Alright, new question:

How come people describe Abell 30 as "born again?"

What I got..|Well yeah, disregarding radius, but I'm getting 1.79x10^15 kg/m^3. Anyone else have any ideas? But in the meantime maybe I'll post a more mellow problem: A huge 4000-Kelvin tomato behaves like a blackbody. If Larcie Curbh, the astronomer observing this cosmic tomato, gets sick if she s...

I haven't seen the official rules yet, but the calculations can't be that difficult, can they? Nothing you can't find and learn easily on the 'net, I'd guess.

Alrighty I guess I'll put up another question k peeps: So there's this one early-age main-sequence star, Del B7730, with absolute magnitude 4.6 and apparent magnitude 10.2. Suppose you were (magically) able to line up a bunch of one-inch (diameter) strawberry gum-balls (melt-resistant, totally a thi...

[hide]That's gonna be 6740.33 F (or 4000 K, but you know) and it'll be on the Hayashi track. [/hide] (Yeah so my hide apparently doesn't work either) So what DSO is this, and what's the absolute magnitude of that bright star in the middle? http://www.lco.cl/telescopes-information/magellan/instrument...

The Shock Value wiki redirects to the Circuit Lab one. Also, just check the official rules for what you do/don't need to know. For example, it says that there shoudn't be questions about AC circuits and inductors, at least for the Circuit Lab event. So you technically can ignore it, but you might wa...
