Red Dwarf
- C.
Brown Dwarf
- D.
Blue Supergiant
Correct Answer
A. Black DwarfExplanation
A black dwarf is a theoretical end-state of a white dwarf that has cooled down to become 'black.' It emits no light or heat as it has no nuclear fusion activity.Rate this question:

- 3.
Which of the following stars has the shortest lifespan?
- A.
Yellow Dwarf
- B.
Blue Supergiant
- C.
White Dwarf
- D.
Red Giant
Correct Answer
B. Blue SupergiantExplanation
Blue supergiants are massive stars with very high surface temperatures. They are relatively short-lived due to their intense nuclear activity and quick consumption of fuel.Rate this question:
-
- 4.
The temperature of which star type determines its color?
- A.
Protostar
- B.
Neutron Star
- C.
Main Sequence
- D.
Brown Dwarf
Correct Answer
C. Main SequenceExplanation
The main sequence on the Hertzsprung-Russell diagram represents stars, like our Sun, that are in the stable phase of hydrogen-to-helium fusion in their cores. Their color depends on their temperature.Rate this question:
-
- 5.
Which star is characterized by its incredibly strong gravitational pull, from which even light cannot escape?
- A.
White Dwarf
- B.
Black Hole
- C.
Pulsar
- D.
Red Giant
Correct Answer
B. Black HoleExplanation
A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. It's formed from the collapsed core of a massive star.Rate this question:

-
- 7.
Which of these is not a phase in the life cycle of a star?
- A.
White Giant
- B.
Supernova
- C.
Main Sequence
- D.
Planetary Nebula
Correct Answer
A. White GiantExplanation
The term "white giant" isn't a commonly used classification for stars and doesn't represent a specific stage in stellar evolution.Rate this question:
-
- 8.
The Hertzsprung-Russell diagram plots stars based on their
- A.
Mass & Size
- B.
Luminosity & Temperature
- C.
Color & Size
- D.
Mass & Luminosity
Correct Answer
B. Luminosity & TemperatureExplanation
The Hertzsprung-Russell diagram (H-R diagram) is a graphical representation of stars' luminosity (vertical axis) and temperature (horizontal axis). It helps astronomers classify and understand stars.Rate this question:
-
- 9.
Which star has exhausted its nuclear fuels and collapsed to a high density?
- A.
Red Giant
- B.
White Dwarf
- C.
Supernova
- D.
Protostar
Correct Answer
B. White DwarfExplanation
A white dwarf is a dense, Earth-sized remnant of a star that has exhausted its nuclear fuel. It glows with residual heat and slowly cools over time.Rate this question:
-
- 10.
Which star is in the earliest phase of stellar evolution?
- A.
Neutron Star
- B.
Main Sequence
- C.
Protostar
- D.
Red Dwarf
Correct Answer
C. ProtostarExplanation
A protostar is a very young star that is still forming, typically within a stellar nursery or a region of space where new stars are born.Rate this question:
-
- 11.
The process of nuclear fusion primarily involves which element in a star's core?
- A.
Helium
- B.
Hydrogen
- C.
Carbon
- D.
Oxygen
Correct Answer
B. HydrogenExplanation
Nuclear fusion in a star's core primarily involves the conversion of hydrogen into helium. This process releases energy, which powers the star.Rate this question:
-
- 12.
What is a binary system where one mass is a neutron star or black hole and the mass transfer is so strong that significant x-rays are emitted?
- A.
X-Ray Binary
- B.
Spectral Binary
- C.
Visual Binary
- D.
Eclipsing Binary
Correct Answer
A. X-Ray BinaryExplanation
An X-ray binary system consists of a compact object (typically a neutron star or black hole) and a companion star. The compact object accretes material from the companion, emitting X-rays in the process.Rate this question:
-
- 13.
Which stars have a surface temperature below 3,500 K and shine with a dull, red glow?
- A.
Red Giants
- B.
White Dwarfs
- C.
Blue Giants
- D.
Red Dwarfs
Correct Answer
D. Red DwarfsExplanation
Red dwarfs are small, cool stars with surface temperatures below 3,500 K. They are the most common type of star in the universe and have a long lifespan.Rate this question:
-
- 14.

- A.
G-type star
- B.
K-type star
- C.
A-type star
- D.
M-type star
Correct Answer
A. G-type starExplanation
G-type stars, like our Sun, are classified as yellow dwarfs. They have a surface temperature of about 5,500 degrees Celsius and emit white or yellowish light.Rate this question:
-
- 15.
Which star is the remnant core of a massive star that has gone supernova?
- A.
Protostar
- B.
Neutron Star
- C.
Red Giant
- D.
White Dwarf
Correct Answer
B. Neutron StarExplanation
A neutron star is the collapsed core of a massive star that has gone through a supernova explosion. It is incredibly dense, with the mass of the Sun packed into a sphere only a few kilometers wide. Neutron stars are known for their strong gravitational fields.Rate this question:
