Spring tides and Neap tides
Tides happen everyday, but there are certain types of tides do not happen everyday. The strongest tides and the weakest tides are called spring tides. Spring tides happen when the Sun and Moon are aligned, causing unusually strong gravitational forces and resulting very high and very low tides. Because it takes a month for the Moon … Continue reading Spring tides and Neap tides → Continue reading
Telescopes of All Kinds
Telescopes allow us to view the stars, planets, galaxies, and even quasars in great detail. Before the telescope, astronomers relied on naked eye astronomy, something Tycho Brahe was very good at. It’s really fascinating to learn how these telescopes work. Essentially, there are two types of telescopes – refracting and reflecting. Refracting telescopes use two … Continue reading Telescopes of All Kinds → Continue reading

Gravitational Waves
Up until recently, the only way we have been able to gather information about stars, galaxies, and the universe around us has been through the study of light. However, as of the last few years, the discovery of gravitational waves provides a new method of collecting information about the universe. Although gravitational waves were first … Continue reading Gravitational Waves → Continue reading

The Influences of the Moon in Astronomy and Astrology
When one looks up their horoscope in the daily paper, predictions are made based on the sun signs. One of the many things these horoscopes miss is the powerful astrological influence of the moon, which in some cases is stronger than that of the sun. It’s not just pop culture astrology that overlooks the moon; […] Continue reading
Gravity
Gravity is a fascinating phenomenon of physics that is integral to understanding the universe. Gravity keeps Earth in orbit around the sun, and the Moon in orbit around Earth. Any object that has mass, also has gravity. Moreover, the gravitational force between two objects is caused by two factors: mass and distance. The gravitational force … Continue reading Gravity → Continue reading

Blog 2: Mont Saint Michel Abbey Tides
The Mont Saint Michel Abbey was built in the 11th century on an island in Normandy, on the north coast of France. The island formed when the landscaped was eroded and granite outcrops remained. Medieval pilgrims nicknamed it, “St. Michael in peril of the sea” because of the extreme changes between high and low tides. … Continue reading Blog 2: Mont Saint Michel Abbey Tides Continue reading
How Big is the Universe?
Studies of the cosmic microwave background by the European Space Agency (Planck space mission) have revealed what we know as the observable universe, a sphere 28 billion light-years in diameter. Although scientists have placed the Earth in an observable sphere with a radius of 13.8 billion light-years, it is believed that this radius has expanded … Continue reading How Big is the Universe? → Continue reading
Wormholes
A wormhole is a theoretical tunnel connecting two points in space-time based on the theory of general relativity. Albert Einstein, Nathan Rosen and Ludwig Flamm are three physicists credited with hypothesizing this theory, but whether we will actually find one (let alone enter it) is largely up to debate. Warmholes are theorized to “pop-up” as tiny … Continue reading Wormholes → Continue reading
