At 8:03pm on the 22nd of September you can say goodbye to Summer. "At that minute, that's when the sun is crossing the imaginary circle in the sky called the celestial equator," says Bob King. Regardless of your position on earth this Thursday, you'll be able to get a glimpse of the sun - both poles will have a view of opposite halves.
Other cosmic news of note, on Saturday morning between 5:30 and 6 o'clock, you can catch a "smiling" crescent moon rising over the eastern horizon. Tonight, the ISS will cross the sky from west to east across the northern sky. Look for it to pass near Polaris between 8:34 and 8:37pm.
