Stargazers, get ready! Starting April 23, 2022, Saturn, Mars, Venus, and Jupiter will form a straight line behind the crescent Moon. The perfect alignment will provide earthlings a relatively rare opportunity to see multiple planets in the sky with the naked eye. Experts say the celestial treat can be best observed by gazing southeast — in the direction of the sunrise — about an hour before the Sun comes out.
