Question and Answer
- Given the two photographs, the one which was taken last March 3, 2013 looks to have been taken at a higher altitude than the other. I am able to say this because it has more lines from the inner center to its outer lines compared to the other photo. In other words the higher the number of lines from the center, the higher the altitude used to take the picture. Also, the “March 3, 2013” photo shows shorter lines compared to the one that was taken last 2010. With that, I conclude that because of the wider scope of the subject, this photo - March 3, 2013 photo – exhibited was taken at a higher altitude.

This picture is from a higher altitude compared to the other two pictures because it has the shortest and most number of lines. It was taken in Bonaire, below the horizon and said to be 1000 steps towards north from the area.
- Provided the concept of declination system to give the location of an object, the star located at 80 degrees above my horizon will define my latitude on earth which is also 80 degrees at the Celestial Equator.

- Both the Altitude/Azimuth System and the Declination/Right Ascension System provides the location of an object in the space. Both give measurements which are definite and numeric. The two differs on how their system provides the location of the star or heavenly body. The Altitude/Azimuth System provides measurement in degrees based on the horizon and locates objects in space through the use of compass. On the other hand, the Declination/Right Ascension System provides measurement through exact coordinates. Ascension further provides locations through time expressed in minutes considering that time can give us estimates of distance.
- Constellations are sets of start which form patterns of definite and indefinite images in the sky. Examples are Cassiopeia and Orion - a mythological figure. In history, most of the constellations’ names come from the Greek gods and goddesses like those which I mentioned as examples.
- Star B will appear brighter that Star A which is given to be four times farther than B. The distance from the outer space to the earth further defines the brightness of a star. As we can see, the sun shines bright to the areas of the Earth and has become our source of heat because it is the nearest star to us and that because it is where the living planets surround.
- Given that the red star appears brighter than the blue star, then I conclude that it has shorter magnitude than the other. The red star will also look like it’s nearer to the planet Earth as it appears brighter than the blue one, and given the conclusion that it appears to have shorter distance than the other.
- Given the two stars which are of same distance from the earth and same size, their colors will matter as we define which will appear brighter. The red one will appear to be brighter provided that hotter star emit more light than the cooler one. With that, its distance relative to its brightness might be also concluded supporting that the red star is nearer to the earth than the other one.
