What scientific observation did Edwin Hubble use to determine distances between galaxies?
As the light source passes Earth, the wavelength increases as the frequency increases.
As the light source moves toward Earth, the wavelength decreases as the frequency increases.
As the light source moves away from Earth, the wavelength increases as the frequency decreases.
As the light source affects the gravity of Earth, the wavelength decreases as the frequency decreases.

the vacuum of space.
intense sunlight
micrometeoroids.
water loss.
The Hubble Space Telescope is a telescope that NASA launched into space in 1990. Scientists MOST likely prefer to use the Hubble Space Telescope instead of a land-based
telescope because it provides better accuracy at
predicting solar eclipses.
investigating faraway galaxies.

Radio astronomers Arno Penzias and Robert Wilson discovered a microwave signal during their research in 1964. The microwaves were uniform and coming from all directions in the sky. The phenomenon known as Cosmic Microwave Background (CMB) provided evidence that the universe was once very hot and dense.
How did CMB contribute to the big bang theory?
CMB confirmed how matter expanded during the big bang.
CMB was the magnetic field that was created during the big bang.
CMB was a reflection of the thermal energy generated during the big bang.
CMB represented energy trails from moving matter that began with the big bang.
Telescopes use lenses to observe distant objects such as stars. Which term BEST describes what happens when lenses bend and concentrate light?
reflecting
polarizing
diffracting
refracting
Which of these is an unpiloted spacecraft designed to gather information while orbiting planets other than Earth?
space probe
space shuttle
space station
space telescope
Which of the following is visible through a reflecting telescope?

When human spaceflight began, NASA used the gravity assist concept so that spacecraft could conserve fuel. Which statement explains why the gravity assist concept was useful for spacecraft to successfully travel and return to Earth?
It gave spacecraft a timed trajectory.
It ensured spacecraft would return home safely.
It was helpful in planning spacecraft trajectories.
It ensured spacecraft would avoid being pulled into the Sun.
