In an effort to provide both sides of the argument let me post some no replys found on them interwebs
No the sun cannot be seen in outer space, and it has been proven
The sun is NOT visible in space as it emits no visible light only particles which have to interact with matter before they can be detected!
As an experiment try your tv remote control pointed at your eyes and press any button, you see nothing because it is transmitting infra red light. Repeat the same experiment using your mobile phones camera as your eyes and 'hey presto' you see it!
No medium no light!
This also explains all those Apollo moon pictures with no stars visible! You also never saw an image of the sun from the moons surface or any where else did you!
It is because the glare of the sun and the moon's surface is very bright, They adjust the camera to make the whole picture darker so the moon wont be just white this make the very dim stars not does not appear in the picture.
