A group of American scientists have confirmed that there is a bubble-like structure that is enveloping the Sun and all of its planets, including the Earth of course.
This bubble is not metaphorical at all, but a real, literal bubble, as confirmed by professor of astronomy Merav Opher from the Boston College of Arts and Sciences and the Center for Astrophysics (under the University of California). Boston University), who led the study.
Professor Opher and his colleagues used a special computer model, combined with data from NASA’s Voyager 1 spacecraft, a spacecraft that has wandered all the way to the edge of the solar system.

According to astrophysicist James Drake from the University of Maryland (USA), a member of the research team, this bubble structure created by the Sun, by powerful jet rays, protects the planets by blocking the planets. fierce cosmic rays in the galaxy entering the heliosphere.
Their model shows that neutral hydrogen particles emitted in the outer solar system play an important role in the formation of this heliosphere bubble. The Sun’s jet rays collide with cosmic rays in the galaxy, creating a wall-like structure, invisible and stable, causing the cosmic rays to bend to avoid the heliosphere, according to Phys.org .
The shape of this bubble is still controversial, although many other research groups are also trying to prove its existence. Professor Opher’s team provided an image of a distorted bubble, while other models from other research groups suggest it could be more elongated or have a comet-like tail.
The study has just been published in the Astrophysical Journal.
