... Canyon complex, Viking Orbiter photos have picked out wind-blown patches of dark material. These patches are strung out along faults for some 200 kilometers. Astronomers believe they are volcanic vents, which are a scant few million years old. (Anonymous; "Recent Volcanism on Mars?" Sky and Telescope, 73:602, 1985.) Comment. Another of the surprisingly large number of youthful features in the solar system. From Europa. The surface of Europa, one of Jupiter's large Galilean satellites, seems to be covered with a relatively smooth veneer of ice. Beneath this frigid skin, according to one theory, lie about 100 kilometers of liquid water. Why hasn't this water frozen completely, given the trifling sunlight at Jupiter's distance from the sun ... From Saturn. Micrometeorites constantly chip away at Saturn's C-ring. Using current micrometeorite-flux estimates, the age of the C-ring is between 4.4 and 67 million years. Compared to the purported age of the solar system, 4.5 billion years, Saturn's C-ring (and perhaps the other rings, too) is a brand-new feature. Where did it come from? Is it related to the icy comets that seem to be raining down steadily on the earth's atmosphere? (Northrop, T.G ., and Connerey, J.E .P .; "A Micrometeorite Erosion Model and the Age of Saturn's Rings," Icarus, 70:124, 1987.) From Mars. Inside ...

... separate arcs of material orbiting Neptune are "trying to decide whether to become a satellite." (Hecht, Jeff, and Henbest, Nigel; "Neptune's Arcs -- A Satellite in Formation?" New Scientist, p. 19, Apil 25, 1985.) Comment. If the debris around Neptune is just now accreting into satellites and Saturn's rings really do have youthful features (SF#39), one has to consider some disquieting possibilities: (1 ) Saturn and Neptune have been recently "disturbed," or (2 ) The entire solar system is not as old as the conventional scenario demands.

... Comments. Admittedly, this is a pretty shaky calculation, but it accords with the calculation that Halley had a close encounter with Jupiter about 20,000 years ago. The manifest contradictions in the inferences made above from recent observations of Halley mean that we still have a lot to learn about comets, Halley in particular. One should also recall that the solar system has other features that may be youthful, such as Saturn's rings. (See ARL16 in our catalog: The Moon and the Planets) For other cometary anomalies, see Chapter AC in our catalog volume: The Sun and Solar System Debris. Both catalog volumes are described here .

... from the rings. The satellites should be spiraling outward into ever larger orbits as they gain angular momentum, and the A-ring should collapse inward into the B-ring in just 100 million years as its particles lose angular momentum." (Kerr, Richard A.; "Making Better Planetary Rings," Science, 229:1376, 1985.) Reference. For other indications of youth in Saturn's rings, see ARL16 in our catalog: The Moon and the Planets.
