If it’s clear this evening and you have a unobstructed view of the western horizon, go out and look for Venus and Mercury. Venus is, by far, the brightest thing in the sky and should be obvious. Mercury is the fainter star to the lower right of Venus. Though Venus will be visible in the evening sky for the next few months, Mercury will only be easily observable for the next week or so.
The image below was taken with a Canon EOS XSi in the early evening (April 9).
