Between Text and Image in Kandinsky’s Oeuvre
In 1938 Wassily Kandinsky published the text ‘My Woodcuts’ in the French periodical XXe Siècle. As was so often the case, when he wrote about his prints he focused largely on general artistic principles: the majority of the text is devoted to a general discussion of the need to privilege ‘synthesis’ over ‘analysis’ in both art and in life. However, he specifically referred to the album of poetry and engravings Sounds (Klänge), which had been published in Munich c.1912, as ‘a small example of synthetic work’

Frogs lying
While most croaks are honest, some are not. Some small males lower their voices to make themselves sound bigger. Their big-bodied croaks intimidate frogs that would beat them in a fair fight.

Giotto and the comet
This fresco, painted sometime between 1304 and 1306, features an accurately represents a comet above the Nativity stable. The fresco's realistic potrayal strongly suggests that it was based on the artist's first-hand observation of the comet Halley during its appearance in the skies over Europe in Oct. 1301. Almost seven centuries later the spaceprobe "Giotto" from the European Space Agency, was designed to study Halley's Comet. On March, 13, 1986, Giotto approached at a 596 kilometer distance from Halley's nucleus and obtained our first direct images of a comet nucleus. Giotto's images showed the nucleus to be an irregular object, something like a potato, with dimensions 15 km long and up to 10 km wide (picture).

A pale blue dot
It was Carl Sagan's idea to turn Voyager's camera back toward the planet that launched the spacecraft in order to reveal to that planet's inhabitants their "true circumstance and condition". After much resistance, Dr. Sagan prevailed, and on February 14, 1990, from a distance of 6.4 billion kilometers , Voyager 1 captured this image of our Earth. Here the entire world fills only 0.12 pixel and appears as a tiny crescent of light.

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate or your joy and suffering, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and distroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar", every "supreme leader", every saint and sinner, in the history of our species lived here -on a mote of dust suspended in a sunbeam.
The earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of a corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturing, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits that this distant image or our tiny world. To me, it underscores our responsability to deal more kindly with one another , and to preserve and cherish the pale blue dot , the only home we've ever known.

The colour in this image is due to it being a multitemporal composite, made up of three Advanced Synthetic Aperture Radar (ASAR) images acquired on different dates, with separate colours assigned to each acquisition to highlight differences between them: Red for 16 March, Green for 12 Jan and blue for 14 October 2004. The view was acquired in ASAR Image Mode Precision, with pixel sampling of 12.5 metres.
Satellite portrait of global plant growth will aid climate research
An ambitious ESA (European Space Agency) project to chart ten years in the life of the Earth's vegetation has reached a midway point, with participants and end-users having met to review progress so far. Harnessing many terabytes of satellite data, the GLOBCARBON project is intended to hone the accuracy of climate change forecasting. GLOBCARBON involves the development of a service to generate fully calibrated estimates of land products based on a variety of Earth Observation data, suitable for assimilation into sophisticated software simulations of the planet created by the global carbon modelling community.
The service is focused on the generation of various global estimates of aspects of terrestrial vegetation: the number, location and area of fire-affected land, known as Burnt Area Estimates (BAE), the area of green leaf exposed to incoming sunlight for photosynthesis, known as Leaf Area Index (LAI), the sunlight actually absorbed for photosynthesis, known as the Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) and the Vegetation Growth Cycle (VGC).
