A NASA probe finds signs of a huge structure at one end of the solar system

An ultraviolet glow incorporated with a New Horizons spectrometer can reveal the presence of a hydrogen wall in the Kuiper Belt.

NASA & # 39; s unmanned spacecraft New Horizons has recorded a source of ultraviolet radiation in a border region of the solar system. The constant background signal, recorded by a spectrometer, can come from a hydrogen wall in the Kuiper belt, located behind the dwarf planet Pluto.

According to this main version, which a group of astrophysicists develops in an article published last week in Geophysical Research Letters, the source would be located "near where the interstellar wind meets the solar wind". However, it could also be another object that is further away, something that a journalist from Science Alert said Wednesday about an enormous structure on the edge. of our planetary system and described this source of charisma as & # 39; mysterious & # 39 ;.

The author still considers the hydrogen wall as the "best explanation" and compiles the words of astronomer Leslie Young of the New Horizons operators team, who described the phenomenon as "the threshold between being in the solar environment and in our galaxy. "Experts also assume a kind of disturbance & # 39; for the neutral hydrogen atoms in the area concerned.

The New Horizons probe woke up early June after a period of hibernation to make the largest space flight from the story to the unidentified object & # 39; 2014 MU69 & # 39; in the Kuiper belt, known as Ultima Thule. It happened in 2015 near Pluto, the ninth planet of the solar system.
