Are You Aware Of Stars?
Stars are what we see everytime and they're beautiful to a fault. So, what do you know about these beautiful entities that roam our universe.
- 1.
Which one is true in the following?
- A.
Our sun is far, far brighter than all of them
- B.
The stars are smaller
- C.
The stars we see are brighter than our sun
- D.
Stars are like smoke
Correct Answer
C. The stars we see are brighter than our sunExplanation
The correct answer is that the stars we see are brighter than our sun. This is because the stars we see in the night sky are typically much farther away from us than our own sun, and therefore appear brighter. Our sun is actually considered to be a relatively average star in terms of its brightness compared to other stars in the universe.Rate this question:

Once again, which one is true
- A.
You only see millions of stars on a dark night
- B.
You can't see millions of stars on a dark night
- C.
Stars do not exude heat
- D.
Stars are only green in colour
Correct Answer
A. You only see millions of stars on a dark nightExplanation
The statement "You only see millions of stars on a dark night" implies that stars are only visible in large numbers when the night is dark. This is because the darkness reduces the amount of light pollution and allows us to see the stars more clearly. In contrast, if the night is not dark, such as during a full moon or in a heavily light-polluted area, the number of visible stars may be significantly reduced.Rate this question:

How many colours do stars really have
- A.
5
- B.
Maybe 2
- C.
Most likely 4
- D.
1
Correct Answer
B. Maybe 2Explanation
Stars actually emit light in a wide range of colors, but to the naked eye, they typically appear white or yellow. However, when observed through a telescope or analyzed using spectroscopy, stars can exhibit a range of colors including blue, red, orange, and yellow. Therefore, the statement "Maybe 2" suggests that stars may have two main colors visible to the human eye.Rate this question:

Once more, which one is true?
- A.
Stars are gray
- B.
Stars are partially black
- C.
Stars are white bodies
- D.
Stars are black bodies
Correct Answer
D. Stars are black bodiesExplanation
Stars are black bodies because they emit a continuous spectrum of radiation, with the peak intensity occurring in the visible range of light. This means that stars emit light at all wavelengths, including those in the visible spectrum. The term "black body" refers to an object that absorbs all radiation incident upon it and emits radiation based solely on its temperature. Stars, being extremely hot, emit light across a wide range of wavelengths, making them black bodies.Rate this question:

Which one isn't a colour of stars?
- A.
White
- B.
Green
- C.
None
- D.
Blue
Correct Answer
B. GreenExplanation
Green is not a color of stars because stars emit light in a wide range of colors, including red, orange, yellow, white, and blue. The color of a star depends on its temperature, with cooler stars appearing red and hotter stars appearing blue. Green is not commonly observed in stars, which is why it is not considered a color of stars.Rate this question:

Our sun once more is a
- A.
Supergiant
- B.
Giant
- C.
Dwarf
- D.
White Dwarf
Correct Answer
D. White DwarfExplanation
A white dwarf is the correct answer because it is a small, dense star that is formed after a star has exhausted its nuclear fuel and has shed its outer layers. It is composed mostly of carbon and oxygen and is about the size of Earth but with a mass similar to that of the Sun. White dwarfs are the remnants of stars like our Sun and eventually cool down and fade away over billions of years.Rate this question:

Can stars actually be specifically counted? Yes, so, how many are there?
- A.
70 quadrillion
- B.
Uncountable
- C.
30 billion
- D.
780 trillion
Correct Answer
B. UncountableExplanation
Stars cannot be specifically counted because there are billions and billions of stars in the universe, spread across vast distances and in various sizes. It is practically impossible to count each and every star individually. Therefore, the correct answer is "Uncountable."Rate this question:

What's the composition of stars?
- A.
Lithium
- B.
Hydrogen
- C.
Helium
- D.
Sulphur
Correct Answer
B. HydrogenExplanation
Stars are primarily composed of hydrogen. This is because hydrogen is the most abundant element in the universe and provides the fuel for nuclear fusion reactions that occur within stars. These fusion reactions release immense amounts of energy, which is what makes stars shine. While other elements like helium, lithium, and sulfur may be present in stars, hydrogen is the main component.Rate this question:
