Observing

When you head outdoors tonight, take Sky & Telescope's podcast with you for a guided tour to the night sky. Learn what constellations are visible, find out where and when you'll see the planets, and catch each month's celestial highlights, from meteor showers to eclipses.
  1. Mars, in southern Capricornus, fades from magnitude –1.5 to –1.3 this last week of September, still as bright as Sirius. It shines highest in the south soon after dark and sets around 2 a.m.

  2. This month's Harvest Moon will be up early to light the night as well as act as a beacon for watching the annual fall bird migration through a small telescope.

  4. Often passed over in favor of showier sights, the constellation of the Little Horse has charms of its own. Let's saddle up and go for a ride.
