Venus and Uranus form a very close conjunction in the evening sky tonight. Brilliant Venus is easily seen in the twilight, but you probably won’t be able to see fainter Uranus with just your eyes unless you have fine eyesight and clear, dark skies free of light pollution. With only five arc minutes between the pair, both planets should easily fit within within the same field of view when observed with binoculars or a low powered eyepiece.
