We grew up here on this planet with […] Continue reading →

Like other electromagnetic particles, light has a specific velocity at which it travels. Further, it is presumed to be the fastest theoretical speed of any particle. The speed of light–referred to as “c” in a vacuum–is roughly 300,000,000 m/s. Since it moves so fast, most people never observe light as a moving particle or something […] Continue reading →

Scale and Travel Times

Posted on January 23, 2023 by dromalley

At this very moment, the Voyager 1 spacecraft is hurtling through space at about 61,500 km/h each and every hour, carrying it ever further from our Solar system which it left 18 years ago. But despite this staggering speed, it would still take Voyager more than 75,000 years to reach the nearest star, Alpha Centauri. […] Continue reading →

The Cosmic Calendar 🪐

Posted on January 23, 2023 by lightwyrs

“We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.” -Carl Sagan The Cosmic Calendar is a concept presented by famous astronomer Carl Sagan. In this diagram, the 13.8 billion year history of the universe is condensed into a […] Continue reading →

Blog #1: The Power of Ten

Posted on January 23, 2023 by reidwalker87

The Power of Ten video puts into perspective the miniscule size of not only individuals on Earth but of the Solar System entirely. At only 3 minutes into the video, we were already far beyond the Solar System with so much time remaining. Not only was I struck by the immense scale of the universe, […] Continue reading →

We Were the Closest To the Moon than We Have Ever Been

Posted on January 23, 2023 by thisisntzenon

As a child, I spent a considerable time looking at the Moon, and at one point, I may have even believed it was my friend. From the backseat of many late-night car rides, it “followed me”. In fact, during this period, my mornings consisted of watching Bear in the Big Blue House and the character […] Continue reading →

The Ultimate Race

Posted on January 22, 2023 by jackdoyle25

We take it for granted that the speed of light is the universal speed limit; nothing can go faster than light. The knowledge of light-years is crucial to understanding the images that we see in the night sky. These images are not of the celestial bodies as they currently exist, but as they once were, […] Continue reading →

The myth of travelling at Light Speed

Posted on January 22, 2023 by Liam Prescott

3*10^8 m/s. Wow. It’s practically impossible to conceptualize something moving 300 thousand Kilometers every single second, but believe it or not photons are doing this as we speak. To put this blistering pace into perspective, the distance from the North Pole to the South Pole is about 20,000 kilometers. Not even close to the length […] Continue reading →

The Incredible Size of Our Universe

Posted on January 22, 2023 by sahilreddy2

The image above is an artist’s illustration of everything in the observable universe. I find this image very interesting as it shows the scale increasing starting with our solar system and going out to galaxies, superclusters, our local group and further. This makes me realize how small we truly are in comparison to the universe […] Continue reading →

We Already Have a Time Machine

Posted on January 22, 2023 by araceal

People say time traveling doesnt exist. They are skeptical we are able to break every law of physics we grew up learning. But, if we really think about it, we have a time machine right in front of us: a telescope. What is a light year? Don’t be confused with the word ‘year’ being in […] Continue reading →
