    It should be noted that the artists chose to depict only the probes that are still in contact with Earth. Voyager 1 and Voyager 2 are still transmitting and are the farthest probes from Earth but while New Horizons is travelling far faster than any probe built before it it's still nowhere near as far from Earth as two probes not depicted here: Pioneer 10 and Pioneer 11.

    Both Pioneer probes were launched in the early-'70s; NASA's last contacts with Pioneer 11 and Pioneer 10 were in 1995 and 2003 respectively. Pioneer 10 was the first probe to ever pass through the asteroid belt and fly by Jupiter, and Pioneer 11 was the first past Saturn. Though their power systems no longer function (they ran out of fuel, as both Voyager probes will in about 10 years) they still silently carry on part of their mission. They were the first probes designed to achieve escape velocity from the solar system, and as such were the first to carry a message from Earth to whomever may find them:

    This is the dwarf planet Ceres, located about 3.4 AU from Earth right now. It's the largest body in the asteroid belt between Mars and Jupiter, and the probe Dawn will begin orbiting it on Friday after its seven-year-long journey to get there. This animation was created by NASA from a composite of several images Dawn's camera took last month.

    No one's really sure what the two bright dots are. About eleven years ago the Hubble Space Telescope took pictures of Ceres and the bright spots were distinguishable but it wasn't until Dawn began approaching that it was discovered the one blurry spot in the Hubble photograph was really two discernible spots. Some believe it may be cryovolcanic activity: volcanoes spewing water, ammonia and methane rather than magma.

It will orbit Ceres for the foreseeable future, long after it runs out of fuel.

    Give yourself a moment to think about what's pictured below.

    Figured it out? Curiosity took the picture on the left about a year ago: it's a picture of Earth, from Mars. The picture on the right is a picture of Mars from Earth.

    Spacecraft Data Suggest Saturn Moon's Ocean May Harbor Hydrothermal Activity

    Things to know:
    • Cassini finds first evidence of active hot-water chemistry beyond planet Earth
    • Findings in two separate papers support the notion
    • The results have important implications for the habitability of icy worlds

    NASA's Cassini spacecraft has provided scientists the first clear evidence that Saturn's moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities.

    "These findings add to the possibility that Enceladus, which contains a subsurface ocean and displays remarkable geologic activity, could contain environments suitable for living organisms," said John Grunsfeld, astronaut and associate administrator of NASA's Science Mission Directorate in Washington. "The locations in our solar system where extreme environments occur in which life might exist may bring us closer to answering the question: are we alone in the universe."

    Enceladus is Saturn's six-largest moon.

    New Horizons will fly by Pluto this summer, after its nine-year journey to get there. It will be the first time a probe has ever passed close to Pluto. As such it will be the first time relatively clear photographs will be taken of Pluto, and of its largest moon, Charon.
