Eye on the Night Sky
Monday, April 20, 2026
Today:
Just after the sun has set, at around 7:45 PM, Venus, will appear low in west. Venus is the brightest of all the planets in the night sky, bright enough to muscle through a lot of twilight. As the twilight fades its apparent brightness will increase, but it won’t be around for long. Even assuming a flat horizon, it will set in the west-southwest at 9:55 PM, parting company with the brightest objects that remain: The crescent Moon, still up in west-southwest, and Jupiter, about halfway up in the west.
