### What is the difference between absolute and apparent magnitude?

• A.

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

• B.

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

• C.

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

• D.

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

• E.

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

C. 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.

### The next stage in our sun's life is:

• A.

Main sequence

• B.

Protostar

• C.

Nebula

• D.

Red Giant

• E.

Super giant

D. 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 force is responsible for the formation of a star?

• A.

Surface temperatures, absolute magnitude

• B.

Gravity, friction

• C.

Radio, microwave, infrared, ultraviolet, visible

• D.

Protostar

• E.

Hydrogen, oxygen

B. 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.

### What is a nebula?

• A.

A cold, dark, and dense cloud

• B.

A hole that sucks up everything near it.

• C.

A small planet that gives off red shifts

• D.

A warm bright cloud

• E.

Outerspace

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

• A.

Main sequence

• B.

White dwarf

• C.

Red Giant

• D.

Super Red giant

• E.

Black dwarf

E. 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.

### Which star colors have the highest surface temp?

• A.

Red

• B.

Green

• C.

Blue

• D.

Orange

• E.

C. 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?

• A.

Gamma rays

• B.

Spectral line

• C.

Creates absorption spectrum

• D.

Creates continuous spectrum

D. 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 is a black hole?

• A.

Sucks up everything that gets near it

• B.

Motional gravity pull

• C.

A spinning tornado in space

• D.

A worm hole

• E.

Time warp

B. 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 does the Doppler Effect tell us about things in space?

• A.

Universe is expanding

• B.

Universe is going to pop

• C.

Universe is contracting

• D.

Universe is getting closer together

• E.

How close all the planets are getting

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 do the Doppler Effect tell us about things in space?

• A.

Moves faster

• B.

Its expanding

• C.

Moves slowly

• D.

Its contracting

• E.

The planets shrink

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.

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

• A.

Reflecting telescope bounces off of things, while refracting bends light

• B.

Reflecting telescope goes througb space and back

• C.

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

• D.

Reflecting telescope uses a mirror, while refracting bends light

D. 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.

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

• A.

Hydrogen

• B.

Oxygen

• C.

Gravity

• D.

Main sequence

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 makes up 90% of the HR diagram?

• A.

Gravity

• B.

Protostar

• C.

Main sequence

• D.

Planets

• E.

Space

C. 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 light year?

• A.

Distance light travels in 5 minutes

• B.

Distance light travels in a second

• C.

Distance to get to a planet

• D.

Distance light travels in a year

• E.

Distance light travels a round earth

D. 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 is Chromatic aberration?

• A.

Chemical energy providing colors

• B.

Different colors is focused at different places

• C.

Light rays bendining, or retracting

B. 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.

### What do red shifts in our universe indicate?

• A.

Obects move towards eachother

• B.

Obects move away from eachother

• C.

Colder planets

• D.

Warmer planets

B. 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.

### What happens to wavelengths in Doppler effect?

• A.

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

• B.

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

• C.

Objects move towards or away from an object

• D.

Objects move towards other objects

• E.

Obects move away from other objects

C. 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 a Supernova?

• A.

An eplosion of stars

• B.

A giant planet

• C.

An explosion of planets

A. An eplosion of stars
Explanation
A supernova is a powerful and catastrophic explosion that occurs at the end of a star's life cycle. It is caused by the collapse of a massive star's core, resulting in a massive release of energy and the ejection of outer layers into space. This explosion is so intense that it can briefly outshine an entire galaxy and release vast amounts of heavy elements into the universe. Supernovae play a crucial role in the formation of new stars and the distribution of elements necessary for life.
