Comment about the artwork...
One thing I never get: why does the artwork which is shown in these articles always show a scenery which is pretty much unlikely?
Take this one, you see a rather big planet right up the sky. Even though the star they orbit is comparable to our sun in size and the distance idemditto. So there's no way you'd get to see the sun as shown in the image shown in the article, yet here we are.
Now, I know that those images make for much more spectacular stuff and it may even do a much better job at triggering one's imagination. But still... why can't it never be an imagine which pictures a more probable (realistic) scenery?
