That brilliant “star” very low in the southwest in evening twilight is Venus. You’ll need a clean western horizon to see it. You’ll probably need binoculars to see the elusive planet Mercury just below it. As the brightest object in the nighttime sky besides the moon, the sun’s second planet is hard to miss. If it’s cloudy tonight, take heart. Venus will be visible through the end of winter. As the days and weeks pass, it will be a bit higher every night.
