How to determine elements based on received frequency from Space?

AI Thread Summary
Determining elements based on received frequencies from space can be achieved through spectroscopy, which analyzes electromagnetic waves. Users express difficulty finding comprehensive reference materials for identifying elements through spectroscopy, particularly for specific frequency ranges. A suggested resource is a website that provides extensive results for wavelengths, including a range of 4500-4600 nm. For detecting water (H2O) on Mars, specific frequency monitoring is needed, though the exact frequencies to target are not provided in the discussion. Overall, spectroscopy is highlighted as a key method for identifying elements in space.

I would like to know on how to determine the elements based on received frequency from Space?
Such as water H2O
Does anyone have any suggestions on where to find the reference materials?
Thanks in advance for any suggestions
 
Space news on Phys.org
Spectroscopy! Search on Google or Wiki for it and you should find loads of info.

It is hard to find any referrence library to search elements based on Spectroscopy, I find nothing with the first 2 pages of Google search.

I would like to know what the elements are on specific frequency of electromagnetic wave.

Does anyone have any suggested reference link? so I can look into it.

Thanks you very much for any suggestions
 
I found the following site, it seems to have a LOT of results. I typed in 4500-4600 for the wavelength range and it gave me about 500 results.

Thanks you very very much, it is a very good reference library

I get one question, if I would like to know whether H2O is present on Mars or not, what frequency should I monitor from Space?

Do you have any suggestions?
Thanks in advance for any suggestions

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
