I imagine there's quite some theoretical (software and chemistry) learning involved?
How would the image be captured live and get displayed in that graph...
(sounds expensive to me. one of those 4000$ CCD cameras??)
but once the mystery of capturing and reading the data is solved - the imagination can kick in.
this star is in a stage where it emits more and more such-and-such atoms. 
what if a planet in its vicinity by pure chance just now developed life forms? how would they evolve - directed by that particular chemistry that has dominated the area around the star for a while?
story lines form in my head. I'm no actual writer. but this stuff triggers a gene, apparently.
what do you "do" with the information you gather, Poita? |
Nope not expensive at all, you can even use a webcam, but I'm using a DMK21 which can be had for around $250 these days.
The software is inexpensive too, and there is a 30 day trial version. You should take the plunge it is an interesting diversion!
