Saving the Appearances

Strict Aristotelian cosmology follows that all bodies are made of the four elements: earth, water, air, and fire. These four exist in the terrestrial realm and the stars exist in the celestial realm. A fifth element, aether, exists there and that is what heavenly bodies are composed of. Aristotle provided the basics of the physics … Continue reading Saving the Appearances Continue reading Continue reading

Climate Change

Climate change is predominantly caused by the greenhouse effect, which is when gases in our atmosphere prevent heat from the sun from escaping the Earth. As greenhouse gasses continue to be added to our atmosphere (primarily by burning fossil fuels), the greenhouse effect becomes more severe, allowing less and less heat to escape from our … Continue reading Climate Change Continue reading Continue reading

Space Weather

In this post, we will be discussing space weather! Space weather is dissimilar from the weather that we experience on earth, however it is still fascinating to understand. Space weather, in our solar system, is sparked by activity on the suns surface. Spewing gases and solar flares on the surface of the sun form into … Continue reading Space Weather Continue reading Continue reading

The Mysterious Black Hole

The black hole is one of the most amazing and mysterious object in our universe. In 1916, Karl Schwarzschild first provided the solution to general relativity that characterize a black hole. Black hole is the remnant of super massive star’s explosion, and it has such a strong gravitational pull that nothing can escape, not even … Continue reading The Mysterious Black Hole Continue reading Continue reading

The Militarization of Space: What We Know Might Scare You. What We Don’t Know is Probably Even Worse.

What do you think was the first man-made object in space? Who do you think launched that object? It may surprise you to find out that the first man-made object to reach space was a V-2 rocket launched by Nazi Germany in 1944. Fortunately, the Third Reich was defeated before their successes in rocketry could … Continue reading The Militarization of Space: What We Know Might Scare You.

Interplanetary Rocket Travel and the Rocket Equation

In rocket travel, one of the most essential elements is ∆v – the change in a ship’s velocity. The spaceship needs to accelerate to get out of the atmosphere, and then speed up to achieve orbit. If it’s going to another planet, it needs to achieve escape velocity from Earth, then speed up/slow down its … Continue reading Interplanetary Rocket Travel and the Rocket Equation Continue reading Continue reading

Blog 4: Humans back on the Moon and on to Mars

NASA’s plans for sending people to Mars are intertwined with their plans to send humans to the Moon more consistently, and hopefully to be able to establish a human presence their within the decade. They plan to launch the Gateway, a spaceship that will orbit the moon to support future trips there. They plan to launch … Continue reading Blog 4: Humans back on the Moon and on to Mars Continue reading Continue reading

Titan

Titan is one of the biggest moons in the solar system, and is the most similar object to Earth. The icy world is second in size to Jupiter’s Ganymede and is larger than the planet Mercury. Titan is very unique in that it is the only moon to have a dense atmosphere. Like Earth, the … Continue reading Titan Continue reading Continue reading

Voyager: The End of the Road

Voyager 1 is the only human made object existing outside of the heliosphere of Earth. The Voyager space probes represent a level of exploration not seen since the era of European explorers, and in many ways exceed the ambition of those brave individuals. Aspects of the Voyager mission have been designed to last for an … Continue reading Voyager: The End of the Road Continue reading Continue reading

Oort Cloud!

I kept hearing about the Oort Cloud during this unit, so I wanted to do some more research on it. The Oort Cloud intrigues me because it is theoretical, meaning that we have not actually observed it empirically. In my last post, I talked about the Voyager missions. In another 300 years, the Voyager space … Continue reading Oort Cloud! Continue reading Continue reading
