Best comet of 2021 passing Earth this week on its way to Sun

The video discusses the heliosphere, a protective bubble around our solar system, traditionally viewed as comet-shaped. New models suggest it resembles a croissant due to interactions between solar and interstellar magnetic fields. This shape results from Rayleigh Taylor instability caused by neutral hydrogen atoms. Data from Voyager probes, which are in interstellar space, support these findings.
