Look at the bright center of the Galaxy for the last time this year

Science: The galaxy is always visible in the night sky, but it’s only prominent between April and October in the Northern Hemisphere. This week is a good time to take a last look at the bright star fields of Sagittarius and Scorpius. You should be at a dark sky destination, such as a Dark Sky Place or any location that looks dark on a light pollution map. As soon as it’s completely dark, look south. You’ll see the galaxy’s center, its brightest part, close to the horizon, with a stream of stars thinning out as it passes over your head through Cassiopeia, a constellation of five stars shaped like the letter W. You’ve just seen the galaxy’s Perseus arm.
