Ecliptic

The moon phases are caused by the sun illuminating or lighting up one side of the moon. The sun is always illuminating one-half of the moon, depending on what place you are on Earth. That also affects what moon phase you see in The Lunar Cycle. The Lunar Cycle start with the New moon and then goes along to Waxing Crescent, Waxing Gibbous, then the Full moon. The cycle still continues on for Waning Gibbous Waning Crescent till it comes back to a New moon. This cycle continues about every 29 days…

Sarah O’Hara Phases of the Moon In this report, I will be explain how and why the appearance of the Moon changes over time. With some knowledge about phases of the Moon, I was able to learn a lot of valuable information through observations, group discussions, collecting data, and recording my findings. My report will answer the question “How and why does the appearance of the Moon change over time?” Methods of Collecting Data Throughout my observations, I was required to collect my data,…

When participating in this observation of the sky many things were brought to my attention. The sky has many mysterious things including the stars’ movement. I made eight observations where I live Del Mar Heights. Most of the descriptions of observation were an hour to complete. These observations over the semester from September to December were done with drawings I’ve below, I’ve noted any constellations that were visible I also used an astronomy website to name and understand what I was…

I have chosen the Andromeda constellation as my favorite because I have always loved the story of Andromeda. The constellation is named after Princess Andromeda, bride of Perseus from Greek mythology. She was used as a sacrifice to save her kingdom from a dreaded sea monster sent by Poseidon. She was rescued by Perseus who slew the beast. In mythology, Andromeda was the daughter of Cepheus and Cassiopeia, king and queen of the North African kingdom of Aethiopia. Her mother unwisely boasted…

The constellation I have chosen as my favorite is Virgo (The Virgin), for the simple fact that it is my zodiac sign. I do not know much about the constellation except for a few bits of information, like the fact that it is the second largest constellation that can be seen in the sky. The creation myths of virgo is another piece of information I know from previous research. Virgo is associated with a few different Greek and Roman myths of different goddesses. She is sometimes considered to…

According to Euclid’s definition of a geometric point, this claim is false because the planet earth has substance (however insignificant in relation to the heavens), therefore earth cannot be a point in the geometric sense. 4. Ecliptic The ecliptic is the path the sun appears to take through the heavens as a result of earth’s orbit. As we spin on our path around the sun, the position the sun occupies against the backdrop of the celestial sphere…

for finding the zodiac that the sun was positioned in. The Almagest also provided instructions on how to create tools for finding the positions of the moon and the sun. Ptolemy further created a catalog of the coordinates of stars based on the ecliptic, which is the path of the sun. Most of the coordinates written by Ptolemy were slightly modified versions of Hipparchus’s original coordinates. Ptolemy’s most influential scientific observation was his geocentric model of the universe, also…

Geocentric Model The geocentric model is a theory developed by philosophers in Ancient Greece which explained the universe structure where Earth is at the orbital centre of all celestial bodies. In the 4th century BC, Plato and Aristotle published studies based on geocentrism and believed that Earth was stationary at the centre of the solar system, and stars and planets rotated around the Earth on concentric spheres arranged in the order: Moon, Sun, Venus, Mercury, Mars, Jupiter, Saturn and the…

In our Solar System, the planets and the Sun sit inside a flat plane, called the plane of the ecliptic. This ecliptic is also the path taken by the Sun across the sky over the course of the year. There are twelve constellations lining the ecliptic. We know these constellations from our zodiac and the Sun passes through each of these constellations annually. Over time, this annual cycle of the Sun actually appears to move…

Astrolabes, an analysis in Islamic context Astronomical instruments from the ancient world were generally built upon various mathematical principles and hold much sophistication in their use and form. Back then, these instruments held much significance and were countlessly used in day-to-day life, since much of day-to-day life revolved around the sky and cosmos. One such instrument is the astrolabe. The astrolabe is an astronomical instrument that is considered to have originated from Ancient…
