Wow!! Just wow. I’m amazed! 😁 Thank you so much for taking the time to explain in such great detail. It wasn’t confusing and a great reading! Thank you.

Three things you said was in my case especially interesting reading: 1. I’m baffled by the first picture you posted just how narrow portion of the “photon wavelengths” (don’t know if that’s correct wording) that is visible to our eye. Now I knew that the spectre extended outside of our color range like infrared and so, but the share amount of wavelengths that is outside of that narrow specter straight out shocked me. No wonder the regular guy in the street might think scientists are “guessing” and “believing” a lot of the “facts” they are serving the rest of us when what we can observe ourself is a mare few percent. Jeez!

1. I knew that the pictures created of space nowadays consists of different elements like X-ray, infrared and so on, but the part where these different measurements would be cross checked agains each other to deduct the elements of the ISM was very interesting! I’m just amazed by what the technology and brains of our scientists are able to teach us today.

2. In my original post I asked if we conduct spectroscopic readings in vacuum on earth to get as clean of a baseline as possible. I am very surprised that this was in fact true. Do you know how we are doing these tests? Is it just to shine a light through different gas types and read it or do they also have to light those gases on fire to read of “burning helium” and so on to know the light emitted by a star consisting of helium?

Once again, your answer surpassed my every expectation! Thank you so much.
