This is a question that I am having trouble with.

What are the benefits of different wavelengths for astronomy? (Infrared, X-Ray, Visible, UV, Optical, and Radio).

Help Please!!

Different wavelengths give different information about an object. By examining the wavelength of an object, you can learn properties about its temperature through Wien's Law. Different wavelengths can also tell you about what an object is made out of, because different gases emit different wavelengths of light. And since you won't know what the spectrum of wavelengths of an object is until you observe it, it's beneficial to observe across the entire spectrum of wavelengths.

Moreover, building telescopes for certain wavelengths helps to compensate for times when light at other wavelengths aren't available. It's hard to detect gamma rays from the Earth, so we observe at other wavelengths like optical and radio for our Earth-based observatories to account for that. Meanwhile, in space, it's too costly to build radio telescopes because radio telescopes are enormous; in this case, it's more feasible to launch gamma ray detectors, like the Fermi and Compton telescopes.

Thank you for your reply, but I was asking for the benefits of each individual wavelength!!

Hi, I was wondering, What are all the NGC numbers I need to know for division B Reach For The Stars? During an invitational, I found a few NGC questions that I did not have on my cheat sheet and just wondered, "What did I miss?"

the only questions should be about the DSOs on the rules or possibly one in its cluster or it interacts with, but that seems unlikely. if you go to each DSO's wikipedia page itll show the NGC, messier and common name which is all you should need.

I don't think you missed anything because they're only allowed to ask about dsos on the rules. But it's good to know how many dsos are in each catalog (Messier, NGC).
