What type of stars did Henrietta Leavitt discover?
- A.
Red dwarf stars.
- B.
Variable stars
- C.
Giant blue stars.
Correct Answer
B. Variable starsExplanation
Henrietta Leavitt discovered variable stars. This is evident from her work as a Harvard "computer" in the early 20th century, where she analyzed photographic plates of stars and found a correlation between the period and luminosity of certain variable stars, known as Cepheid variables. Her discovery revolutionized the field of astronomy, as it provided a way to measure distances to faraway galaxies and contributed to the development of the concept of the expanding universe.Rate this question:

What did Walter Baade find out that supported the Big Bang Theory?
- A.
Found out that the universe was double the size and age compared to what was originally thought.
- B.
He discovered the planet Uranus while looking out with a telescope.
- C.

Correct Answer
A. Found out that the universe was double the size and age compared to what was originally thought.Explanation
Walter Baade found out that the universe was double the size and age compared to what was originally thought. This discovery supported the Big Bang Theory because it provided evidence for the expansion of the universe. The theory suggests that the universe began from a singularity and has been expanding ever since. Baade's findings of a larger and older universe align with this idea of expansion, providing further support for the Big Bang Theory.Rate this question:

What does the Big Bang theory say the universe did first?
- A.
Cooled and expanded
- B.
Cooled and contracted
- C.
Warmed and expanded
- D.
Warmed and contracted.
Correct Answer
A. Cooled and expandedExplanation
The Big Bang theory states that the universe initially started as an extremely hot and dense point, and then rapidly expanded and cooled down over time. This expansion caused the universe to become less dense and allowed for the formation of matter and galaxies. Therefore, the correct answer is "Cooled and expanded."Rate this question:

What is a Pulsar?
- A.
Interactive star chart
- B.
Asteroid
- C.
Neutron star
- D.
Proton star
Correct Answer
C. Neutron starExplanation
A pulsar is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. As the star rotates, these beams of radiation are observed as regular pulses of light, hence the name "pulsar". Neutron stars are formed from the remnants of massive stars that have undergone a supernova explosion, and they are incredibly dense, with a mass greater than that of the sun packed into a sphere with a radius of only a few kilometers.Rate this question:

Correct Answer
C. Studying nuclear reaction that lead to the present elemental composition.Explanation
William Fowler won the Nobel Prize for studying nuclear reactions that led to the present elemental composition. This means that his research focused on understanding how nuclear reactions occur and how they contribute to the formation of different elements in the universe. His work likely involved studying the processes that take place inside stars and the role that nuclear reactions play in the synthesis of elements. This research is important because it helps us understand the origins and composition of the universe.Rate this question:

What was Christian Doppler's Theory?
- A.
A sun centered universe.
- B.
Stellar nucleosis
- C.
Thermal expansion of rheostatic polymerase
- D.
Apparant chage of freqency of a wave emitted by a moving source.
Correct Answer
D. Apparant chage of freqency of a wave emitted by a moving source.Explanation
Christian Doppler's theory is about the apparent change in frequency of a wave emitted by a moving source. This theory, known as the Doppler effect, states that when a wave source moves towards an observer, the frequency of the wave appears higher, and when the source moves away, the frequency appears lower. This phenomenon is observed in various situations, such as the sound of a passing ambulance or the redshift of light from distant galaxies. Doppler's theory revolutionized our understanding of wave behavior and has applications in various fields, including astronomy and medical imaging.Rate this question:

Lemaitre was pleased by the discovery of galactic redshifts that showed that galaxies were....
- A.
Not moving at all
- B.
Moving away from the Earth
- C.
Moving towards the Earth
- D.
On top of the Earth in a different dimension
Correct Answer
B. Moving away from the EarthExplanation
The discovery of galactic redshifts indicated that galaxies were moving away from the Earth. This is because redshift is a phenomenon where the light from distant objects is shifted towards longer wavelengths, indicating that the object is moving away. This discovery supported the idea of an expanding universe, which was a key component of Lemaitre's Big Bang theory.Rate this question:
