Galaxies

What are some key components of optical telescopes?

• Sound, texture, and taste
• Speed, altitude, and temperature
• Weight, color, and size
• Magnifying power, brightness, and resolving power

How do reflecting and refracting telescopes differ?

• Reflecting telescopes use mirrors, while refracting telescopes use lenses
• Reflecting telescopes are smaller than refracting telescopes
• Refracting telescopes are only used in space
• Reflecting telescopes are more expensive

What is the primary purpose of detectors and image processing in telescopes?

• To measure the distance between stars
• To enhance the quality of captured images
• To analyze the chemical composition of planets
• To create artificial images of space

How are low mass stars involved in the H-R diagram?

• They emit radio waves constantly
• They are stationary in the universe
• They are invisible to telescopes
• They are born and die

What is the primary function of radio telescopes?

• To study the behavior of comets
• To detect radio waves from space
• To observe the color of planets
• To measure the temperature of stars

What is the significance of the Hubble Space Telescope in astronomy?

• It measures the temperature of planets
• It captures images of distant galaxies and stars
• It observes radio waves from space
• It studies black holes exclusively

Why are galaxy clusters important in astronomy?

• They are sources of dark matter
• They have no impact on star formation
• They emit visible light constantly
• They contain only black holes

How are neutron stars, pulsars, and black holes connected?

• They emit visible light constantly
• They are found only in our solar system
• They are stages in star evolution
• They are all types of galaxies

What role does dark matter play in the interactions of galaxies?

• It causes galaxies to collide
• It creates new stars in galaxies
• It has no impact on galaxies
• It influences the rotation of galaxies

What is the Chandrasekhar limit related to?

• Birth of stars
• White dwarfs
• Formation of galaxies
• Supernovae explosions
