The video explores the edge of the solar system, focusing on the heliosphere and heliopause as boundaries. It highlights the contributions of NASA's IBEX and Voyager 1 in mapping these regions. Key discoveries include the dynamic nature of interstellar space, the solar system's oxygen richness, and the absence of a bow shock. These findings enhance our understanding of the solar system's interaction with interstellar space.

What is the heliosphere?

• A region dominated by the sun's gravity

• The farthest point light from the sun can reach

• A region dominated by the sun's solar wind

• The orbit of the farthest object in the solar system

How does IBEX detect the heliopause?

• By measuring the sun's light intensity

• By observing the farthest orbiting object

• By detecting energetic neutral atoms (ENAs)

• By tracking the sun's gravitational pull

What surprising feature did IBEX discover in the heliopause?

• A ribbon-like region with more ENAs

• A consistent production of ENAs

• A complete absence of ENAs

• A static and unchanging environment

What did IBEX reveal about the solar system's oxygen levels?

• The solar system has average oxygen levels

• The solar system is oxygen-rich compared to its surroundings

• Oxygen levels are irrelevant to the study

• The solar system is oxygen-poor compared to its surroundings

What did IBEX not find that was previously expected?

• A new star

• A black hole

• A new planet

• A bow shock
