Voyagers’ readings yield new clues about the solar system’s structure

The video discusses the boundary region where the sun's influence ends and interstellar space begins, known as the heliosphere. It highlights Voyager 2's findings of a sharp difference in magnetic particles and plasma density at the heliopause, suggesting it is thinner and less affected by solar cycles than previously thought. The sun creates the heliosphere by emitting solar wind, which interacts with interstellar winds, forming a distinct boundary.

What is the heliosphere?

• A solar cycle phenomenon

• A type of interstellar space

• A bubble around the solar system created by the sun

• A region where the sun's influence ends

What did Voyager 2 discover when it crossed the heliopause?

• A sharp difference in magnetic particles and plasma density

• An increase in solar cycle activity

• A decrease in solar wind speed

• A new type of interstellar particle

How does the heliopause compare to previous expectations?

• It is more influenced by interstellar winds

• It is unaffected by solar cycles

• It is thinner and less changeable

• It is thicker and more changeable

What primarily composes the solar wind that creates the heliosphere?

• Hydrogen

• Carbon

• Oxygen

• Helium

What causes the sharp boundary in the heliosphere's outer region?

• The beginning of interstellar space

• The end of the sun's magnetic field

• The presence of a new type of particle

• The clash of solar and interstellar winds
