It's the real deal all right - a mosaic of 10 Voyager frames:
QUOTE The image shows Uranus with its ring system and the 10 innermost satellites. All but S/1986 U 10 were known at the time the image was taken, based on Voyager images taken in January 1986. Arrows at the edge of the image point to the 10 satellites. The other dots of light are background stars of the constellation Sagittarius. (If you know enough astronomy to want to look this up on a star chart, the bright star next to Juliet is Kaus Borealis, Lambda Sagittarii.) ... The new discovery image is a mosaic of 10 exposures, Karkoschka said. The exposures of Uranus had shorter exposure times than the exposures of the surrounding area containing the rings and satellites. Since Uranus is a million times brighter than its satellites, Karkoschka retained the darker planet image so the satellites would be visible. ... The colors in the image are close to realistic, he added. http://nssdc.gsfc.nasa.gov/planetary/text/...pr_19990518.txt -------------------- |

It occurs to me that with the computer and optical technology that is available now to the ardent enthusiast, and the colossal reams of data coming down and being archived, we could be entering a situation similar to the Victorian Naturalists in the 19th century. Who knows how many biological and paleontological discoveries are waiting to be made amongst the thousands of specimens filling the drawers of museums that amateur collectors gathered many years ago?
I am always in awe at the beauty (and science) teased out of older data sets by the esteemed members of this forum.... -------------------- Lyford Rome

A little off the planetary focus here, but I got a paper out of analyzing Voyager 2 UVS data of the nearby galaxy M33 taken while it was in pre-Jupiter cruise. The paper was submitted to the journal on the 20th anniversary of the data being taken (so when I said "twenty years ago" in the text, that was literal). Those data helped prepare a successful FUSE (RIP) program to look at star-forming regions in that and other galaxies, and gave me unusually tight constraints on the expected far-UV fluxes. Had I only realized the value of looking for escaping Lyman-alpha emission a couple of years earlier, before NASA Astrophysics got out of the UVS business...
