Voyager 1 has already left the solar system?

Question

Space

Judging by the number of external particles, it has already left. But I can't find any news about it.
voyager.jpl.nasa.gov
It is not clear if he left, then why nothing is written about this on the NASA website. Or has he left yet?

Answer 1

There is no official announcement, most likely because the solar system does not have a clear boundary - they themselves do not know whether it has come out or not.
That is why they put up a counter on the site, they say, see for yourself and decide for yourself.
In the meantime, there is a possibility that some recognized scientist will undertake to refute such a statement, NASA will not make it (the statement).

Answer 2

“Last December, an automatic probe reached the transition zone at the edge of the heliosphere, where the lines of force of the magnetic fields of the Sun and interstellar space connect. A change in the direction of the magnetic field lines is the last key indicator that interstellar space has been reached, but such a change has not yet been observed.

Answer 3

>What's this?
Scientists have three key indicators for determining whether the Voyager spacecraft have reached interstellar space.
1)"Inside Particles"
A drop to about 2 particles per second of low-energy particles means that particles originate from inside the solar bubble. (Scientists consider a drop to the background rate of about 2 particles per second to mean there are no more inside particles.)
2) "Outside Particles"
An increase and leveling off of high-energy particles coming in from far outside our solar system.
3) A shift in the direction of the magnetic field or measurements of the plasma environment.
The gauge shows the data sent back from the Voyager spacecraft in average particles per second. If the outside particles show a sudden increase and the inside particles a sudden decrease, and these levels hold steady, the spacecraft are closing in on the edge of interstellar space. Scientists will only then have to verify the third key sign - a change in the direction of the magnetic field - before announcing that Voyager has entered interstellar space.
