Question 4

What is the relationship between the terms magnetic reconnection and magnetic bubbles as they are used in the article?

Accepted Answer

Magnetic reconnection is what causes the magnetic bubbles to form.

Answer

Magnetic reconnection is what solar flares use to create magnetic bubbles.

Answer

Magnetic reconnection occurs when magnetic bubbles rejoin the sun.

Answer

Magnetic reconnection is what allows magnetic bubbles to create solar flares.

Question 5

Part A: Why does the author provide an explanation of the graceful-arc theory of the sun’s magnetic field?

Accepted Answer

to establish the idea that current data from Voyager probes seems to contradict previously held theories

Answer

to demonstrate the relationship between the Sun’s magnetic field and the rate at which Voyager can send information back to Earth

Answer

to introduce the beliefs about our solar system that the Voyager mission was designed to disprove

Answer

to show what the Voyager is attempting to find as it reaches the outer edge of the Sun’s magnetic field

Question 6

Part B: How does this explanation contribute to the author’s purpose in the article?

Accepted Answer

It provides support for the idea that scientific theories change as new information becomes available.

Answer

It gives an example that explains one of the Voyager’s primary goals.

Answer

It provides support for the claim that the Voyager is NASA’s primary tool for making discoveries in space.

Answer

It gives an example of one way that scientists can learn new things from oldm experiments.

Question 7

In the article, the author reveals Opher’s claim that “The magnetic bubbles appear to be our first line of defense against cosmic rays . . .” Which sentences from the article is most helpful to develop this claim?

Accepted Answer

“When these microscopic cannonballs try to enter the solar system, they have to fight through the sun’s magnetic field to reach the inner planets.”

Answer

“Lots of things try to get across—interstellar clouds, knots of galactic magnetism, cosmic rays, and so on.”

Answer

“The crowded folds of the skirt reorganize themselves, sometimes explosively, into foamy magnetic bubbles.”

Answer

“The actual bubbles appear to be self-contained and substantially disconnected from the broader solar magnetic field.”

Question 8

Which of these possible ideas could be used to introduce a summary of the article?

Accepted Answer

A new theory of magnetic foam is based on information gathered by the Voyager spacecraft.

Answer

The border between the Milky Way and the Solar System is known as “the heliosheath.”

Answer

Cosmic rays are subatomic particles that travel at nearlight speed.

Answer

Scientists expect to make further discoveries based on data recorded by the Voyager craft.

Question 9

Which of these possible ideas could be used to conclude a summary of the article?

Accepted Answer

Scientists expect to make further discoveries based on data recorded by the Voyager craft.

Answer

Scientists believe the foam-like magnetic fields are caused by the spinning of the sun.

Answer

Cosmic rays are subatomic particles that travel at nearlight speed.

Answer

The border between the Milky Way and the Solar System is known as “the heliosheath.”

Question 10

Which excerpt from the video best demonstrates the central idea?

Accepted Answer

“The smooth, streamlined look is gone, replaced with a bubbly, frothy outer layer.” (1:20-1:23)

Answer

“When they arrive at the bubble region, they slowly move from bubble to bubble until they can reach smooth magnetic field lines, and follow them toward the sun.” (1:31-1:38)

Answer

“The sun’s magnetic field spins on opposite directions on the North and South Poles, creating a sheet where the two spins meet.” (0:46-0:52)

Answer

“The two Voyager spacecraft have been travelling away from earth for more than thirty-three years, and they are finally in the outer edge of the solar system.” (0:14-0:20)

Question 11

Part A: Why does the author of the article compare cosmic rays to cannonballs?

Accepted Answer

to explain the technical topic of cosmic rays using a familiar object

Answer

to describe the shape and trajectory of cosmic rays

Answer

to clarify the role dangerous cosmic rays play in space

Answer

to illustrate the explosive nature of the process of forming cosmic rays

Question 12

Part B: Which excerpt from the video demonstrates a technique similar to the answer to Part A?

Accepted Answer

“When this sheet reaches the termination shock, it starts to compress, like water hitting a wall.” (0:59 – 1:04)

Answer

“This sheet gently ripples as it travels outward, and the ripples get bigger as they go.” (0:53 – 0:57)

Answer

“As the solar wind travels out from the sun, it pushes against the galactic medium and abruptly slows down.” (0:29 – 0:33)

Answer

“This new layer also changes our understanding of how extremely fast-moving particles, called cosmic rays, enter our solar system.” (1:24 – 1:31)

Question 13

In paragraph 9 of the article, the author claims that “Energetic particle sensor readings suggest that the Voyagers are occasionally dipping in and out of the foam—so there might be regions where the old ideas still hold.” Which image from the video best supports this claim?
