I really, really need your help?

Question

Hey Everyone,
I'm currently an Earth and Space Science student and I am taking a virtual course. Unfortunately one of the resource sites that would've given me my answer will not open and "cannot be found". I told my teacher about it and she was basically like, "tough". So I need help with this one question or maybe a new resource site? Thanks!

Q:
Because we can't see through a gas cloud, we would not use optical telescopes which collect visible light to form images of stars inside a gas cloud. Which type of telescope would we use to study new stars inside the giant gas cloud and why?

Answer 1

Light scattering runs as the fourth power of frequency for Mie (molecular and atomic) scattering. The lower the observing frequency, the longer the wavelength, the less the scattering. Works for Rayleigh scattering (partculates), too, by diffracting around the foglets. Go into the IR or microwave.

If the gas is ionized, a plasma is opaque to electromagnetic radiation.

Answer 2

We could use Radio Telescopes to collect information on the stars within a gas cloud. Stars give off a wide spectrum of radiation from within their central cores where all nuclear fusion is going on. In many cases it is possible to detect that radiation as very high frequency radio noise. Success would depend upon the strength of those signals in comparison to noise from other sources in the nearby vicinity.

It might also be possible to do thermal imaging of the general area where these stars were located within the gas cloud. X Ray imaging and/or UV imaging are other possible solutions. The key here is to use what is provided. If there is radiation, try to study it and categorize it...how much, what frequency bands, what optical wavelengths, where is the cloud, what is the radiation generally from the cloud as compared to radiation levels from the nearby vicinity? All stars do not behave alike. There are differences and your mission might be to identify those differences and plot them in relation to other things around this cloud...then you are making progress.

Study, identify, categorize, compare, quantify, verify and report.

Answer 3

You would try to detect other forms of electromagnetic radiation to "see" inside the cloud. What you would be doing is detecting the emissions from the stars inside the cloud. The other forms of radiation you could choose to try try to detect are UV, IR, X-rays, radio waves. So, you could use an X-ray telescope, radiotelescope, etc.

Answer 4

either an infra red telescope or a radio telescope. either one can see wavelengths of light that pierce through the dust. that's how they study the center of the milky way
