NGSS.HS-ESS1-4

All objects viewed from Earth have slightly longer wavelengths. Evidence suggest that all objects in the universe are

• moving away from each other.

• hotter than our Sun.

• older than our solar system.

• absorbing radiation from stars.

Which of the following characteristics of elements are used by astronomers to determine what distant stars are made of? All Elements -

• are composed of smaller particles, such as protons.

• can be found on the periodic table of elements.

• emit certain wavelengths of light when heated.

• are able to combine with others to form compounds.

The absolute color of light emitted by a star is most useful in telling us--

• the age of the star.

• orbit.

• distance

• temperature

What is the advantage to using radio waves to view stars.

• Radio waves travel faster than light waves

• Radio waves allow us to observe stars during the day

• Light waves cannot give information about temperature

• X-rays can see supernovas

NGSS.HS-PS4-5

X-ray telescopes are used to measure the temperature of extremely hot radioactive stars such as -

• Clouds of water vapor in the atmosphere

• gases released by a supernova

• dust and gas in a nebula

• planets orbiting a main sequence star.

The electromagnetic spectrum uses different _________________ to distinguish from the different forms of radiation.

• amplitude of wave

• speed

• wavelength

• intensity

NGSS.HS-PS4-1

Scientists make observations in different wavelengths because

• information provided by visible light is not a reliable source

• observations in different wavelengths provide different information about the stars.

• the equipment required for observations in other wavelengths is expensive

• temperature

• direction it is moving

• chemical composition

• number of planets orbiting the star.
