synonymheliosheath (The area between the heliosphere top and the terminal shock wave is the outer boundary of the solar system, which is distributed on the edge of the bubbles created by the solar wind.) It generally refers to the area of solar sheath consumption
Scientists previously believed that when leaving the solar system, its magnetic field will suddenly disappear completely, that is, the solar system has a clear boundary, but the information sent back to the Earth by Voyager 1 shows that the solar system has no clear boundary, and its magnetic field will gradually weaken when approaching the edge.Research shows that the number of solar charged particles in the region where Voyager 1 is located has dropped sharply, and the cosmic rays from outside the solar system have increased sharply.But the detector can still feel the magnetic field from the sun, although it has begun to weaken.
Therefore, researchers call this newly discovered unknown area "solar sheath consumption area", which is the outer boundary of the solar system.
The solar sheath consumption area is the solar sheath consumption area launched by NASA in 1977Space probe“Voyager 1”The name of an unknown region reaching the edge of the solar system

On June 27, 2013, the website of Science magazine of the United States reported that the space probe "Voyager 1" launched by NASA in 1977 sent back "amazing" information at the edge of the solar system - humans may have found the "gate" of the solar system to interstellar space.According to the report written by NASA and other institutional scientists, Voyager 1 is about 18 billion kilometers away from the sun, 125 times the distance from the earth to the sun.Judging from the data it sent back, this probe, which has been flying in the solar system for 36 years, did not completely fly out of the solar system as previously predicted.Instead, it has reached a new unknown area.
Researchers said that the solar system has no clear boundary, and the discovery of this area, known as the "magnetic highway", was unexpected.It is speculated that this may be the outermost frontier of the solar system and the "gate" to interstellar space.

From this, researchers believe that the solar system may not have a clear boundary, but rather a fuzzy transition region, which is not completely part of the solar system, nor is it a complete interstellar space, but an interface between the two.
Therefore, researchers call this unknown "new continent" as "solar sheath consumption area", which is the outer boundary of the solar system.

How long will Voyager 1 fly before it leaves the solar system?
"I think it may be several years, maybe 2015," said Edward Stone, a scientist of NASA's Traveler program.He said that the phenomenon observed so far is "unprecedented", and there is no model to refer to. "All these are brand new, and so far we are lucky, because the detector has not had any catastrophic failure."
"Voyager 1 surprised us," Stone said
Researchers hope that Voyager 1 will fly out of the solar system before 2020, when its scientific instruments will have to be shut down gradually.By 2025, the nuclear power generator carried by Voyager 1 will be dead.At that time, it will completely become a lonely envoy of the earth, with human greetings, and continue to fly to the depths of space.

"Voyager 1" carried a copper disk record containing greetings in 55 human languages and various kinds of music.The 55 languages include four Chinese languages (Cantonese, Mandarin, Minnan, Wu), as well as some obscure languages such as ancient Mesopotamian Akkadian. The greeting content is: "The children of the planet Earth say hello to you".
In addition to the above greetings, the album includes greetings from then UN Secretary General Waldheim and then US President Carter.
There is also a 90 minute vocal music collection on the record, including various sounds of nature and 27 world famous songs, including Chinese guqin song "Running Water", Mozart's "Magic Flute", etc.In addition, there are 115 images, pictures of planets in the solar system, human images and descriptions on the album.[1]
