That is interesting. I had to look up what a spectrograph is. I am guessing it can tell what something is made of from many miles away.

Sort:  

It analyses the light reflected from, or passing through, a material to detect which spectra are absorbed to reveal the elements of that material. It's also how astronomers can tell if exoplanets around distant stars might have a breathable atmosphere.

The things they can do are amazing
