There is a small buzz online, claiming that NASA has a patent that imitates the sun, and are likely using it to create a false sun (or a 2nd sun), seen from the earth.
Artificial Sun
(it's a lengthy video, much is guesswork....)
Here is one of the patents mentioned, from 1966.... http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19710020816.pdf
(see patent lines 18 to 35)
I spent an hour researching this, and this is what I found, and wrote about it.....

Anyone care to add or correct this explanation ?The old 1960's NASA sun simulator STAR (nickname), was for an environmental test chamber right here on earth, to simulate the sun found in space. It was used to test: electronics, metal and plastic materials, lenses (glass and plastic), and anything else that would be subject to outer-atmosphere solar ray testing. It was for simulating the "outer space" sun....here on earth, in a person-sized chamber that could be vacuumed of air... It's still done today with more modern methods and light sources
