Meteors Ascendances is a series of cyanotypes representatives astral theme of meteorite impacts. These themes are said sidereal because they have the particularity to be a mix between astrological constellations and terminology used in astronomy. Photographic process from the early twentieth century obtained by exposing a photosensitive mixture to UV, the cyanotype is used here to draw a map of the sky at the moment of impact. Running an asteroid and solar ultraviolet radiation follow the same path to the earth to shine in these graphics. Positioning of the constellations and planets is so schematically, offering an analysis between scientific review and metaphysical perception.
