Enough data was returned to start making true color photo!
Just some photos.Mostly astronomy pics but other as well.Movie photos etc.The Walkingdead Dead and etc!

One of the closest-ever views of Pluto
Going where no other spacecraft has gone before,
New Horizons has sent back some pretty stunning images of Pluto--from
endearing heart-shaped features to giant ice mountains. And the images just keep getting better.
On Friday, NASA released the first batch of the
sharpest-ever images of the former planet. The view above shows the
region where the flat Sputnik Planum meets the al-Idrisi mountains. It
has a resolution of 250-280 miles per pixel, "revealing features less
than half the size of a city block!The new details revealed here, particularly the crumpled ridges in the rubbly material surrounding several of the mountains, reinforce our earlier impression that the mountains are huge ice blocks that have been jostled and tumbled and somehow transported to their present locations
More stuff ! Yes More!
A Japanese spacecraft should be orbiting Venus now, if all went according to plan Sunday (Dec. 6).
The Japan Aerospace Exploration Agency's Akatsuki probe fired its small attitude-control thrusters for 20 minutes Sunday evening in a second and final attempt to enter Venus orbit. Akatsuki's first try — which came exactly five years earlier, on Dec. 6, 2010 — failed when the probe's main engine conked out during the orbit-insertion burn, sending the spacecraft sailing off into deep space.
It's too early to know if Akatsuki is indeed circling the second planet from the sun, the spacecraft's handlers said.
"The orbiter is now in good shape," Japan Aerospace Exploration Agency (JAXA) officials wrote in a mission update Sunday. "We are currently measuring and calculating its orbit after the operation. It will take a few days to estimate the orbit; thus we will announce the operation result once it is determined."
The $300 million Akatsuki mission, whose name means "Dawn" in Japanese, launched in May 2010 to study the clouds, weather and atmosphere of Venus, with the aim of helping scientists understand how the planet ended up so much hotter and less life-friendly than Earth. (Surface temperatures on Venus are hot enough to melt lead.)

A Force from Empty Space: The Casimir Effect
This tiny ball provides evidence that the universe will expand forever.
Measuring slightly over one tenth of a millimeter, the ball moves toward a
smooth plate in response
to energy fluctuations in the vacuum of empty space.
The attraction is known as the
Casimir Effect, named for its
discoverer,
who, 55 years ago, was trying to understand why fluids like
mayonnaise move so slowly.
Today, evidence indicates that most of the
energy density in the universe
is in an unknown form dubbed
dark energy.
The form and genesis of dark energy is almost completely unknown, but postulated as related to
vacuum fluctuations similar to the
Casimir Effect but generated somehow by space itself.
This vast and mysterious
dark energy
appears to gravitationally repel all matter and hence will likely
cause the universe to expand forever.
Understanding vacuum energy
is on the forefront of research not only to
better understand our universe but also for
stopping micro-mechanical machine parts from sticking together.

Phobos: Doomed Moon of Mars
This moon is doomed.
Mars,
the red planet named for the
Roman god of war, has two tiny moons,
Phobos and
Deimos, whose
names are derived from the Greek for Fear and
Panic.
These martian moons may well be captured
asteroids
originating in the main asteroid belt between Mars and
Jupiter
or perhaps from even more distant reaches of the Solar System.
The larger moon, Phobos, is indeed seen
to be a cratered, asteroid-like object in this
stunning color image from the robotic
Mars Reconnaissance Orbiter,
recorded at a resolution of about seven meters per pixel.
But Phobos
orbits so close to Mars - about 5,800 kilometers above the surface compared to 400,000 kilometers
for our Moon - that gravitational
tidal forces
are dragging it down.
A recent analysis
of the long grooves indicates that they may result from global stretching caused by
tides --
the differing force of Mars' gravity on different sides of
Phobos.
These grooves may then be an early phase in the
disintegration of
Phobos into a ring of debris around Mars.
Mars will look like this within 30 million years (-/+) My guess they would be dark,some people put bright Saturn type of ring but they are made out of ice.Mars ring system would be made out of rocks.
