Astronomy magazine podcast: Mars at opposition

Senior Editor Rich Talcott lets you know how to observe Mars at its best.
December 19, 2007
Christmas Eve will bring a lot more than Santa this year. Mars shines brightest and remains visible all night when it reaches opposition December 24. That night, the Red Planet shines brighter than any star; only the Full Moon and Venus will outshine it. An opposition occurs when Mars lies opposite from the Sun, becoming fully illuminated. Mars' oppositions happen roughly every 780 days.

In this week's show, Senior Editor Rich Talcott lets you know how to observe Mars at its best.
