The critical factor in finding the best camera for low light photography is how it deals with light sensitivity. The ISO range determines this — the higher the ISO sensitivity, the better the camera will capture well-exposed images in darker environments.
The flip side of a higher ISO is that it brings noise into the image, so you'll also want to look for a camera with a larger image sensor (it physically takes up more space so it can capture more light) and one with fewer megapixels to mitigate the noise. This is why compact cameras with fixed lenses aren't traditionally favorites for low light photography — unless they have specialized sensors like the Canon PowerShot G1 X Mark III.
