Mars appears in the west-northwestern sky near the star Aldebaran during May. On May 1, it is about 7 degrees to the upper right of Aldebaran. Look for it about an hour after sunset low in the sky. You’ll need a good horizon to see it. It is fading in brightness and begins to set during twilight on May 11 as it heads toward a July 26 solar conjunction. It reappears in the morning sky in early autumn with a close conjunction with Venus on October 5.
