Today a spectacular “cosmic eye” was photographed in space by a telescope in Chile showing a far away nebula where sun like stars are burning themselves out. The image of the Helix nebula which is 700 light years away in the constellation Aquarius, was photographed by the Wide Field Imager at La Silla in the atacama desert.
The Helix is planetary nebula that is the closest planetary nebulae to the Earth but it is hard to see visually because light is spread thinly over a large area of sky. The main ring of the Nebula is about 2 light years across or half the distance between the Sun and the nearest star. Around the run you can see small blobs that resemble droplets of water which are know are cometary knows which have tails that extend away from the central star.

1. Review is very detailed and gives in depth information.
ReplyDelete2. Gives a good sense of the time frame in which these stars are located.
3. Explains the helix well.
1. Could have explained what a nebula is.
2. Could have said why this effects humans or any other kind of life.
1. I learned the helix is the closest star to earth and is actively burning itself out.
1 - just right amount of info - not too much not too little.
ReplyDelete2- easy to follow/understand
3- good explaining/describing for helix
1- A little short in length
2- need more info about other aspects besides the helix
1- I learned that helix is a planetary nebula that is hard to see with the naked eye
2-
3. i like how he gave specific details about the cosmic eye.
ReplyDelete2. He did a very good job of summing up the article.
1. This article seems very interesting.
2. He could have added a little more explanation.
1. HE could have added more information about the cosmic eye.
1. I was impressed by this article about the cosmic eye.
1. A great review with an obvious insight into the article.
ReplyDelete2. Shows the time cycle of stars and clearly presents the information.
3. Gives a great explanation of the helix.
1. A better explanantion of how this affects earth would be helpful.
2. Perhaps could have elaborated on nebula.
1. I learned that the closest star to the sun is about to burn out, and i hope the universe is not negatively affected.
1)This article provides a good amount of detail without being too specific
ReplyDelete2)Terms used such as "helix" were defined well and were understandable for the reader
3)Gives a good sense for the actual size of the Nebula because in the picture it does not look that big
1)He could have added a little more information on the Nebula's effect on earth
2)More information concerning what a Nebula actually is
1)I was impressed by this article and at how huge the Helix Nebula is
1. It was a good review of a short article that gives short but accurate and detailed information about the nebula and the "cosmic eye".
ReplyDelete2. He gave enough detailed information from the article to prove the point and inform us about what has been seen, and why it is interesting.
3. He goes into great detail about the helix, with a great explanation.
1. It would be helpful in understanding the article better, if he explained what a nebula is.
2. He could give more information and details supporting the article other then the helix. Besides the description of the helix everything was a little general.
1. I learned that the main ring of the nebula is about two light years across or half the distance between the Sun and the nearest star.
1. Gave a good back roumnd on the subject.
ReplyDelete2. Use definitions to help the reader understand.
3. Choose a interesting artical.
1.Could have described a nebula better.
2.Could have described a cosmic eye better.
1. I lerned a helix is aplanetery nebula.
1. Luke uses a lot of detail in his review and helps me get a better understanding of the topic with his explanations.
ReplyDelete2. He does a good job of describing the Helix and the importance of the photograph.
3. He gets to the main point of the article right away; a cosmic eye was photographed in space which shows a far away Nebula where the stars are burning themselves out.
1. Luke could have explained in the purpose for the photgraph.
2. He could have explained why this would be helpful to the earth.
1. I learned that the Helix is the closest planetary nebulae to the Earth but it is hard to see because the light is spread thinly over a large area of the sky.
1. The information wasn't overwhelming, he gave just the right amount.
ReplyDelete2. Gave a good explanation on what a helix was.
3. Explained thoroughly what surrounded the helix.
1. Could have given better definitions of what a nebula and a cosmic eye were.
2. The length of his review was a little short.
1. I learned that the Helix nebula is 700 light-years away.
1. High quality writing, Luke used good sentence structure and grammar.
ReplyDelete2. Luke chose an interesting article, nebulas are very interesting and beautiful
3. I like how he related facts like the diameter of the nebula and the distance from us to our closest star
1. Luke didn't describe things that we might now like how lengthy a light year is or even what a nebula is.
2. He should have given more information on the subject, the review is quite short.
1. I learned that nebulas in the universe can take all different shapes and colors.
