Why are Jupiter and Venus so bright in the night sky?

Well, darling, Jupiter and Venus are shining like diamonds in the sky because they are the two biggest show ponies of our solar system. They're so darn bright because they reflect a good amount of sunlight back at us lonely souls on Earth, making them stand out like a Kardashian at a library. So, next time you look up and see those two dazzling stars, just remember it's all about that sunlight reflection game.
