There are a lot of theories on how the Moon came to being. But one of the most accepted theories is that it was formed from debris that resulted from a collision between Earth and a Mars-sized body called Theia. This collision caused a big chunk of mass to eject from Earth which later on cooled down and then became the Moon.
Our Moon, which is the fifth largest Moon in the Solar System, was given names by several cultures and tribes, one of which is “Bulan” given by the Malays, which is close to how Filipinos call the moon as “Buwan”. Because the Greeks named it “Selene” a titan and their moon goddess, the study of the Moon’s geology is called Selenology.
You might wonder why the Moon looks different every night. This is because as the Earth revolves around the Sun, the light reflected to the Moon varies everyday. This phenomenon creates the phases of the Moon.
Because our Moon is massive, its gravitational pull affects bodies of water during certain phases. This affects the tides, but most importantly the lives of people living near the bodies of water.
Tides and Their Effects on Fishing
Due to the combined gravitational pull of the Moon and the Sun, tides occur. Still the Moon is the major force behind tides because it is nearer to the Earth. Tides are periodic short-term changes in the height of the water surface in a particular place.
During the falling fide is the best time of day to catch fish. This occurs when the tide changes from high tide to low tide. The faster the water is moving out, the better the fishing. This is because the fish take advantage of this time to feed on the smaller fish being pushed out to the sea. Meanwhile, high tide is not ideal for fishing because of the rise in sea level.
Tides affect, not only fishing, but also sea travel. Just before a low tide occurs, sea vessels are moved to shallow spots to avoid them from getting hauled into the coastlines. Many marine animals and plants also benefit from the tides. The daily ebb sweeps nutrients from the shallows, moving the juvenile fish from seashore nurseries to the deep ocean.
The pulling of the seas toward the Moon not only affects seawater depths along the coasts, but also the Earth’s rotation, slowed down by what is called tidal friction. The movement of the bulge of tidal water across the oceans and its attraction to the Moon acts as a brake on the Earth’s rotation. As a result, the length of a day increases.
Perhaps the most important effect of the Moon is the way it stabilizes our rotation. When the Earth rotates, it wobbles slightly back and forth on its axis. Without the Moon, we’d be wobbling much more.
Psychological Effects of the Moon
From the word Luna, the Roman Goddess of the Moon, the word “lunatic” was formed. Since the phases of the Moon have a great effect on the bodies of water, Greek philosopher Aristotle suggested that because the brain is the “moistest” organ in the body, it is more susceptible to the pernicious influence of the moon. Agreeing to this is Miami psychiatrist Arnold Lieber who conjectured that since the human body is about 80% water, the moon works its mischievous magic by disrupting the alignment of water molecules in the nervous system.
This is why strange mass behavior is attributed to the presence of a Full Moon. In Europe during the Middle Ages, “Lunar Lunacy” was also known as the “Transylvania effect”, wherein some believe that certain humans transformed into werewolves or vampires during a Full Moon.
Even today, the Full Moon is associated with strange events, such as increased cases of suicides, homicides, psychiatric hospital admission, emergency room calls, traffic accidents, local fights, and animal bites.
Sleep Deprivations
A small study in 2013 by Chrono-biologist and Sleep Researcher Christian Cajochen at the Psychiatric Hospital of the University of Basel in Switzerland was conducted. Out of 33 volunteer adults, all of them slept less during the Full Moon even when they were not aware of the current lunar phase. But a year later, a broad review of sleep-moon research done by scientists at the Max-Plank Institute of Psychiatry in Germany, found no statistically significant correlation between lunar cycle and sleep.
More recently, a research was published on March 2016 by the Frontiers in Pediatrics from the Children’s Hospital of Eastern Ontario Research Institute in Ottawa, Canada. More than 5,800 children aged 9 to 11 were analyzed in 12 different countries. The children about 5 minutes less on nights with a Full Moon. This is “unlikely to be important” from a health perspective, the researchers said, but is definitely interesting. Though the brightness of the Full Moon may be the reason for the decreased sleep, researchers doubted this suggestion because of the proliferation of artificial light these days.
