![]() ![]() This caducity is the main subject of his photographic research, in which he combines analogical and digital techniques. His works, with their dynamic and material surfaces, express a feeling of man's transitory existence. His artistic research explores new creative approaches through 3D design and investigates the visual relationship between real objects and their representation. Graduated in Design with honors from the University of Florence, he participates in international competitions and his artworks are appreciated and purchased by collectors around the world. Painting has always been an essential element of his life: he has been painting since he was a kid, mixing a wide range of artistic techniques and experimenting with creativity. But as the first spacecraft to visit the Kuiper belt is only just about to reach Pluto after a nine-year journey, it may be a long time before the Sedna mystery is settled.Mattia Paoli (1991) is an artist from Florence, and has been active in the artistic field for a very long time. If we could show that Sedna-like objects have a different chemical make-up from the rest of the Kuiper belt, that would be convincing evidence that they were stolen from another star. “A big piece of the puzzle is still missing.” “It remains to be shown that the massive shepherd – or its building blocks – could have survived the fly-by,” he says. Such a planet doesn’t seem to sit comfortably within the passing-star scenario. Scott Kenyon of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, who together with Ben Bromley of the University of Utah in Salt Lake City was one of the first to propose the idea, says the simulations are “pretty convincing”.īut Bromley points out that the orbits of Sedna-like objects show a persistent alignment that is hard to explain without the “shepherding” effect of a larger planet lurking in the outer solar system. ![]() The passing star would itself have stolen hundreds of ice dwarfs from the sun’s Kuiper belt, and flung hundreds more into interstellar space. ![]() The encounter probably took place when the sun was very young and still a member of a newly born star cluster. They conclude that the passing star would have been 80 per cent more massive than the sun, and that it came as close as 34 billion kilometres – 51 times Neptune’s distance. Using a low-cost, custom-built supercomputer, the team simulated over 10,000 possible encounters to find out which combination of a star’s mass, fly-by distance and velocity would lead to ice dwarfs being gravitationally captured into Sedna-like orbits. ![]()
