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.

What is the primary function of the heliosphere?

• To produce light and heat

• To create magnetic fields

• To generate solar winds

• To protect the solar system from cosmic radiation

How does the new model describe the shape of the heliosphere?

• Like a perfect sphere

• Like a flat disc

• Like a comet's tail

• Like a giant croissant

What traditional shape was previously attributed to the heliosphere?

• A spiral galaxy

• A spherical bubble

• A flat disc

• A comet's tail

What causes the Rayleigh Taylor instability in the heliosphere?

• Interaction of solar winds with Earth's atmosphere

• Magnetic fields colliding with cosmic rays

• Neutral hydrogen atoms interacting with ionized matter

• Solar flares impacting the heliosphere

Which space probes provided data for the new heliosphere model?

• Voyager probes

• Hubble Space Telescope

• International Space Station

• Mars Rovers
