What camera are you shooting with ?
Often exposures to reveal the stars are long enough to produce trails - google 'equatorial mount'
I'm building a computer controlled one here in AK soon

Its just that their virtually infinite brightness is reduced to nothing due to their virtually infinitely small viewable section here on earth (one exception being our very own sun), most stars sections (a literally astronomical proportion of them) when focused are so small that they fall within a photosite or silver grain area of your frame, because of this you need to accumulate exposure over time... This same time will cause the houselights to blow out (even though they are no where near as bright as the stars)
I must look up the answer to why the sky appears black however - something to do with universal expansion or something
