    • Distance light travels in a second

    • Distance to get to a planet

    • Distance light travels in a year

    • Distance light travels a round earth

    Correct Answer
    A. Distance light travels in a year
    Explanation
    A light year is the distance that light travels in one year. It is a unit of measurement used to describe vast distances in space. Since light travels at a speed of about 186,282 miles per second (299,792 kilometers per second), it can cover an immense distance in a year. Therefore, the correct answer is "distance light travels in a year."

    What does the Doppler Effect tell us about things in space?

    • Universe is expanding

    • Universe is going to pop

    • Universe is contracting

    • Universe is getting closer together

    • How close all the planets are getting

    Correct Answer
    A. Universe is expanding
    Explanation
    The Doppler Effect is a phenomenon that occurs when there is a change in frequency or wavelength of a wave due to the relative motion between the source of the wave and the observer. In the context of space, the Doppler Effect tells us that the light emitted by galaxies is shifted towards longer wavelengths, known as redshift, indicating that they are moving away from us. This observation supports the theory that the universe is expanding, as galaxies are moving farther apart from each other over time.

    What force is responsible for the formation of a star?

    • Surface temperatures, absolute magnitude

    • Gravity, friction

    • Radio, microwave, infrared, ultraviolet, visible

    • Protostar

    • Hydrogen, oxygen

    Correct Answer
    A. Gravity, friction
    Explanation
    Gravity and friction are the forces responsible for the formation of a star. Gravity causes the collapse of a cloud of gas and dust, pulling the material together. As the cloud collapses, friction between the particles generates heat, which eventually leads to the ignition of nuclear fusion and the birth of a star.

    Helium is fused to what in the core of red giants?

    • Hydrogen

    • Oxygen

    • Gravity

    • Main sequence

    Correct Answer
    A. Hydrogen
    Explanation
    In the core of red giants, helium is fused to hydrogen. This fusion process, known as hydrogen burning, occurs under high temperatures and pressures. It is the main source of energy for red giants, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. This fusion reaction sustains the red giant's luminosity and helps to counteract the force of gravity pulling the star inward.

    What do red shifts in our universe indicate?

    • Obects move towards eachother

    • Obects move away from eachother

    • Colder planets

    • Warmer planets

    Correct Answer
    A. Obects move away from eachother
    Explanation
    Red shifts in our universe indicate that objects are moving away from each other. This phenomenon is a result of the Doppler effect, where the wavelength of light emitted by an object is stretched as it moves away, causing a shift towards the red end of the spectrum. This observation supports the concept of an expanding universe and is a key piece of evidence for the Big Bang theory.

    The next stage in our sun's life is:

    • Main sequence

    • Protostar

    • Nebula

    • Red Giant

    • Super giant

    Correct Answer
    A. Red Giant
    Explanation
    As a star ages, it goes through different stages in its life cycle. The next stage after the main sequence, where our sun currently is, is the Red Giant stage. During this phase, the star expands and becomes larger in size, while its core starts to contract and heat up. The outer layers of the star become cooler and redder, hence the name "Red Giant." Eventually, the star will exhaust its nuclear fuel and undergo further changes, leading to the formation of a supergiant or other stellar remnants.

    What is Chromatic aberration?

    • Chemical energy providing colors

    • Different colors is focused at different places

    • Light rays bendining, or retracting

    Correct Answer
    A. Different colors is focused at different places
    Explanation
    Chromatic aberration refers to the optical phenomenon where different colors of light are focused at different places. This occurs due to the fact that different wavelengths of light refract differently when passing through a lens or other optical system. As a result, the image formed may have color fringes or blurring, especially towards the edges. This can be observed in photography or when using certain optical instruments.

    Which star colors have the highest surface temp?

    • Red

    • Green

    • Blue

    • Orange

    • Yellow

    Correct Answer
    A. Blue
    Explanation
    Blue stars have the highest surface temperature compared to other star colors. The color of a star is determined by its surface temperature, with blue stars being the hottest. The surface temperature of a star affects its luminosity and spectral type. Blue stars have a high energy output and emit a greater amount of ultraviolet radiation. This high temperature is a result of the intense nuclear reactions occurring within the star, causing it to emit a blue color.

    What does a prism do?

    • Gamma rays

    • Spectral line

    • Creates absorption spectrum

    • Creates continuous spectrum

    Correct Answer
    A. Creates continuous spectrum
    Explanation
    A prism creates a continuous spectrum. When white light passes through a prism, it gets separated into its component colors due to the phenomenon of refraction. This separation of light results in the creation of a continuous spectrum, where all the colors of the rainbow are visible. This is because different colors of light have different wavelengths, and as they pass through the prism, they bend at different angles. This bending causes the colors to spread out and form a continuous spectrum.

    What makes up 90% of the HR diagram?

    • Gravity

    • Protostar

    • Main sequence

    • Planets

    • Space

    Correct Answer
    A. Main sequence
    Explanation
    The main sequence makes up 90% of the HR diagram. The HR diagram is a graphical representation of stars, with temperature on the x-axis and luminosity on the y-axis. The main sequence is a diagonal band on the HR diagram that represents stars in the stable phase of their lives, where they are fusing hydrogen into helium in their cores. This phase is the longest and most common in a star's life cycle, which is why it makes up the majority of the HR diagram.

