Do You Know Your Constellations?

Explanation
The word constellation refers to a set of stars. It is used to describe a group of stars that form a pattern or shape in the sky as seen from Earth. Constellations have been named and recognized by different cultures throughout history, and they are used as a way to navigate and locate celestial objects in the night sky.

Explanation
There are currently 88 officially recognized named constellations used in the world. Each constellation represents a specific group of stars and has its own unique name and meaning. These constellations have been identified and named by astronomers over centuries based on their patterns and significance in different cultures.

Explanation
Certain individuals in the field of constellation work hard to simplify its understanding for others. The question asks about dividing the constellation, and the correct answer is 2. This implies that the constellation can be divided into two parts or categories.

Explanation
The correct answer is Southern and western hemisphere. This answer is correct because constellations are named based on their location in the sky. The sky is divided into different hemispheres - northern, southern, eastern, and western. The constellations visible in the southern hemisphere are different from those visible in the northern hemisphere. Similarly, the constellations visible in the western hemisphere are different from those visible in the eastern hemisphere. Therefore, the correct answer is Southern and western hemisphere.

Explanation
The large classical constellation of Agro Navis was broken up into 3 smaller constellations.

Explanation
The correct answer is Carina, Puppis, and Vela. The question is asking for the names of classical constellations assigned by the pioneering teams in the field. The given options are not relevant to the question. Carina, Puppis, and Vela are all classical constellations named by the pioneers in the field of astronomy.

Explanation
The question is asking for the term used to describe a constellation that is formed by different happenings in space, such as dark moon and full moon, rather than stars. The term for such a constellation is "Emu".

Explanation
Eugene Delporte is the correct answer because he is known for creating the authoritative map that demarcates areas of the sky under different constellations. This map, known as the "Delporte Celestial Atlas," is widely used by astronomers and is considered a significant contribution to the field of astronomy. Isaac Newton, Charles Darwin, and July Monro are not known for their work in mapping constellations or studying the sky.

Explanation
The correct answer is 1930. This answer is based on the information provided in the question, which states that there is someone behind sky demarcation and that an authoritative map was created to demarcate areas of the sky under different constellations. Since the question does not provide any additional information, we can assume that the creation of this authoritative map happened in 1930.

Explanation
De Lacaille studied the stars in the Southern hemisphere. Pascal, Newton, and other historical figures studied mathematics, space, and time to understand the mysteries of the universe. Since De Lacaille was mentioned in the same context, it can be inferred that his study of the stars would also be related to understanding the mysteries of the universe. Since he studied the stars, it is logical to assume that he would have done so in the hemisphere where the stars are visible, which is the Southern hemisphere.
