A ring of dust was discovered around Jupiter that rotates it in the opposite direction to the movement of the planet around its axis. The researchers discovered the ring in computer simulation based on the findings of the "Galileo" spacecraft.
Pasadena (IP). Evidence of the existence of a ring of dust around the planet Jupiter, moving in the opposite direction to the movement of the star around its axis, was found by the "Galileo" spacecraft. The discovery, based on dust remnants collected by Galileo and computer imaging, was reported in the Friday issue of the magazine "Science".
The report relies on data from the Jet Laboratories of the American Space Agency (NASA), which oversee Galileo's activities. A thin, round ring of interstellar dust, with a diameter of about 1,112,000 km, orbits the star. Scientists led by a team of researchers from the University of Colorado believe so. It seems that most of the dust moves in a "retrograde" orbit - contrary to the direction of movement of the star and its moons. This is what Joshua Colwell of the Atmospheric and Space Physics Laboratory at the university said. According to him, the reason for the reverse course of the ring is not clear. Evidence of the ring's existence was obtained through computer imaging that processed the information transmitted by the Galileo spacecraft, which was launched in 1989 and has been studying the planet Jupiter and its moons since 1995.
"A second ring on Jupiter" In 1979, the Voyager 2 spacecraft detected an uneven ring of dust around Jupiter. The prevailing hypothesis is that the ring was formed by collisions between small moons and asteroids in the planet's vicinity. Looks bigger and thinner. Colwell said he thinks a similar ring may also be found around a star Saturn's orbit, which NASA's "Cassini" spacecraft is expected to reach in 2004. Cassini is scheduled to pass by the planet Venus on April 26.
