nothing is blacked out. the earth is so much brighter than stars in the background, so you don't see them in this exposure.
Also, earth is much, much bigger on this picture than Moon ever is, apart from the time it's size is exaggerated by being close to horizon, but it is the effect of the atmosphere; there is no atmosphere on the Mooon, hence no "magnifying" effect when close to horizon.
oh please, you didn't just try to explain that picture, it has been proven to be a hoax so many times...

Maybe you aren't clever enough to evaluate the evidence yourself, so using insults is the only way you can contribute.
If you look at the linked video, you will see how they took the photo of the Earth used in the composite.
It won't be long before these faked images are acknowledged within a historical timeline of American Politics.
In 1963, John F Kennedy was assassinated in a political coup. This was covered up, and still is to this day. There is credible evidence that KKK members were among the conspirators involved.
A year before the moon landings, Martin Luther King was assassinated, as he tried to stand up for racial rights.
In 1969, the Moon Landings were propaganda used by a corrupt nation state to establish a sense of 'National Unity', in the middle of the Vietnam war.
In 2001, the 9/11 attacks occurred, this was a 'false flag' event used by this same corrupt nation state to justify more wars.
Now it's 2015, and the same tricks are still being used, however, we can use the internet and study history and prove ourselves smarter than that.
Now while you think about this, ask yourself why there haven't been any more manned missions to the moon since 1972.
