The heliosphere is a giant “bubble” in outer space that surrounds the solar system and interstellar space. This giant “bubble” releases particles at all times, which in turn means that the solar system is protected from dangerous radiation.
So far, only two ships have managed to penetrate the “shield” of the solar system. Precisely for this reason, the area remains relatively under-explored, according to the Danish newspaper Extra Magazine.
Data from three different NASA spacecraft is now giving a closer look at what the outer edges of the Solar System will look like, and many scientists were surprised by the details they saw.
It took several decades
Several researchers looked at data from the IBEX probe, which was launched in 2009. Its goal was to map the heliosphere. come out in one New study About it was published in the scientific journal Nature Astronomy.
The only objects that have come close to space exploration outside our solar system are the Voyager probes.
Voyager 1 and 2 were launched in the 1970s, and it took several decades before they actually reached the edge of the heliosphere.
35 years after leaving Earth, the probe has broken the barrier between the heliosphere and interstellar space, the heliosphere.
Now the researchers have analyzed the measurements from the sensors, and discovered a sudden change in solar wind pressure.
This discovery made it possible to study the borders more closely, as well as to obtain a more detailed picture of their actual shape.
Several ripples or giant waves were also detected in the heliosphere itself.
The waves were the size of ten astronomical units, where one unit corresponds to the distance between the Earth and the Sun.
I will renew the equipment
The researchers also noticed significant differences in the distance to the border region itself.
This indicates that the heliosphere is constantly changing, and the shape of the protective “bubble” is not uniform.
Many astronomers now hope to learn more about the outer edge of the solar system.
NASA plans to replace the IBEX probe with IMAP in 2025. In addition, they will replace the equipment, so that it will be easier to map the area.
