The Voyager 1 spacecraft, which has gone beyond the boundaries of the solar system, measures the plasma density in the open universe.
Astrophysicist from the University of Iowa, Don Garnett, who works with data coming from the spacecraft, is confident that the model of the distribution of plasma and stellar wind corresponds to the present state of affairs with fairly high accuracy.
Voyager 1, having crossed the heliosphere created by the solar wind, is recording signals coming from space, and also recorded the singing of plasma from distant stars. “We jumped on chairs when we heard these sounds – they show that the device entered a completely new area of space, the characteristics of which are still unknown to us,” Garnett said at a press conference dedicated to the event. He also shared that another mystery haunts scientists – the intensity of the magnetic field, measured by the probe constantly, does not fall, and does not change direction – an explanation for this phenomenon has not yet been found.
