What makes up the universe?

• The universe is made up of disconnected stars and planets.

• The universe is made up of scattered planetary matter around stars.

• The universe is made up of hundreds of galaxies that contain millions of stars.

What information is needed to calculate the absolute magnitude of a star?

• color and temperature of the star

• color and composition of the star

• apparent magnitude and distance from Earth of the star

• color and distance from Earth of the star

Why do scientists study images made with parts of the electromagnetic spectrum other than visible light?

• These images are the only way to observe galaxies beyond our own.

• These images reveal information that visible light does not show.

• These images show important data from optical telescopes.

• These images are the only way to observe space from Earth’s surface.

Gabriella observes that the color of a star is similar to the color of the sun. Therefore, she infers that the star and the sun have similar sizes and surface temperatures. What can she conclude about the star?

• The star is a white dwarf.

• The star is medium sized.

• The star is hotter than most other stars in our galaxy.

• The star is brighter than most other stars in our galaxy

In convection, hot gases rise through cooler gases as they travel to the top of the convective zone. Once they reach the top of the convective zone, they cool. What happens to these gases next?

• They create sunspots.

• They sink back down.

• They give off energy in solar flares.

• They begin the process of nuclear fusion.

Neveah makes a model of the Sun. She uses pulled-apart cotton balls for the outer layer, foam for the middle layer, and a small, solid rubber ball for the core. Why did Nevaeh used the small, solid rubber ball as the core of the Sun?

• The ball is light and airy like the core.

• The ball is solid and bouncy like the core.

• The ball is dark and hollow like the core.

• The ball is small and dense like the core.

Which telescope would be used to detect temperature signatures?

• radio telescope

• infrared telescope

• reflecting telescope

• refracting telescope

How is energy transferred from the core of the Sun to its outer layers?

• Energy radiates outward from the core as visible light.

• Energy is carried inward from the outer layers by convection.

• Energy is radiated out from the core first, then carried to the outer layers by convection.

• Energy is carried out from the core by convection first, then radiated to the outer layers.

Why does light from the Sun travel so quickly to Earth?

• Light waves travel fastest through solids.

• Light waves travel fastest through gases.

• Light waves travel fastest through liquids.

• Light waves travel fastest through a vacuum.
