What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
Did astronomers believe that the sun was part of earth?
No.
Is the iss always visible from earth?
Not ALWAYS, but if you are within 100 miles or so of its flight path during the hour or so before sunrise and after sunset, it's pretty easy to see; it's bright, and moving fast! You won't be able to see it during the day, or when it is in the Earth's shadow. However, astronomers have often been able to photograph the ISS as it "transits" the Sun. Check the links below for some astounding photos of the ISS taken by amateur astronomers here on Earth. You can go to the website spaceweather.com and check the times within the next week that it will be visible from your location.

How can an angle of isolation be measured?
An isotherm might have something to do with it--but it does not measure the angle of isolation. I guess that astronomers detect the angle of the earth from the sun and then measure the temperatures of the atmosphere. Just a guess though.
What is used when astronomers measure the distance from the sun to the earth?
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
