Another pale blue dot: On April 11, 2014 ISS observed Uranus as it appeared near Saturn's F ring!
Right after the raw images came in, Ian R and I put together this RGB color composite (we chose the set of raws with longer exposures to make Uranus more visible): -------------------- Val Klavans

I have to say that Val did a great job of employing this composite for outreach purposes, disseminating it via the likes of Facebook and Twitter to a very positive reaction.

Just out of curiosity, does anybody know what the apparent magnitude of Uranus was from Cassini in this shot? I can't see it ever getting brighter than, say, 4.5 or so even during the most favorable possible opposition.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Dimmer than Uranus as seen from the earth - approx 6.7 according to Horizons ( http://ssd.jpl.nasa.gov/ ) - because right now Saturn and Uranus are on opposite sides of the solar system |

Taken by Cassini's wide-angle camera on April 4th 2014, this great view of Saturn in infrared:
I used two images (W00088137 and W00088136) for the red and blue channels, creating a fake green channel by averaging the two images. I then used this excellent image from a JPL article to superimpose my colour image over.
