The Milky Way
September 2010 :
This month, we explore the galaxy most of us are familiar with – the Milky Way. Many astronomers regard the Milky Way, viewed with the unaided eye on a dark, moonless night, as the most awe-inspiring heavenly sight of all. During late summer, it arches overhead, from Cassiopeia to our north, through Cygnus above, then down to Sagittarius on the southern horizon.
Studying the Milky Way with a standard telescope is akin to exploring the Mississippi River by placing a drop of its water under a microscope. You’ll do better by sailing the Milky Way with the most practical vessel possible – binoculars.
On an evening and location (preferably one that affords an open sky) where dark skies prevail, set up a reclining lawn chair or lay down a blanket. Relax and direct your binoculars towards Cassiopeia, the departure point for your “cruise.” Take your time and enjoy the scenery. Maintain a course through Cygnus and onward to Sagittarius. Along the way, you’ll encounter a dazzling cosmic vista – myriads of stars interspersed with an occasional cluster or nebula.
When finished, begin again. Unlike a traditional ocean cruise, this one doesn’t cost a penny and the scenery is far more spectacular.
