In most years, Fomalhaut appears solitary. In 2019, however, Fomalhaut has company in the evening sky. The bright planets Jupiter and Saturn are up there, too, pointing the way to Fomalhaut on the sky's dome.
September 22 is the equinox. The word means "equal night." Days and nights are nearly equal now at the equinox, but not quite. Here's why. Also, we've got a new word for you, "equilux." It's the word for when day and night are, in fact, equal.

As darkness falls these next few evenings - September 3, 4 and 5, 2019 - watch for the waxing crescent moon traveling in front of the constellation Libra the Scales. The moon heads eastward, as it always does in its orbit around Earth. It'll sweep past the star Zubenelgenubi, then head toward the red star Antares and bright planet Jupiter.
We had a new moon on August 30, 2019. A number of people around the world are likely to catch the whisker-thin waxing crescent after sunset August 31. On the evenings after that, the moon will stay out longer after sunset and become easier to see.
