The position of luminaries in the sky or points on an imaginary celestial sphere is described using celestial coordinate systems in astronomy. The horizontal coordinates, also known as azimuth and altitude, are the angular quantities that define the position of objects on the celestial sphere. These spherical coordinate systems do not consider distance and vary…
May 15 marked Astronomy Day in the spring of 2021. No scientific expertise or knowledge of the universe’s history is necessary to partake in the celebration.

When gazing up at the heavens, it is impossible for a person to accurately gauge the distance to the stars due to the lack of perspective in the sky. This is why ancient and medieval astronomers conceptualized the notion of a “sphere of fixed stars”. They imagined the stars as being affixed to a distant…
The Andromeda constellation is located in the northern sky, between Cassiopeia and Pegasus. Its name originates from the mythical princess Andromeda.
