Some scientists called it an asteroid. Others theorized that it was an alien spacecraft. Still others cast it off as a mere “space cucumber.” This mysterious space rock known as Oumuamua (Hawaiian for “first messenger”) has captivated scientists since its discovery in mid-October of 2017. Oumuamua was discovered in Hawaii, hence its awesome name. This…
Ceres, the largest asteroid in the Solar System, and now considered a dwarf planet, may have once been habitable. NASA’s Dawn spacecraft collected samples from the surface and were found to contain organic compounds and amino acids, which are often referred to as the building blocks of life. Dawn has also discovered evidence of a subsurface… Continue reading Ceres Harbors Building Blocks of LifeContinue reading → Continue reading
We often misuse words such as meteor, meteorite, and asteroid while talking about space and not realizing that these three things are actually different! In this post I will explain the difference between all of them. What are meteors? Meteors are objects that enter the Earth’s atmosphere from space. Sometimes they are called “shooting stars”, […]Continue reading → Continue reading
243 Ida is a 56 km long asteroid orbiting in the main asteroid belt with a number of notable features. Ida is an S-type asteroid, or stony asteroid, and is mostly composed of rock and iron from accretion during early solar system formation. Ida was a subject of study by the Galileo spacecraft in 1993, … Continue reading Ida and Dactyl →Continue reading → Continue reading
We commonly think of asteroids simply as left over debris from when the planets were formed, but researchers believe that we will be able to harness resources from them within the next 10 years. The most common type of asteroid, C-type, contains up to 20% water as well as various metals. The presence of water […]Continue reading → Continue reading
I think one of the more fascinating topics in Earth’s past is the mystery of the dinosaurs. They were here 65 million years ago (for a shockingly long time—if you remember, they were here for almost a week in the “calendar” of the universe!) and then suddenly disappeared. So, what happened to them? It is […] Continue reading → Continue reading
Due to Earth being a terrestrial planet, much of our world’s material falls into the categories of rock and metal. An incredible motivator through humanity’s history has been our love of gold, silver, platinum and now other rare earth metals. We have been willing to blast open mountains and strip open land in the quest […] Continue reading → Continue reading
A comet is an icy Solar System body with very elliptical orbit that takes it close to the Sun on one end and far from the Sun on the other. When it gets close to the Sun it begins to outgas, forming a visible atmosphere called a coma and often also a tail. One noticeable […] Continue reading → Continue reading
The Chelyabinsk Meteor as seen by person driving a car right during explosion I watched another video and decided to watch one on the extinction of the dinosaurs. The video is very short and not absolutely thrilling but as I was watching the beginning of the video I thought to myself what if that was… Continue reading → Continue reading
Let’s talk about the dinosaurs. Everyone has heard the story: Dinosaurs roamed the Earth ages ago until an asteroid hit and caused all of them to go extinct. There was a huge amount of dust thrown up into the atmosphere which blocked out the Sun and caused plants to die. This set off a chain […] Continue reading → Continue reading
