From Accuweather:
A rare planetary alignment that won’t occur again for nearly two decades has taken shape in the night sky, and while it will remain visible through the end of June, viewing the spectacle may be tricky and could require losing some sleep.
Mercury, Venus, Mars, Jupiter and Saturn have lined up in the early morning sky, a planetary procession that can be seen above the eastern horizon every morning through the end of June. This long-lasting event will give early risers plenty of opportunities to enjoy the sights of the planetary quintet.
