Blog 1: Asymmetry of the Moon
By looking at the image above, it’s clear to see that the dark splotches we’ve come to associate with our closest cosmic neighbor, the Moon, are only seen on one side! The farside of the moon is much more uniform with a lot more craters than the side we see. This stark difference has puzzled […] Continue reading

Blog 1: Scale of the Universe
It is difficult to truly grasp the size and scale of our universe. And while using units like light years might be helpful in some cases, it can also be helpful to put things in a scale that is more common in everyday life. This image helps me understand the scale of the universe in […] Continue reading
Introductory Post
By me – this is a photo of my sister and I at our favorite beach in Nantucket Island. This is where I first became fascinated with space; there is little light pollution here and for as far back as I can remember, I have stared at the night sky for hours at a time […] Continue reading
The Speed of Light
In 1905, Albert Einstein took the first crack at the Newtonian foundational physics. In his paper on special relativity, Albert Einstein postulated that the speed of light, c, is constant in all inertial reference frames. Assume that a person on a bicycle is holding a flashlight and moving at a constant speed relative to someone […] Continue reading

Blog 1
Imagine if the entire history of the universe could be squeezed into a single calendar year, providing a perspective of how much time has truly passed in this universe. Enter the cosmic calendar, a concept introduced by the astronomer Carl Sagan. Within the cosmic calendar, each month corresponds to over 1 billion years, allowing us […] Continue reading

The Vast Size and Scale of the Universe
BBC Science Focus The Universe is also used as a reference point to display somethings enormity. “I love you more than anything in the world” is massively trumped by “I love you more than anything in the Universe.” But what does this really mean? How much can the universe really hold? How big is it […] Continue reading

Blog 1 – Light Speed
The speed of light is a fascinating topic that has significance from everyday life to the vast expanse of the cosmos. The speed of light is the speed at which light travels through a medium, and for a vacuum, this speed has been defined as 299,792,458 m/s. This speed is almost incomprehensible to us due […] Continue reading
It’s not a phase, Mom! ⋆⁺₊⋆ ☾⋆⁺₊⋆
One thing I love about the nighttime is getting to see the different phases of the Moon in different times of its cycle. The Moon cycle consists of 8 phases as you can see in the picture below, and lasts 29.5 days, which is around one month! In this period, we see the Moon go from […] Continue reading

Humans and Light Speed
by me The speed of light is around 300,000,000 meters per second. It’s so fast that it can circle the Earth 7.5 times in one second. I always wondered if humans can ever achieve speeds the same as light, but we’ve only managed to go 176,462 meters per second with the Nasa Parker Solar Probe. […] Continue reading
Blog 1 – Solstices, Equinoxes, and Seasons
Traditionally, the Solstices mark the beginning of the most treacherous seasons. Being from Miami, when the summer solstice came around everyone always knew that the days would only get hotter. Once the winter solstice hit, we always prayed that there would be some form of respite (news flash, rarely was). Arguably, this is the worst […] Continue reading
