Chelyabinsk asteroid crashed in space before hitting Earth: scientists
Last year, a video of
an asteroid that had exploded over Chelyabinsk, Russia was released. This
asteroid left more than 1,000 people injured from debris and glass. New
research has shown us that this asteroid made contact with another asteroid
before reaching Earth. Jadeite, a mineral found inside the fragments of the
asteroid explosion show us that the body of this asteroid collided with another
asteroid. This collision could have easily caused the asteroid to separate from
its parent’s body and send it over to Russia. Shin Ozawa, the lead researcher
from the University of Tohoku in Japan, explained this all with a paper he
published last week. This discovery will help scientist understand more how
asteroids can collide and go towards earth. Also, they suspect this event to
have happened 290 million years ago. This fireball mostly destroyed due to
Frictional heating. This Frictional heating, traveling 60 times the speed of
sound caused a force about “30 times as powerful as the atomic bomb dropped by
the USA on Hiroshima.” Jade, the mineral found is only formed under extreme
pressure and high temperatures. This is the second most powerful explosion in
recorded history. This Asteroid is truly
a unique sample.
With the technology we
have today, we are now able to tell when an asteroid made its contact with
another object in space. This will help us determine what caused certain
asteroids to break apart. Also with the technology, we can tell when the event
took place. This will help us in the future with objects falling onto the
earth. We are able to calculate its precise path to earth as well. There could
very much be more information found in the remains of the asteroids, we just
need more time.
I think Irene Klotz did a wonderful
job of explaining the article and its content. She explained and described what
the mineral was and how it was found. She also gave background history with the
explosion (since it happened a year ago). The size of the asteroid and the
damage done was very much in detail. One thing I wished she explained more was
how they got the first event date. They just say how it happened 290 million
years ago. That is my question, How do scientists suspect an event (in this
case the asteroid) to have happened a certain amount of years ago and how
*(with what evidence)?
This is a very interesting topic to write about, and it made me want to keep on reading as well.
ReplyDeleteThree aspects that were very well presented was the amount of detail you put into the event, the scientists point of view on the asteroid, and saying your opinion on your article that you chose. I liked the way you presented the asteroid because you mentioned it was from new researches and how it broke off from its parents and collided with another asteroid, coming towards Earth and going right over Russia. Also, it was interesting how you mentioned the scientists point of view, saying it was more heated then the bomb dropped on Hiroshima, which was very fascinating to read about. Your opinion was very honest as well, saying what the author did that you admired and your question was very interesting as well.
Something from the article that really impressed me was that the scientists (from research) said it happened 290 million years ago, and this was impressive because it is interesting that they have the technology to determine the age of something the happened a while back. Finding the mineral (Jade) was another part of this that was impressive, and that it was in an asteroid in space.
I think that one thing that could have been better was the ending. I think you could have stated your overall opinion on the article in the last sentence. But this was very interesting to read and I hope to read more of this asteroid and what the scientists have covered while researching it.
Martin, you had an excellent topic to write about and did a fantastic job writing this article. The whole report was very well written and fluid in a way that was both easy to understand and interesting. The summary of the article had good key details and information on the topic. It was all written in a way where the facts told the story and needed few supporting details to further explain the topic. In addition, I also liked the quote you added in from the article to help cement your point. I have honestly never heard about your topic before and it was very interesting to lean about this new subject. I found the fact that the impact of the asteroid was the second most powerful explosion in recorded history, 30 times more powerful than the bomb dropped on Hiroshima. I was also interested by the fact that jade was found in this asteroid and the mystery surrounding how it was formed. The article and review were great however there were only a few weak points. I believe that the article could have had a couple more details about how the jade was formed in the asteroid as well as additional information on the collision of the asteroid in space. Other than that the review could have been a tiny bit longer but that really isn’t a large factor. All in all, the article and review were both fascinating and well done, good job martin.

I found this article very interesting. A lot of the information coming from this current event was new to my knowledge. i found it shocking how the the debris from the collision injured 1,000 people. I also found it amazing how if this collision were to separate from its parent body it would have been sent to Russia. In addition, I also thought it is useful and helpful using today's technology to stay aware of colliding objects in space. Overall i thought you did a good job summarizing this article up, and giving enough information to the reader. It would have been better if you had included your opinion and what you learned and found shocking from this article.
