So i have a physics presentation to do on tuesday and i have no idea how to find the temperature of a of objects in space, specifically the boomeran nebula. I did some research and found stuff involving black body radiation, wiens law, and stefan boltzman law but i dont really understand it too well.(adsbygoogle = window.adsbygoogle || []).push({});

Some of the things i dont understand:

wiens law states that wavelength(in meters) is equal to 0.0029/temperature(K). so is finding the temperature of the boomerang nebula really as easy as simply searching for the wavelength? is there a mathematical way to find the wavelength?

how can something so cold be so bright?

does the black body radiation curve have anything to do with this?

If none of this is the right approach to finding the temperature, how did they do it?

Any help will be greatly appreciated

thanks, melodyman888
