Sky This Week - Thursday May 21 to Thursday May 28

The New Moon is Saturday May 23. Venus is sinking lower in the evening twilight becoming harder to see as Mercury rises out of the twilight. On the 22nd Mercury and Venus are closest and on May 24 The thin crescent Moon, Mercury and Venus make an attractive, if difficult to see, triangle low in the twilight. Three bright planets are visible in the morning skies. Jupiter dominates the morning skies near Saturn and the pair are above Mars. Jupiter and Saturn are now rising before midnight and visible in the late evening.

The New Moon is Saturday May 23.
