I noticed that the (bear with me on the terminology here because this is Uranus & everything's tilted 98 deg) 'north polar' area seems depressed as well 'above' the large crater in the crosseyed pair.

Interesting little world among many there, well worth further investigation. Sure hope I live that long.

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.

Thanks!

I see many topographic details, but one must be careful about interpretation. For example some "details" can be simply artifacts from reseau marks.
But I made simple comparison with Titania topography obtained by photoclinometry from article
Large impact features on middle-sized icy satellites from Moore, Schenk, Bruesch, Asphaug and McKinnon (Icarus 171, 421-443)
and it looks very similar to their DEM of Gertrude regio.

This is cross-eye "stereo quaternion" made by same method. First pair is in principle same as my first cross-eye of Titania,
others are new for a little different perspective.
Two outer images are "original" (processed) images from Voyager, others are synthetic.
Edges are distorted, but I preserve them now for completeness (in cross-eye images, their aren't so disturbing).

EDIT: Anaglyph version is here.

Wow! The anaglyph version looks almost like a hologram. The images appear to rotate slightly when you move your head from side to side. Beautiful work!

some new, cool infrared images of Uranus and Neptune

I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

One thing that got mentioned on twitter but not there was the obvious eccentricity of Uranus's rings. Pretty neat.

For anyone interested .I put together an artistic extrapolation based on the Keck and Hubble images

I just found the following information:
Professional observers reported a very bright cloud on Uranus, using the Gemini telescope. They need amateur confirmation:

http://www.universetoday.com/90393/observi...ranus-reported/

The discovery was made over a month ago and it's strange that there is almost no mention to it in media (and even on the web) !
Best regards,
Marc.

Dear all,

I just bought the book "Uranus" edited by Bergstrahl, Miner and Matthews. With over 1000 pages, it is still "the bible" of the Uranian system. There are many data, pictures, mosaics and schemes not found anywhere else. Looking at the maps of the moons, I realized that there were still many important features without a name (especially on Miranda).
Just few examples:
the 340 chasma,
the South Pole Tangent chasma,
the Arden Concentric chasmata.
There are also many other interesting linear features as well as craters and basins deserving a name (not only on Miranda).
Most of the names were given in 1988. Three others were added in 1997.
I'm wondering about the rules to decide to name features. Will we have to wait the next mission to the Uranian system (20 years from now at best) to get some new ones ?
Best regards,
Marc.

Check out this website:

http://planetarynames.wr.usgs.gov/

You will see lists and maps of names throughout the solar system (only lists for the Uranian satellites so far), but also a lot of background information including naming themes, and a form for suggesting names.

You can suggest names, as anyone can, but typically they are not accepted unless there is a compelling reason such as a new mission (look for new names soon in the Gale crater area on Mars), a new scientific study (recent names on Mars include small dark-rayed craters, for instance, based on a recent study) or a forthcoming geological map.

I have made suggestions in the past, but never had any adopted!

Phil

Greetings. Here are the present versions of my Uranian satellite maps with feature labels, starting with Miranda and Ariel:

Pixie Chasma looks a bit ambiguous to me, is it the feature north or south of the label?

Little surprised that no one has commented on this:

http://www.astrobio.net/pressrelease/4694/...psed-from-earth

Very cool. Been waiting for something like this for a long time.
If the phenomena are transient presumably people will now be able to monitor more assiduously.

Neptune next?

Edit: I guess this could have gone in telescopic observations. But what the heck, its not like there are fleets of spacecraft heading out that way...
