Look to the western sky about 30-90 minutes after sunset on April 19 for a fleeting but incredible sight, as the razor-thin crescent moon shines above the Pleiades open star cluster and Venus in the early spring sky.
The upturned 11%-lit waxing crescent moon will shine approximately 20 degrees above the western horizon — the width of two clenched fists held at arm's length — just two days after the new moon on April 17.
