AI Thread Summary
Capturing star spectra for astronomical analysis involves understanding the temperature of stars, which influences their spectral output. To simulate star spectra, one can use different types of light bulbs that correspond to various star temperatures. However, for authentic star spectra that reveal composition, speed, and direction, specialized equipment such as a spectrometer is necessary. It is important to focus on stars with manageable temperatures for practical analysis. Achieving accurate results requires careful selection of stars and appropriate tools for observation.

I'm doing a project about astronomy. I've never done one, I just jumped from quantum physics to here, so I don't think I know anything =.=. To start, I think I need some stars spectrum, but since stars are not as bright as the sun, I don't really know how to have them. Could someone give me some advice of how to have stars spectrum (without using internet), and what equipment do I need...? Thank you very much ^^

The spectrum of a star is based on temperature. You can simulate it with light bulbs: do some research on the different types of stars and their temperatures, then compare them to different types of light bulbs and their temperatures.

There are stars that are millions of temperature. Exclude them before doing some simulation.
 
Thanks ^^. But I mean the real star spectrum where I can derive the composition of the stars, speed, directions... Is that possible...?
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
