As for me I appropriated the image of Aldebaran for that purpose. =)

Pluto looks less spherical than I expected. That's (very likely) due to oversampling and high albedo variation. To discern these effects from real deviations from a spherical shape, we'll need images from closer-up. Nevertheless Pluto may be heavily cratered; can't wait to see what these features actually are. |

JGoldader-- The faux stamp is awesome! May I use this in social media? I would be honored, sir! Glad to give back a little. I got to see Pluto through the UH 2.2m with Dave Tholen back in grad school; now that little dot is becoming a real place, thanks to you and your team. -Jeff |

Just for the record... I have tried reprojecting the latest three images to make a cylindrical projection map, but I can't get a consistent result. The bright spots don't combine as I would expect. I don't know where the problem is right now. There might be issues with limb brightening and deconvolution that are complicating matters. I hope the science team will put something out so I can see what i am doing wrong.

This is not too surprising- as we noted in the release, we are not confident of the reality of the finest details in these images (deconvolution can do funny things). Fortunately all will be clear very soon!

Thanks, John. So, folks, don't go overboard on the interpretations just yet. Wait - is that a gully?

is a detailed timeline of the observations at closest approach available somewhere? with times of the occultations and such? I have only found this "playbook" for LORRI and MVIC

No obstacles found for NH (rings, little moons...)

NASA to Hold Media Call to Discuss Surprising Observations of Pluto’s Moons
http://www.nasa.gov/press-release/nasa-to-...-pluto-s-moons/ "NASA will host a media teleconference at 1 p.m. EDT on Wednesday, June 3, to discuss the Hubble Space Telescope's surprising observations of how Pluto's moons behave, and how these new discoveries are being used in the planning for the New Horizons Pluto flyby in July." -------------------- -- Hungry4info (Sirius_Alpha)

So they are misbehaving? Releasing gas, dust? Irregular rotation or orbits?
