Space Potatoes!

(Diagram showing various asteroids, very potato shaped, you may notice) As Dr. G says, “When I say Asteroids, you say Space Potatoes!” But what exactly does that mean? The reason we liken asteroids to potatoes is because of their shape (unfortunately, they do not taste as good as those beautiful starchy tubers) (Side note: in […] 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

Mine

Gotteem. This ain’t about Valentine’s Day. Nor is it about Minecraft. Nor the seagulls from Finding Nemo. This is about asteroid mining. You’ve been jabaited. But stick around for the ride of your life, or well, a mildly exciting exploration of the next generation of mining. The Earth is limited in its resources, as we […] Continue reading

The Kuiper Belt: Exploring New Horizons

Hello (again), and welcome (back) to my Astronomy Blog! Today’s post is about the Kuiper Belt and its objects.  What is the Kuiper Belt?  The Kuiper (Kai-per) Belt is a donut-shaped region beyond the orbit of Neptune. Within the Kuiper Belt, it is estimated that millions of icy objects (or even trillions of these objects, […] Continue reading

What would happen if an asteroid struck present-day Earth?

We normally only see asteroids striking Earth in science fiction (what a relief!). NASA actually has an observatory whose sole purpose is to track both asteroids and comets and that appear like they might come close to Earth. During December of 2022, there were 5 asteroids that were placed on watch. Two of these asteroids […] 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

Asteroids and nucleotides | blog VIII

Just five days ago, researchers identified the last two nucleotide bases in asteroid samples that had previously been unrecognized. Professor and researcher Yasuhiro Oba at Hokkaido University in Japan, alongside a team of scientists, successfully identified the missing cytosine and thymine nucleases. Unlike the other bases, Cyt. and Thy. have very delicate structures, making them […] Continue reading

Nucleobases in Asteroids

Nucleobases are the building blocks of DNA and RNA. There are five total nucleobases (adenine, thymine, cytosine, guanine, and uracil) and three of the five have been found in meteorites. Recently, the last two nucleobases have also been identified. Th… Continue reading

Asteroid Mining

Picture of Asteroid With the current rise of privatized space travel, one industry that may very well likely be popularized within our lifetimes is asteroid mining. However the initial investment cost of getting to a profitable asteroid will be enormous, the payoff of mining and bringing back the metals that these asteroids contain would be …

Nuclear Weapons, Asteroids, and PHOs

Both nuclear weapons and asteroids are incredibly powerful and potentially dangerous objects with capabilities for mass destruction. The impact of the Chicxulub Asteriod about 65 million years ago had an explosive force about two million times greater than the Tsar Bomba, the most powerful man-made nuclear weapon ever deployed, which had an explosive power ofContinue reading “Nuclear Weapons, Asteroids, and PHOs” Continue reading
