QUOTE The Hubble images are a few pixels wide. But through a technique called dithering, multiple, slightly offset pictures can be combined through computer-image processing to synthesize a higher-resolution view than could be seen in a single exposure. "This has taken four years and 20 computers operating continuously and simultaneously to accomplish," says Buie, who developed special algorithms to sharpen the Hubble data. http://hubblesite.org/newscenter/archive/r...s/2010/06/full/ It's from ACS data. WFPC3 observations planned. Is Pluto a lot closer than the other big Kuiper objects? It would be neat to see those, too. |

Yes, Pluto is the closest of the big ones and the second biggest known, which is why it was discovered so long before all the others.

I added the new map to my copy of Celestia, and here are some sample views from New Horizons encounter:

The surfaces changes between 1994 and 2002-03 are quite dramatic.
We obviously have a quite dynamic little world out there.

It would be nice to add into that animation the earlier eclipse-based albedo map.

Here's a fascinating "behind the scenes" article on how these neat new images of Pluto were produced:

Marc Buie has posted the full paper, including the Charon map and the comparison with the mutual events maps from the 1980s.

Any plans for viewing Pluto between now and pluto encounter by Hubble?

Yes - it says so in the press release, last sentence.
http://hubblesite.org/newscenter/archive/r...s/2010/06/full/ The next attempt will be in the spring/summer - http://www.stsci.edu/cgi-bin/get-visit-sta...rkupFormat=html Here is the abstract - http://archive.stsci.edu/proposal_search.p...st&id=11556 -------------------- |

Anybody know at what range and how long before closest approach New Horizons will match the resolution of these maps?

QUOTE (Stu @ Feb 5 2010, 06:57 AM)  Pluto has a yellow-orange what..?  Ahh, that explains it. We're seeing tribal villages, and the movements on the surface correspond to migration patterns, perhaps due to a nomadic way of life. -------------------- -- Hungry4info (Sirius_Alpha)

Thanks. (I think I heard Mike say that future Hubble images are not expected to improve the map resolution, though they will track changes.)
