Very interesting news comes to us from scientists from NASA, who for many years supervised the mission of this probe, which studied Saturn and its moons. Well, with the help of the CDA space analyzer (Cosmic Dust Analyzer), i.e. one of the measuring devices installed on board the probe, grains of cosmic dust that did not come from our solar system were detected.
The dust was detected near Saturn, where the NASA device was still in operation 3 years ago. There is a lot of dust around the planet that makes up the famous rings. Most of it is ice, and it comes from active geysers on the surface of the mysterious Enceladus, one of Saturn's moons.
However, the grains analyzed by the probe contained elements such as calcium, silicon and iron, something completely different from the ones found on the moons of the Lord of the Rings. Scientists have revealed that they traveled at 72,000 kilometers per hour during observations, and that along a different path than the ice dust. Such a high speed guarantees the free flow of the grains throughout the entire solar system.
Scientists do not know exactly where it may come from, but it is certain that it is outside our solar system, i.e. interstellar space. They were probably thrown into space after a star exploded. Interestingly, NASA found similar material in the 90s of the last century, but then no detailed research was carried out, which made it impossible to clearly state what we were dealing with.
