I've been to Niagara Falls more times than I can count, and it is ALWAYS simply incredible. I've stood by the falls for hours, until soaked by the spray. I've also been there when the smaller section (The American falls) was frozen.
Yup, HIGHLY doubt this is a real picture even though it is said to be. makes me sad! Why can't the real outer space be as colourful as a fake picture like this? :/ --- if it's any consolation, this could be the sky on another planet.
