Our Earth, the Spinning Top?

What if I told you that in a couple thousand years from now, your Zodiac sign would no longer be your Zodiac sign? It may be devastating to devout followers of astrology, but the relative positions of the Zodiac constellations are changing very, very slowly, at least from our viewpoint. This is due to a … Continue reading Our Earth, the Spinning Top? Continue reading Continue reading

A Brief History of Precession

The priests of ancient Babylonia and Egypt were pioneer astronomers – they studied the sky, mapped constellations, and noted movements in both the Sun and the Moon – but, it was a Greek astronomer, Hipparchus, who made the first major new discovery in astronomy: precession. Comparing observations more than a century apart (particularly those done by … Continue reading A Brief History of Precession Continue reading Continue reading

Milankovitch Cycle

As we all know, the Earth experiences seasons each year. These are due to the tilt of Earth’s rotational axis, which causes certain areas of the earth to receive more direct sunlight during parts of the year, which has obvious effects on yearly climate. Interestingly, the Earth’s seasons also shift around on the calendar year. … Continue reading Milankovitch Cycle Continue reading Continue reading

Axial Precession and its Affects on Astrology

As the modern individual is likely well aware, the earth rotates in two very fundamental ways which affect our daily lives: it rotates every day and orbits the sun every year, forming these important means by which we keep track of time. However, one of the most interesting and confusing ways that the earth rotates […] Continue reading Continue reading

What’s Your Sign?

Ok… I’ll admit when I was younger I was really into astrology. It was a fascination fed partly by my mom, who kept around a copy of “The Secret Language of Birthdays” and would consult it regularly, nodding in solemn agreement with the book’s judgement of character. I had a horoscope app on my first […] Continue reading Continue reading

The Key Effortless Self-improvement

We’d all probably like to believe that astrology is real so we can identify with the redeeming qualities of our own sign and to hold fast to promising horoscopes. However, zodiac signs are not only false because of their vagueness, which allows each sign to at least partially relate to every human, but also due to […]Continue reading Continue reading

Identity Crisis

I have, apparently, been living a lie. My entire life, I thought I was an Aquarius, yet I have recently come to learn that my astronomical Sun sign is off by nearly a month. Because of the phenomenon of precession (the work of the gravitational pull and the conservation of angular momentum to correct the […] Continue reading Continue reading

Precession of Earth

I think one of the most interesting topics in Chapter 2 of the Astronomy textbook is about the concept of precession, or the gradual change in the rotational axis of Earth. The direction of Earth’s axis rotates on a 26,000 year cycle. That may mean next to nothing to us in our lifespan, but precession will gradually […] Continue reading Continue reading
