Intriguing. I had no idea the MarsRover had a lens that could take that Jupiter shot.

I was thinking the same thing when I first saw these pictures, Dave; Matter of fact, I'm still a little vague on which one of those objects is Jupiter, and which one is Venus; as anyone who has had astronomical telescopes and has spent a lot of time looking at Solar System objects knows, because Venus is so much nearer to the Sun than Earth is, anytime you observe the setting Sun drop below the horizon, Venus will be app. 30 degrees above the horizon, so observing Venus must be done within about 2 hours after Sunset, or within a few hours after Sunrise. Because of that fact, seeing Venus from the perspective of Mars has me completely "mixed up"!
Also, I sure wish that whoever put those pictures on the internet would have furnished a few technical details with them; at a bare minimum, I think they should have listed what space probe made the photos.

Gitzo - your comment led me to do a search of the first shot with images.google. It turns out that one was taken by the Cassini spacecraft about 6 million miles from Jupiter:

A rough calculation shows Mars never gets closer to Jupiter than 300 million miles.
And here's a story about the second image (which is apparently not real): http://blogs.discovermagazine.com/badastronomy/2012/08/10/an-unreal-mars-skyline/#.U31Y1dKcJtA
Would have been pretty spectacular.

Dave; Thanks for the link to Discover Magazine / Bad Astronomy! I just spent 30 enjoyable minutes reading all of the replies from the incredibly diverse assortment of individuals; apparently that image was originally created by the planetarium software, "Starry Night"; after being "shared" hundreds of times on social media, the copyright credit was lost; (very interesting ). ( Some very smart people on that website! )

Below are two links to NASA's website for sharing photo from the missions of the New Horizons space probe and the Cassini space probe mission

Some people have questioned the visual reality of the second picture:

Whether real photograph or computer-aided, it is a very impressive image.
