The authors of the work developed four star trackers. These airborne cameras capture the sky every quarter
In the photographs, the authors saw dust particles that crashed into the Juno mission at a speed of about 16 thousand km per hour. They broke off submillimeter pieces of the spacecraft.
The authors of the work noted that most dust collisions were recorded between Earth and the asteroid belt, with discontinuities in the distribution associated with the influence of Jupiter's gravity.
Until now, scientists have not been able to measuredistribution of these dust particles in space. Dedicated dust detectors had limited collection areas and therefore limited sensitivity. They basically counted more abundant and much smaller dust particles from interstellar space.
As for the outer edge locatedabout two astronomical units (AU) from the Sun (1 AU-distance between the Earth and the Sun), then it ends just behind Mars. The only known object in an almost circular orbit is Mars, so only it can be the source of this dust.
Although there is now compelling evidenceAlthough Mars is the dustiest planet known to us and is also the source of zodiacal light, the authors still cannot explain exactly how dust could escape the clutches of Martian gravity. Work in this direction continues.