Suicides and Homicides
There have been reported cases of an increased crime rate at an event of a Full Moon. A study was conducted in India on 1978 to 1982 by Dr. Siraj Misbahm a neurologist. He randomly selected 3 police stations—one rural, one urban and one industrial in Bihar, Northern India. These three police stations are at least 300 kilometers apart. Gathered data suggested that crimes committed on Full Moon Days were much higher than on all other days.
Psychiatric Hospital Admissions
A study in 2014 led by Varinder Parmar of Queen’s University in Ontario, Canada looked at psychiatric emergency-department visits 6 hours, 12 hours and 24 hours before and after a Full Moon. During the 6 hours before and after a full moon, data showed significantly more patients with personality disorders as well as those who needed more urgent care were admitted to the hospital. However, fewer patients with anxiety disorders showed up during the 12 hours and 24 hours prior to and following the Full Moon.
We cannot argue that the Moon plays an important part in our daily lives. A lot of mysteries have yet to been proven about our satellite but until then, take time to appreciate its beauty and its many phases.

What is the origin of the universe? This was the question that piqued my curiosity and inspired me to study the immensity of space and time. This inquisitiveness fueled my passion for the universe and the unlimited dimensions it held. Everything about it fascinated me: how it worked, how it grew, and many more. I fell in love with the idea of endless discovery.
When I was in grade school, I attended an event entitled “Astro Camp”, where I was given a chance to peek into a telescope for the first time. This was how my love for astronomy began.
When I was in my last year in high school, when my batchmates were critically eyeing the courses they wanted to pursue, I was already certain that I should follow my second love, education. Because of monetary problems, I was willing to relegate my love for astronomy to the backseat. Since it’s not a typical field of study here in the Philippines, limited jobs are offered after graduation.
I tried to submit an application for my college admission at the Philippine Normal University to study education. Unfortunately, when I arrived there, I found out they no longer accept applicants. Then I went to the Rizal Technological University (RTU) – the only institute that offered BS Astronomy at that time – to pursue what I really wanted. Despite having limited cash for my daily trips, I strived to reach my goal. After a month of battling with life’s uncertainties, I finally got in.
I believed that the risk I took was a blessing in disguise. In my early college years, I joined different events which allowed me to expose my talents and abilities. I grew as a person and developed my innate proficiencies such as leadership and confidence. Learning astronomy is not easy unless you have the desire to study it. I firmly believe that whatever course you choose, as long as you really love what you are doing, everything else will fall into place.
BS Astronomy is not just about fascination with the cosmos, it also has its practical use. In our earlier years in this program, we studied the subject, “Solar System,” where comparative planetology was discussed. We analyzed the weather systems in different planets and their capabilities to host life. Detections of exoplanets – planets outside the solar system – was also discussed. Scientists nowadays are keen to find out other places in the universe where life can possibly thrive. Astronomers are also finding ways to prolong the existence of life on Earth. Hence, we have a meteorology subject that deals with the study of the planet’s weather systems, including climate change and disaster awareness.
As the country’s pioneering institute that offered a degree in Astronomy, RTU had only three graduates in its first batch. The University’s department of Earth and Space Sciences (DESS) was established by Dr. Jesus Rodrigo F. Torres, the Vice President for Academic Affairs at that time. Together with recognized physicists, chemists and other scientists passionate about astronomy, they formally introduced the BS Astronomy Technology to the RTU community in 2007. Two years later the RTU-DESS has its very own student organization, the RTU-Astronomy Society, dedicated to spread the idea and exquisiteness of space. The RTU-DESS used to send students to different international activities and seminars annually. Its members also organized outreach programs that aim to disseminate facts and information about astronomy to the public.
Last school year, in 2015, the New Era University (NEU), located in Quezon City, also introduced astronomy to their academe. NEU experienced the same struggle RTU encountered: due to the small amount of people who knew about astronomy, there were only few students who enrolled in their program. In spite of this, I remain hopeful that in the near future, astronomy will be a well-known course in the Philippines, and that more young people will be captivated by the mysteries it offers.
When I graduate next year, in 2017, I want to pursue my studies in astronomy by obtaining a scholarship in a master’s degree program. I would like to see myself in my late 20’s as a doctor of philosophy in the field of astronomy, and to be an educator in the different universities here in the Philippines. This way I will finally able to meld my two loves: astronomy and education.
It is true what they say about learning, that it never ends. I still may not know how the universe began, but the process of exploring the answers is one that I will never tire of.
