Flying Into The Final Frontier

Venus has now departed from our evening sky, but two other planets remain visible low in the dusk during August. During the first half of the month, Mercury can be seen close to the horizon, while Mars is slightly higher. The Red Planet disappears into twilight by month’s end, not to reappear in our morning sky until about six months from now.

Our solar system’s two largest worlds dominate the skies this month. Saturn, already in the southeast by the end of dusk, is at opposition directly opposite the sun in the sky August 26 and remains visible throughout the night.
