starspirit discovered 14 months ago- Staring across interstellar space, the alluring Cat's Eye nebula lies three thousand light-years from Earth. A classic planetary nebula, the Cat's Eye (NGC 6543) represents a final, brief yet glorious phase in the life of a sun-like star. This nebula's dying central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layers in a series of regular convulsions. But the formation of the beautiful, more complex inner structures is not well understood. Seen so clearly in this sharp Hubble Space Telescope image, the truly cosmic eye is over half a light-year across. Of course, gazing into the Cat's Eye, astronomers may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution ... in about 5 billion years.

Are contemporary visual artists giving better visual signs of the knowledge of our times than macro or micro visualizations; as for example this one? I don't think so. Most of present-day visual signs given by artists are exclusively concerned with form their substance being a-knowledge. Remember Duchamp's word: "... being dumb as a painter". Well it accurately describes the contemporary visual art scene. Kandinsky gave us one of the best one sentence definitions about form and substance: "The artist must have something to say, for mastery over form is not his goal but rather the adapting of form to his inner meaning". I don't think that visualizations of the micro, macro or abstract realm can be described as art. They are reflections of the state of present-day "knowings" about reality. Artists and wisemen should integrate those knowings into a whole system of knowledge of our times and their visual signs should be reflections of that whole system of knowledge. In my mind this is the only way to close the circle of search, started around 1900, for the representation of something else than the first dimension of what our eyes can see ... and re-join with the historical functionality of art that traverses all epochs of human biological and societal evolution. Hum... See Scientific visualization. Is it art?
