One: scientific american is commonly an oxymoron outside of scioly.
Two: I don't suscribe 2 it.
Three: can you send a link to the diagram if possible?
The H-R Diagram is not included in the online content. But I've heard of these really strange places where you can get Physical Copies of Books and Magazines. I think they are called "Libraries" and there is this other place that I've heard called a "Book Store".

Um shouldn't the hr diagram thing be in astronomy not solar system?

Astronomy is a Div C event, and way more in depth that Reach for the Stars. Since my target audience is middle schoolers who will be switching from Solar System to RFS, I put the info in this thread.

I saw that issue of SciAm, and since I'm writing an RftS test right now, my first reaction was, "Holy [butterfly], this is perfect for the test I'm writing!"

Cheesy Pie: I've actually seen a lot of H-R diagram stuff on RftS tests. It's pretty typical for a RftS test to ask competitors to identify what kinds of stars are in specific places on the H-R diagram, or to plot stars on a blank H-R diagram.

IMO, Astronomy is pretty much RftS but harder and more in depth. the basic things still remain the same, such as galaxies and HR Diagrams, etc.

Speaking of magazines, did anyone see the magazine article from nationals (Solar System) before the test? (As in, did you actually see the article in the magazine?)

It's the most awesome event ever. ;)

Basically they give you a list of constellations, stars and DSOs (things like nebulas, galaxies, and star clusters) that you should know information about, and you should be able to identify constellations and/or DSOs from images. You should also know general information about the topics in the opening description, which for 2009 were "stellar properties, stellar evolution, open and globular star clusters, and spiral, elliptical, and irregular galaxies."

I have a friend whose sister really liked this event. It's about stars and deep space objects. I don't know much because I've only been around the Science Olympiad for one SO season.

And in Solar System, they actually put questions about stars from other solar systems. It's the Solar System. Do they really not understand?

Really? Where? I've never taken a test with stars from other solar systems in the various Solar System tests Ive taken...

Scarsdale. Our "B" team failed and they guessed for every single question. My microbe mission partner was one of them.

Anyway, your avatar is no longer a picture of Saturn (location).

Huh. So I guess your States/Regionals test didn't exactly follow regulations.

Changed :P

"Sol" is Latin for Sun. So, technically, there is only one SOLar system. There are many planetary systems, but one Solar System.

I personally like the term Extrasolar system for other planetary bodies and their companions.

I also saw the scientific american issue, and it quite wonderful. When i did this as my first event (somewhere in the neighborhood of 8 years ago), The HR diagram came in very handy. In fact, it got me my first medal. :D

Wait - is there solar system next year? If so, let's quiz each other too! Make sure to mark whether you're quizzing us or you don't know the answer. Are you ok with this?
What is the farthest known Plutoid? (Quizzing you)

No, Solar System's gone and Reach for the Stars is returning. Didn't we just cover this at the top of this very page?

Care to try some RftS practice questions? Courtesy of my as-yet-unfinished practice test. :twisted:

1. What shape galaxy are the Large and Small Magellanic Clouds typically considered to be?
2. What luminosity class are Main Sequence stars on the H-R diagram?
3. What class star is Aldebaran? (O, B, A, F, G, K, M) [Sorry, I just had to put this question.]
4. What famous asterism is formed by the three stars Altair, Deneb, and Vega?
5. What is Sgr A* and where is it located?
6. Antares (a Scorpii) emits a large portion of its energy in what non-visible wavelength?
7. In what year was the supernova that created the Crab Nebula visible from Earth?
