Lunar and Solar Tides
Tides are a fascinating effect of the Moon and Sun’s gravitational forces acting on the Earth. They are a visible sign of how distance effects the strength of a gravitational force. Because the Sun is so large, it has the greatest gravitational force acting on the Earth. However, because it is so far away, the […]

Limitations of Gravitational Slingshots in our Solar System
The use of gravity assist has been an integral part of space exploration. Gravitational slingshots have been used time and time again to send spacecraft to areas that would be impossible to get to otherwise by providing the spacecraft with increased speed. Accordingly, spacecrafts are able to get places faster and use less fuel. (Voyager […]

We’re all attractive (by gravity!)
We like to think science has everything figured out—and it has in fact come very far to that end. But there are still many things in the world and the universe that has researchers scratching their heads. One of these phenomena is gravity, the force that attracts all objects. Sure, we know how to calculate […]

HW #B3 – A Superpower Redefined
Be it an elementary school sleepover or a university orientation, there’s always a place and time for the infamous question: If you could have any superpower, what would it be? Some people say they’d love to fly or breathe underwater, but one of the most popular answers is X-ray vision. The entire process behind X-ray […]

Spectra Across Spectral Types
One of the beautiful aspects of the universe is that not every celestial object is exactly the same. The majority of stars spend their lives on the “main sequence” in which they have stable volume and continuously undergo hydrogen fusion. Astronomers use a classification system based solely upon the temperature of a star, assigning each […]

Tides can be Fun(dy)
Anyone who has spent the day at the beach has experienced the changes of the tides. Few of us, however, have ever seen anything like the Bay of Fundy, a body of water between New Brunswick and Nova Scotia in Canada with the largest tidal range in the world. Within twelve hours between low and […]

Why do we have tides?
Today I want to talk about tides! Above is this video of Clovelly, England and the drastic tide that they experience day in and day out, especially when it is spring tide, meaning the moon and sun’s tidal forces line up to create even more drastic tidal forces. What is amazing about that video is […]

Mayan Astronomy
At the end of 2012, the whole world was abuzz with the news that on December 21st, the Mayan calendar would end. Some claimed this ominous event signaled the end of the world, while others simply suggested the Mayans would have likely extended their calendar if they were still around. Who Did It Better: […]
