The Apollo 11 Quarantine
When Neil Armstrong, Buzz Aldrin, and Michael Collins returned from space after the Apollo 11 moon landing, they were immediately placed into a quarantine. This was the first manned mission to the moon, and the scientists weren’t sure if there would be any dangerous particles on the moon that the astronauts might bring back to […] Continue reading
some final thoughts
When I started this class, I didn’t expect to find so many connections between astronomy and they other subjects I’m interested in! I am majoring in philosophy and political science, subjects that I believed to be totally independent from the physics and history of our universe. Thankfully, I was very wrong! I still am shocked […] Continue reading
The Cosmic Microwave Background
One of the pillars that the Big Bang Theory Model rests on is the existence and characteristics of the Cosmic Microwave Background (CMB). The CMB is an observed cosmic glow of radiation seen everywhere, filling the universe like a sea. Roughly 380,000 years after the Big Bang, the universe cooled enough (~3,000K) for free-roaming electrons […] Continue reading
Bog 5 – Chelyabinsk Meteor
A relatively recent and frightening meteoric event occurred in the quaint city of Chelyabinsk in Russia on February 15, 2013. This incident is rather interesting since damage caused by the meteor was not due to impact, but rather violent shockwaves produced by the airborne-meteor’s explosion over the city. The explosion occurred when the meteor, roughly […] Continue reading
Blog #4 – Evidence for the Existence of Dark Matter
Dark Matter is a fascinating topic, yet we know so little about it. Regardless, a good amount of evidence exists that indicates dark matter is real. One pertains to the flatness of rotation curves for spiral galaxies at extended distances. The graph does not drop off, but rather, continues in (essentially) a flat rotation curve, […] Continue reading
Blog #3 – Theories For the Sun’s Energy Source
Many scientific theories attempted to explain the source of the Sun’s energy, and the very first hypothesis involved some explanation pertaining to chemical reactions and gravitational collapse. Chemical burning, however, was ruled since no chemically burning substance like wood or gasoline can account for the Sun’s enormous luminosity. As for gravitational collapse, the conversion of […] Continue reading
Where Did We Get Our Water?
We know that Earth is the only planet in the solar system currently capable of housing liquid water. The other planets are too low pressure or too hot for water to exist as it does on Earth. However, other bodies in the solar system do have solid water, also known as ice! The moon and […] Continue reading
Will The City of Angels Join The Angels? (Los Angeles Tectonics)
Image Source: https://images.app.goo.gl/ndxgiuzkinyLpxyZ8 The media, especially in recent years, has depicted that in the foreseeable future Los Angeles might break off of California and sink into the Pacific Ocean. Not only that but they also allude to the idea that this doomsday for the City of Angels may be completely impromptu as well. It is […] Continue reading
Powered and Unpowered Gravity Assists
The farthest planets in the solar system are so distant, it is infeasible to reach them using only rockets. The delta-v, or change in velocity, required to propel a spacecraft to a gas giant like Saturn is far too impractical for today’s rockets to achieve. The main problem is that a spacecraft needs tons of […] Continue reading
Blog Post 2 – The Doppler Effect
Most people have already heard of the Doppler Effect, an interesting phenomena of sound that alters the pitch of moving objects depending on their direction. The Doppler Effect functions similarly by affecting the shifts of light wavelengths. When, for example, a planet is moving toward us, its light waves will be clumped together and appear […] Continue reading
