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.

"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?

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?

Barred irregular
Obafgkm I think
K
Summer triangle
Supermassive black hole at the center of the galaxy
Infrared? I know I failed that one...
1054 ce

Sry if I spoiled it...

1. Thats what I would call them.
2. Those are spectral classes. The 5 luminosity classes I remember(at least I think), are Supergiants, Bright Giants, Normal Giants, Subgiants, and Dwarfs. I think thats them anyways, can someone confirm?
3. Yup
4. Yup
5. Yup, and I also think there is a supernova remnant somewhere in the structure as well( Its like SGT-A East or something like that)
6. Stangely enough, The thing I read said it was Infrared.
7. Yup

Yep, all correct, 'cept for 2. Mseq stars are luminosity class V (supergiants are I, bright giants are II, giants are III, subgiants are IV, and Mseq/dwarfs are V).

Additionally, on the Antares question, even if you didn't know the answer, you could have reasoned that since Antares is a red star, and red is the longest visible wavelength, it likely emits a large portion of its non-visible light in the next longest wavelength - infrared.

Now, did you guys answer all those without notes/google searches/other references? Because two years later, I can still do that. :P

Oh I confuse the two. And hypergiants are lum class 0.
No notes or google. And sagittarius a is the supernova remnants and stuff. Sgr A* is the black hole itself.
And main sequence is a star with an apparent relationship between temp and luminosity. (i.e. as temp increases lum does too)

I had to look up the light spectrum part, to be honest. Also, afterwards i went and double checked the Sagittarius A information i had.
