These 8 Images Of The Cosmos Will Stop You In Your Tracks
http://www.businessinsider.com/amazing-astronomy-photographs-2014-11The aurora borealis in the image below, taken by Yuichi Takasaka in 2011, are a cosmic phenomenon produced when energetic particles in space interact with gas particles in Earth's atmosphere that emit light as a result. Star trails, which cameras capture using long exposure times, are also visible.
In this image, US-based Warren Keller turned his sights toward the constellation Orion. Both the Horsehead and Flame nebulae, pictured here, are located about 1,500 light years from Earth.

(b)the first one is a very saturated exposure, and not nearly among the best of the aurora borealis,
(c)the one in the link is a nice contextual view of the Horsehead Nebula and surrounding regions, but why didn't you include it instead of just linking to it?
and (d)the one of Earth appears to be a projection mosaic from a number of lower-altitude satellite imagery, and is not an actual singular photograph from the apparent altitude. You can kind of tell the difference between a projection mosaic and a photograph.
Here's a photograph, from Apollo 12:

See the difference?
The latter isn't "fake," it's just not what you would see with your own eyes at that altitude. It's more of a data representation than a photograph.

"There Might be Civilizations in the Middle of Cold Dark Space Without a Milky Way" -NASA
“There might be people living out there, out in the middle of cold dark space, that don't have a Milky Way,” says Harvey Moseley, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Astronomers have spotted a faint cosmic glow, unseen until now, that may come from stars that float adrift between galaxies. The discovery suggests that as many as half of all stars in the Universe lurk outside galactic boundaries.
