There are two major components to this story that, at first glance, don't seem to have a lot to do with each other.
The first is that Earth's spin is slowing down. The reason Earth's spin is slowing down is because the Moon exerts a gravitational pull on the planet, EARTH. which causes a rotational deceleration since the Moon is gradually pulling away.
In 1977, NASA launched the Voyager probes to study Solar System's edge & the interstellar medium between the stars. 1 by 1, both hit "wall of


Here There are a few ways one can define edge of the Solar System – for instance, where the planets end, or at the Oort cloud, the boundary of the Sun's gravitational influence where objects may still return closer to the Sun. One way is to define it as the edge of the Sun's magnetic field, where it pushes up against the interstellar medium, known as the heliopause.
"The Sun sends out a constant flow of charged particles called the solar wind, which ultimately travels past all the planets to some three times the distance to Pluto before being impeded by the interstellar medium," NASA explains. "This forms a giant bubble around the Sun and its planets, known as the heliosphere."
It is beyond that where the heliopause lies. "The boundary between solar wind and interstellar wind is the heliopause, where the pressure of the two winds are in balance. This balance in pressure causes the solar wind to turn back and flow down the tail of the heliosphere," NASA continues. "As the heliosphere plows through interstellar space, a bow shock forms, similar to what forms as a ship plowing through the ocean." Photo below courtesy from Tee tiong huat.

As NASA's Voyager Spacecraft Found A 30,000-50,000 Kelvin "Wall" At The Edge Of Our Solar System. Temperatures there reach an astonishing 30,000-50,000 kelvin. Voyager in space (artist concept).As NASA explains. "This forms a giant bubble around the Sun and its planets, known as the heliosphere." It is beyond that where the heliopause lies.
"The boundary between solar wind and interstellar wind is the heliopause, where the pressure of the two winds are in balance. This balance in pressure causes the solar wind to turn back and flow down the tail of the heliosphere," NASA continues. As the Voyager spacecraft continue to send us data from beyond this "wall", the only two probes that have crossed it so far, nearly 50 years after they were launched. Together they have found several surprises on our first glimpse outside the Solar System.
