Extremophiles are organisms on Earth that thrive in extreme environment that most other organisms wouldn’t be able to survive in. They are found in places that at a glance, seem unlivable, places like inside volcanoes, or deep in the ocean under extreme pressures. So why do these extremophiles matter when thinking about space? The ideaContinue reading “Extremophiles, and What They Mean For Life in Space” Continue reading → Continue reading
Gravitational waves are a fascinating concept. The thought starts from the idea that gravity moves at the speed of light. Now, at the start this sounds like a silly idea. Doesn’t the force of gravity always act on people? Yet take this example. Say the sun were to simply disappear. Not explode or change, butContinue reading “Gravitational Waves” Continue reading → Continue reading
Mars is a fascinating planet to compare to Earth, and much of that is due to the atmospheric differences. Most people know that due to the atmosphere on Mars, humans can’t live there, but what people don’t know is that billions of years ago, Mars had an atmosphere similar to that of Earth. Currently, Earth’sContinue reading “The Atmosphere of Mars” Continue reading → Continue reading
In the mid 1900’s, scientists were pointing radio telescopes toward the sun, the milky way, and other starts. In doing this they found small and extremely bright objects called Quasars. Over the next few decades, scientists had issues figuring out exactly what these objects were. It turns out that Quasars are caused by massive black […] Continue reading → Continue reading
In a previous post, I wrote about the Hubble telescopes revolutionary Hubble Legacy Field image. This ended the era of Hubble, which was the source of most of the discoveries of our solar system over the past decades. The new James Webb telescope is now set to be put into orbit in 2021, and itContinue reading “The Revolutionary James Webb Telescope” Continue reading → Continue reading
Spring Tides and Neap Tides: How the Angle of the Sun and Moon Directly Impact How Earth is Stretched
The size and fluctuation of tides are directly related to geography and the physics of various places around Earth. The average size of tides, however, rises and falls each month in direct correlation to the angle of the Sun and Moon in relation to Earth. These extremes are called spring tides and neap tides, andContinue reading “Spring Tides and Neap Tides: How the Angle of the Sun and Moon Directly Impact How Earth is Stretched” Continue reading → Continue reading
Many people have talked about the feeling of walking outside, looking up at the night sky, and feeling small. You look out into the cosmos, see seemingly countless stars, and think that everything you do on earth is just immeasurably small. Despite many people feeling that way, few truly understand the real scope of theContinue reading “The Universe is Incomprehensibly Large” Continue reading → Continue reading
It is a nearly universal maxim of science fiction that faster than light (FTL) travel must exist. Let us take a look at why this is universally necessary for the sake of a good story by comparing the size and scope of both our real universe and a few fictional universes to how long traversalContinue reading “Speed of light and distance” Continue reading → Continue reading
This past spring I interned at a company that developed educational documentaries about interesting topics such as nature, history, and space. The owner of this company had a history of creating planetarium footage, and he managed a successful YouTube channel called SpaceRip. This channel compiles fascinating footage of our solar system and explains many ofContinue reading “The Revolutionary Hubble Legacy Field” Continue reading → Continue reading
A new two-year long study done by the European Space Agency has created the most comprehensive survey of the universe ever recorded. The Gaia project has cataloged over 1.7 billion stars, 14,000 asteroids and numerous galaxies and galaxy clusters spread throughout the universe. What started out as a relatively small affair eventually exploded into a … Continue reading A new Stellar Catalog → Continue reading → Continue reading
