Curious: did you even look at that paper? Here http://arxiv.org/pdf/1506.07085v4.pdf … or http://iopscience.iop.org/article/10.1088/1538-3873/128/962/045004/pdf … ? Search for the word "venus".

Did you read the context of where I mention Venus in my article?

By your logic, the Sun is inside Earth's orbit. So saying Sun instead of Venus would be perfectly legit to make the point? /2

It's pretty self-evident that the sun is not visible in the night sky.

Self-evident indeed. So isn't Venus, for most of the night, except for just before sunrise and after sunset. Guess why? /1

Yes, but it is visible at times. Nathan is saying Amy said nothing within Earth orbit can be seen in night sky.

No way to verify and I'm sure Amy would remember exchange differently. And Nathan used Venus as a counterexample.

It is a fact that *nothing* inside Earth's orbit is seen in the night sky except for few mins after sunset & before sunrise.
