The following image was taken by the Hubble telescope.
Which of the following options best describes what is being observed?
The image is a nebula that is thousands of light years wide, containing stars, galaxies, and planets.
The image is a galaxy, that is thousands of light years wide, containing solar systems, nebulae, planets and millions of stars.
The image is the Universe, that is thousands of astronomical units wide, inside a galaxy containing all the stars and planets.
The image is a solar system, hundreds astronomical units wide, that contains a star in the center with planets, moons, and asteroids orbiting it.
When studying celestial bodies, scientists examine satellite images of the same object made with different waves of the electromagnetic spectrum. How does using different types of electromagnetic waves provide a more complete understanding of the celestial bodies?
EM waves have the same energy which provides unique information.
EM waves travel at different speeds which provide unique information.
EM waves travel the same distance which provides unique information.
EM waves have different wavelengths which provide unique information.
Jackson, Kristy and James are placing cards on a chart that shows the approximate size of Earth,the Milky Way, the Moon, the Sun and an asteroid. Their teacher put the Earth card in the correct place.
Which point on the chart best represents the approximate size of an asteroid?
point 1
point 2
point 3
point 4
Satellites are used mainly to gather light from cosmic objects. The Hubble telescope's mirror captures light and directs it into its several science instruments.
How is this technology advancing our understanding of the universe?
It is capable of counting individual atoms in a substance in order for scientists to study them.
It is capable of sending audio communication to other planets in our solar system for them to respond.
It has already sent pictures that show other planetary systems in the universe in order for scientists to study them.
It is capable of sending clear, distinct images of distant objects, like other galaxies in order for scientists to study them.
Meteorologists use satellites to study global weather patterns and gain a better understanding of weather predictions.
What choice below should meteorologists used to see patterns of heat flow through the atmosphere?
Infrared waves, because the wavelength is lower than visible light.
Ultraviolet waves, because the wavelength is lower than visible light.
They will have to use gamma rays to determine the thermal energy in the atmosphere.
They will have to use different kinds of sensors because the electromagnetic spectrum produces similar types of radiation.
