The correct answer is A. Heliocentric theory
Explanation:
Galileo Galilei was an Italian astronomer, mainly known for his observations that led Galilei to conclude planets revolve around the Sun (Heliocentric theory) instead of the sun and other planets revolving around the Earth (Geogcentrict theory). One of the observations that make Galilei drew this conclusion were telescopic observation of Venus, in this Galieli noticed similar to the moon Venus had different "phases" or changed its size and lighting, which was only possible if the sun was in the center of the solar system and planets revolve around it including the Earth. Thus, that Galileo was Venus changing size proved the Heliocentric theory.
Answer:
b) A series of stars that form a figure
Explanation:
In astronomy, <em>a constellation is any of certain groupings of stars that form an imaginary outline or pattern on the celestial sphere. </em>They are useful to track artificial satellites and in assisting astronomers and navigators to locate certain stars, therefore constellation is a series of stars that form a figure. A constellation can't be a region of the celestial sphere and all of the stars in it because not all stars in the celestial sphere form figures.
They are no figures in the night sky because constellations are starts, therefore they are present during day or night, it's not a term applicable to astrology because this is a pseudoscience not based on facts, like astronomy.
