Strange Lights on Dwarf Planet Ceres have Scientists Perplexed
Holy crap, we have a artifact! Now try to convince me otherwise. Unless NASA is pulling a bogus routine - go for it - i dare you - this is an unnatural reflector that is unlikely to be a sheet of ice. It also appears to be unique and large as well. There is nothing else special and it is also centered in the crater.
Go for it - find me a bullseyed double impact anywhere in the solar system. I does not happen. Thus we already have two problems. The second object or sheet appears to be one diameter away from the first and to be perhaps a tenth as large. Do we need any more intelligent order here?
The only possible natural explanation will be a ice volcano with a secondary run off producing the second object. It is still profoundly unique. It is possible we are looking at an impact crate produced by an ice meteor of which we so far know none.
Certainly curious.

Strange lights on dwarf planet Ceres have scientists perplexed
A dwarf planet is shining two bright lights at a NASA spacecraft
right now, and our smartest scientists are unsure what they are.
As bizarre as that sentence sounds, that's the situation with Ceres —
the largest object in the asteroid belt between Mars and Jupiter,
officially designated as a dwarf planet (the same category as Pluto).
NASA's Dawn spacecraft is approaching Ceres ahead of a March 6
rendezvous. The picture above was taken February 19, from a distance of
just under 29,000 miles, and shows two very shiny areas on the same
basin on Ceres' surface.
Previous Dawn images from further away showed a single light on
Ceres, which was just as mysterious. Then, to the amazement of every
astronomy geek, the one light turned out to be two — reflecting roughly
40% of the light hitting them.

"This
is truly unexpected and still a mystery to us," said Andreas Nathues,
lead investigator for the framing camera team at the Max Planck
Institute for Solar System Research in Gottingen, Germany, in a NASA statement.
"The brightest spot [of the two] continues to be too small to resolve
with our camera, but despite its size it is brighter than anything else
on Ceres."
So what could the bright spots be, other than alien castaways signaling at us with flashlights?
The most obvious contender is ice, although ice would reflect more
than 40% of all light hitting it. The difference may be accounted for by
the resolution limit of Dawn's camera at this distance. Scientists have
previously detected water vapor coming from the surface of the dwarf
planet, making ice — a more likely option.
Scientists have also suggested the bright areas could be patches of
salt. On the other hand, the location of the two bright spots so close
together may be an indication that they have a geologic origin, such as
some sort of volcanic process, possibly even ice volcanoes.
According to Chris Russell, principal investigator for the Dawn
mission, the positioning of the bright spots within the same area may
indicate "a volcano-like origin of the spots," but scientists will have
to wait for higher resolution images before making such interpretations.
Scientists don't think the spots comprise lava similar to that seen on
Earth, since that would shine more brightly.
We'll find out more as Dawn approaches Ceres next week and more
imagery comes in during the next 16 months, according to NASA. In the
meantime, here's more on Dawn and its eight-year mission:
