The art of stone balancing, which involves balancing stones on
top of one another in arrangements that appear to be physically
impossible, exploits our powerful physical expectations about
what might happen. Peter Battaglia et al. developed and tested a
model of the mental computations that underlie the inferences
that people make to understand physical scenes. Image courtesy

Just in time for Halloween, scientists at NASA combined images
of the most active regions of the sun on October 8 and
discovered something awesome — the Pumpkin Sun. Using two sets
of light wavelengths, NASA scientists were able to create the
Halloween-like appearance, making the sun look like a carved
pumpkin![/quote]

The “Potsdam Gravity Potato” Shows Variations in Earth’s Gravity

People tend to think of gravity here on Earth as a uniform and
consistent thing. Stand anywhere on the globe, at any time of
year, and you’ll feel the same downward pull of a single G. But
in fact, Earth’s gravitational field is subject to variations
that occur over time. This is due to a combination of factors,
such as the uneven distributions of mass in the oceans,
continents, and deep interior, as well as climate-related
variables like the water balance of continents, and the melting
or growing of glaciers.
And now, for the first time ever, these variations have been
captured in the image known as the “Potsdam Gravity Potato” – a
visualization of the Earth’s gravity field model produced by the
German Research Center for Geophysics’ (GFZ) Helmholtz’s Center
in Potsdam, Germany.
And as you can see from the image above, it bears a striking
resemblance to a potato. But what is more striking is the fact
that through these models, the Earth’s gravitational field is
depicted not as a solid body, but as a dynamic surface that
varies over time.This new gravity field model (which is
designated EIGEN-6C) was made using measurements obtained from
the LAGEOS, GRACE, and GOCE satellites, as well as ground-based
gravity measurements and data from the satellite altimetry.

Compared to the previous model obtained in 2005 (shown above),
EIGEN-6C has a fourfold increase in spatial resolution.
“Of particular importance is the inclusion of measurements from
the satellite GOCE, from which the GFZ did its own calculation
of the gravitational field,” says Dr. Christoph Foerste who
directs the gravity field work group at GFZ along with Dr. Frank
Flechtner.
The ESA mission GOCE (Gravity Field and Steady-State Ocean
Circulation Explorer) was launched in mid-March 2009 and has
since been measuring the Earth’s gravitational field using
satellite gradiometry – the study and measurement of variations
in the acceleration due to gravity.
“This allows the measurement of gravity in inaccessible regions
with unprecedented accuracy, for example in Central Africa and
the Himalayas,” said Dr. Flechtner. In addition, the GOCE
satellites offers advantages when it comes to measuring the
oceans.
Within the many open spaces that lie under the sea, the Earth’s
gravity field shows variations. GOCE is able to better map
these, as well as deviations in the ocean’s surface – a factor
known as “dynamic ocean topography” – which is a result of
Earth’s gravity affecting the ocean’s surface equilibrium.

enhanced) calculated from CHAMP data. Credit: GFZ
Long-term measurement data from the GFZ’s twin-satellite mission
GRACE (Gravity Recovery And Climate Experiment) were also
included in the model. By monitoring climate-based variables
like the melting of large glaciers in the polar regions and the
amount of seasonal water stored in large river systems, GRACE
was able to determine the influence of large-scale temporal
changes on the gravitational field.
Given the temporal nature of climate-related processes – not to
mention the role played by Climate Change – ongoing missions are
needed to see how they effect our planet long-term. Especially
since the GRACE mission is scheduled to end in 2015.
In total, some 800 million observations went into the
computation of the final model which is composed of more than
75,000 parameters representing the global gravitational field.
The GOCE satellite alone made 27,000 orbits during its period of
service (between March 2009 and November 2013) in order to
collect data on the variations in the Earth’s gravitational
field.
The final result achieved centimeter accuracy, and can serve as
a global reference for sea levels and heights. Beyond the
“gravity community,” the research has also piqued the interest
of researchers in aerospace engineering, atmospheric sciences,
and space debris.
But above all else, it offers scientists a way of imaging the
world that is different from, but still complimentary to,
approaches based on light, magnetism, and seismic waves. And it
could be used for everything from determining the speed of ocean
currents from space, monitoring rising sea levels and melting
ice sheets, to uncovering hidden features of continental geology
and even peeking at the convection force driving plate
tectonics.
