to see it.

Three asteroids are visible in the august night sky, but you have to know how to see them.
