NASA | IBEX | What are the Boundaries of our Solar System?

The video explains the IBEX mission's study of the solar system's boundaries, including the termination shock, heliopause, and bow shock. It uses animations and a kitchen sink analogy to illustrate how the solar wind interacts with interstellar space, forming a protective barrier against galactic cosmic rays, which shields Earth and astronauts from radiation.

What is the primary focus of the IBEX mission?

• Studying the planets in our solar system

• Exploring the sun's core

• Analyzing the Earth's atmosphere

• Investigating the boundary between the solar wind and interstellar space

What is the heliopause?

• The edge of the Earth's atmosphere

• The point where the solar wind stops completely

• The boundary separating solar and galactic materials

• The boundary where the solar wind originates

Why is the bow shock formed?

• Because the solar system is stationary

• Due to the solar system moving through galactic material

• Because of the Earth's gravitational pull

• Due to the sun's magnetic field

How can the solar wind's behavior be demonstrated at home?

• By shining a flashlight in a dark room

• By using a magnet to attract metal

• By bouncing a stream of water off a flat surface

• By using a fan to blow air

What role does the solar wind play in protecting Earth?

• It increases the Earth's temperature

• It deflects galactic cosmic rays

• It causes solar eclipses

• It creates the Earth's magnetic field
