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
Blog Post 4 Chicxulub Impact
The Chicxulub Impact happened approximately 66 million years ago, defining the end of the Cretaceous Period and the beginning of the Paleocene, as well as the end of the Mesozoic Era and the beginning of the Cenozoic Era. This impact not only managed to eradicate the dinosaurs as the dominant lifeform on the planet but […] Continue reading
Making our Earth
New findings by the AKARI space telescope, coupled with surface modeling at the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology present new evidence that the asteroid matter which composes Earth was located much further out in the solar system than initially thought. Their study involved computer modeling to develop reflective spectra of hypothetical […] Continue reading

Han Solo Is Working Too Hard
While science-fiction flicks like Star Wars produce some exhilarating and high-stakes chase scenes with the help of treacherous asteroid fields/belts, in reality, you could probably navigate these asteroid belts blind-folded. With all due respect to Han Solo’s piloting skills and his less than twelve parsecs Kessel run, he would not actually have needed to utilizeContinue reading “Han Solo Is Working Too Hard” Continue reading

Deflecting Asteroids Headed to Earth
While the chances of a deadly asteroid hitting Earth are low, the damage that one could produce could result in a cataclysmic event. While it may seem that stopping an asteroid en route to Earth is impossible, there are actually certain technologies that could possibility lessen the damage. The most important thing to do isContinue reading “Deflecting Asteroids Headed to Earth” Continue reading