    What is a reflecting telescope and how is it different from a refracting one?

    • Reflecting telescope bounces off of things, while refracting bends light

    • Reflecting telescope goes througb space and back

    • Reflecting Telescopes bend and refracts light, while refracting uses a mirror

    • Reflecting telescope uses a mirror, while refracting bends light

    Correct Answer
    A. Reflecting telescope uses a mirror, while refracting bends light
    Explanation
    A reflecting telescope uses a mirror to gather and focus light, while a refracting telescope uses a lens to bend light. This is the main difference between the two types of telescopes. The mirror in a reflecting telescope reflects and focuses the light onto a secondary mirror, which then directs it to the eyepiece or camera. On the other hand, in a refracting telescope, the lens bends the light as it enters the telescope, focusing it onto the eyepiece or camera.

    What is a nebula?

    • A cold, dark, and dense cloud

    • A hole that sucks up everything near it.

    • A small planet that gives off red shifts

    • A warm bright cloud

    • Outerspace

    Correct Answer
    A. A cold, dark, and dense cloud
    Explanation
    A nebula is a cold, dark, and dense cloud in outer space. Nebulas are made up of gas, dust, and other particles. They can be the birthplace of stars and planets, as the particles within them come together under gravity to form new celestial bodies. Nebulas can also be illuminated by nearby stars, causing them to appear as warm and bright clouds. However, their true nature is a cold and dense cloud, where new formations are taking place.

    What happens to wavelengths in Doppler effect?

    • It get warmer when its really close and colder when its farther away

    • It gets colder when its really close and colder when its farther away

    • Objects move towards or away from an object

    • Objects move towards other objects

    • Obects move away from other objects

    Correct Answer
    A. Objects move towards or away from an object
    Explanation
    The Doppler effect is a phenomenon where the observed frequency of a wave changes depending on the relative motion between the source of the wave and the observer. When an object is moving towards the observer, the observed wavelength of the wave decreases, resulting in a higher frequency and a higher pitch. On the other hand, when an object is moving away from the observer, the observed wavelength increases, resulting in a lower frequency and a lower pitch. Therefore, the correct answer is "Objects move towards or away from an object."

    What is the difference between absolute and apparent magnitude?

    • Absolute magnitude shows how far away a planet actually is, and apparent magnitude shows how far a planet might be from earth

    • Absolute magnitude shows how bright a star is, and apparent magnitude shows how bright it actually is

    • Absolute, shows how bright a star actually is, and apparent magnitude shows how bright a star might be

    • Absolute magnitude shows how far away a star actually is, and apparent magnitude shows how far away a star is

    • Absolute magnitude shows how bright a planet actually is, and apparent magnitude shows how bright a planet is

    Correct Answer
    A. Absolute, shows how bright a star actually is, and apparent magnitude shows how bright a star might be
    Explanation
    The correct answer is "absolute magnitude shows how bright a star actually is, and apparent magnitude shows how bright it actually is." Absolute magnitude measures the intrinsic brightness of a star, independent of its distance from Earth. On the other hand, apparent magnitude measures the brightness of a star as observed from Earth, taking into account its distance. Therefore, absolute magnitude provides information about the true brightness of a star, while apparent magnitude reflects how bright it appears to us on Earth.

    What will be the final stage in our sun"s life cycle?

    • Main sequence

    • White dwarf

    • Red Giant

    • Super Red giant

    • Black dwarf

    Correct Answer
    A. Black dwarf
    Explanation
    The correct answer is Black dwarf. A black dwarf is the final stage in the life cycle of a sun-like star. After going through the stages of main sequence, red giant, and white dwarf, a star will eventually cool down and fade away, becoming a black dwarf. At this stage, the star will no longer emit light or heat, making it virtually invisible in the universe. However, it is important to note that black dwarfs have not yet been observed because the universe is not old enough for any white dwarfs to have cooled down completely to become black dwarfs.

    What is a black hole?

    • Sucks up everything that gets near it

    • Motional gravity pull

    • A spinning tornado in space

    • A worm hole

    • Time warp

    Correct Answer
    A. Motional gravity pull
    Explanation
    A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape its grasp. This intense gravitational force is often referred to as a "motional gravity pull" because it pulls everything that comes near it into its center. The term "motional" implies movement or motion, indicating that objects are drawn towards the black hole due to its gravitational influence.

    What do the Doppler Effect tell us about things in space?

    • Moves faster

    • Its expanding

    • Moves slowly

    • Its contracting

    • The planets shrink

    Correct Answer
    A. Moves faster
    Explanation
    The Doppler Effect tells us that things in space move faster. This effect occurs when there is a change in frequency or wavelength of a wave due to the relative motion between the source of the wave and the observer. In the context of space, the Doppler Effect is observed in the light emitted by celestial objects. If an object is moving towards us, the light waves get compressed, resulting in a higher frequency and a blue shift. On the other hand, if an object is moving away from us, the light waves get stretched, resulting in a lower frequency and a red shift. Therefore, the Doppler Effect tells us that objects in space can move faster.
