The expanding shell of gas shown here, called Abell 33, glows blue. It’s
the remnant of a dying star. The bright star that appears to sit on the
ring’s edge actually is nowhere near that shell of gas.

I like the way this article got right to the point in telling about the supernova. I think it's pretty funny that the star just happened to be so closely aligned to the ring to make it look like this. Also, hearing as the star is not actually next to the nebula but actually far away is interesting. It means that since the ring looks much bigger than the star just far away, it must be even bigger up close. Abell 33 must have been a powerful star to become such a large "dead star".
I found this article really interesting because of the fact that a star can be fueled for ten billion years. If a star, which is very bright can be fueled for ten billion years, why not the earth? In my opinion if we can capture the energy of a star in some way it could supply our planet with sufficient energy for billions of years as well. And since there are so many stars in the sky we could fuel our planet for many, many, many years to come. Overall I found this article very interesting and give it 9 out of ten stars for lots of information.
Oops! I posted the last comment before I finished. Anyway, I think that the article had an interesting idea about the "diamond ring" in space, but about half of the article was just explaining about how collapsing stars work, which I just happened to already know about. Even though I am sure this is still a learning opportunity for some people, I wish they had shared a little more about the actual topic of the article, which was the appearance of the ring in space. Maybe they could have mentioned the history of the star, the size of the nebula, or something like that. Overall, this article deserves 7 out of 10 stars.
I found this article interesting because I'd really like to read more articles about nebulas and "dead stars" really interest me. Even though I've heard this many times, it still surprises me that stars can "live" for 10 billion years! To answer your question JP, a reason for stars living longer could be that they are bigger and take more time to expand. This star lived for about ten billion years, but scientists predict that Earth will only live for 1.25-3 billion more years! I found this really interesting in the idea of the "diamond ring" in space and that coincidence of the linking makes it look nice, but there is still things to learn in this article too. Overall, I would give it a 8 out of 10 because it was interesting, yet short.
I thought this article was pretty good, because they gave definitions and background information on each topic. I am now clear on the definition of the supernova. The article was written about a 'wedding ring' in space, which is interesting. It looked cool too, but despite these facts, they could have written about something a lot more interesting that occurs in space: The sun looks like it is having a supernova when a large solar flare occurs, or that Kepler's search for habitable planets may have recently come to an end. What about Kepler's planet having a sunset similar to ours! Also, the earth and sun look like wedding rings when the sun rises. This article could have been better.
The first thing that caught my attention was that IT WOULD TAKE LIGHT THREE YEARS TO PASS FROM ONE SIDE TO THE OTHER of this blue "wedding ring". I think that that's crazy. Beyond crazy. WOW. I mean, do you know how fast light travels?! I really don't know what else to say. The whole article was really interesting. Every sentence I read made my brain bigger (not literally, but... you know what I mean). I might even become an astrophisicist when I grow up. Maybe. Overall, I'd give this article a 9/10. Only because I guess it could've been more fun... more kid-friendly. But otherwise it was pretty good.
I loved this article not only because it had an explained the nebula's start, but also because it focused on the fact that sometimes astronomical anomalies can be beautiful. The idea that Abell 33 had aligned with the other star brings me to wonder if they may have aligned when Abell 33 was still in its Mainstream years. I calculated that it would take 558 human years to cross the nebula that has formed. I cannot wait for the day that mankind figures out a way for humans to travel through the stars for so many years, or a way for a ship to go at the speed of light. How amazing that would be. Especially, if this state could be maintained for a long period of time. As they say in star trek we could use this technology "To seek out new life and new civilizations. To boldly go where no one has gone before!"
