All of the observations were obtained using a naked eye observation. One the first night of observation the sky was partly cloudy, and the moon was at the waning gibbous phase. It was 75° East and approximately 40° of arc from the horizon in the night sky. The angular distance from the Moon to the Sun was 154°.

The second night of observation the sky was clear. The Moon was at the waxing crescent phase. It was at 296° Northwest and approximately 20° of arc from the horizon in the sky. Due to its closer proximity to the horizon the Moons apparent size was larger than the Moon observed during the first observation. The angular distance from the Moon to the Sun was 39°.

On the third observation the sun was still out. The Moon was at the waxing gibbous phase. It was in the sky at 159° south and was approximately 40° of arc from the horizon. The angular distance from the Moon to the Sun was 142°.

The fourth night of observation the sky was clear. The Moon was at the waning gibbous phase. It was in the sky at 30° Northeast and was approximately 20° of arc from the horizon. During this observation the Moon’s apparent size was the largest in size than on any other night in observation. The angular distance from the Moon to the Sun was

There were many observations that the Greek philosophers made to support the idea that the Earth is round. First was the Lunar Eclipse, when the Earth lines up directly between the sun and the moon and casts a shadow on the moon. Second, they believed that since the sun casts shadows at different angles during the day, and…

of modern science. He was a major figure in Astronomy, Mathematics, and Physics, where he made many great contributions. Among these many groundbreaking discoveries, he was a pioneer in “experimental scientific method.” Galileo had five major observations in Astronomy which supported Copernicus’ theory of the heliocentric Solar System (2009, p. 609). These discovers where made through his own astronomical telescope in which he studied and observed the universe. Galileo pointed his telescope…

millions of years. There are some places in our solar system that are promising in terms of finding life. One of the most exciting places for housing extra-terrestrial life in our solar system is Saturn's moon Enceladus. At just about 314 miles in diameter, it's minuscule compared to Earth, which is nearly 8,000 miles across. Since it reflects nearly all the faint sunlight that hits it, Enceladus has a surface temperature…
