I tend to disagree that Saturn can be seen with naked eye (with my little knowledge about astronomy).
You can walk outside tonight and see venus very easily. At least on my part of the world. I been looking at it for a month. It's the brightest thing in the sky.
Definitely worth witnessing I'm sure. Any time I hear about any event like this I try to capitalize on it. Its always so worth the evening outside.
very nice picture I don't know much about astronomy, but it looks impressive seeing the 5 planets lined up like this
