Eclipses!
A solar eclipse occurs when the moon comes in between the path of sunlight and the Earth, casting a shadow on the Earth. Solar eclipses in general are quite rare (only a couple a year), but the moon’s shadow only covers a small portion of the Earth so seeing one is an amazing opportunity. AContinue reading “Eclipses!” Continue reading
The Astronomy behind Astrology
While astrology is widely disproven as a form of science in our modern age, it has its origins in the beginnings of computational astronomy. As explained by David Lindberg in his book The Beginnings of Western Science, “By the end of the fifth century B.C., Babylonian celestial divination had expanded to embrace horoscopic astrology, whichContinue reading “The Astronomy behind Astrology” Continue reading

Are We Really Andromeda’s Twin?
Astronomers have declared that our galaxy, the Milky Way is one of the largest two galaxies in our Local Group, rivaled only by its own twin, Andromeda. However, while technology has advanced greatly within the realm of astronomy, we have not yet reached the point of searching beyond the halo of the Milky Way andContinue reading “Are We Really Andromeda’s Twin?” Continue reading
Voyager Golden Record
The Voyager 2 is a space probe that was launched by NASA in 1977 in order to study the outer planets. It is still traveling and is now sending back information about the outer solar system and is around 13 billion miles away from earth. There is a record inside the voyager made to display […] Continue reading

The Universe is Incomprehensibly Large
Many people have talked about the feeling of walking outside, looking up at the night sky, and feeling small. You look out into the cosmos, see seemingly countless stars, and think that everything you do on earth is just immeasurably small. Despite many people feeling that way, few truly understand the real scope of theContinue reading “The Universe is Incomprehensibly Large” Continue reading
The Speed of Light and Gravity
We all know that light travels fast – 299,792,458 meters per second, to be precise. Still, if the sun were to suddenly disappear into a mysterious void, you and I on Earth would not notice for about 8 minutes and 20 seconds. Or would we? Would we not immediately feel the sudden jolt of ourContinue reading “The Speed of Light and Gravity” Continue reading
Zooming Out
One of the coolest videos I have ever seen is the Powers of Ten video. In 1977 Charles and Ray Eames—the inventors of the Eames Office, a famous furniture company—in collaboration with IBM, created a video beginning in Chicago and gradually zooming out, transporting the viewer to the outer edges of the universe. Every tenContinue reading “Zooming Out” Continue reading
How the Universe?
The universe is much, much, much bigger than you may think it is. I personally find it inconceivable – my finite brain does not register infinity. The observable universe, as we know it today, is 14 billion years old – this means that we can see 14 billion light-years into the universe. Within this universeContinue reading “How the Universe?” Continue reading
Infinite Possibilities
Upon reading this chapter, I was sort of disturbed by the reality of how infinite the universe is and how minuscule we are as humans (in the grand scheme of things). The Cosmic Calendar, a scale of the universe over the course of one year, reveals that humans would have appeared within the last fewContinue reading “Infinite Possibilities” Continue reading
Wormhole Theory
Reading about the vast size of the universe, I started exploring the possibility of travelling through the it. One popular theory on the structure of space-time is a wormhole. It postulates a theoretical passage through space-time that could create a shortcut to a different spot in the universe. So far, we’ve thought about travelling inContinue reading “Wormhole Theory” Continue reading
