In general, the objects in the universe that are very high-energy objects, or the processes that are high-energy processes, will radiate more in the short wavelength range towards the gamma rays or the x-rays.
Claude NicollierMy first dream as a child was to become a pilot. My second dream was to become an astronomer, and I pursued in parallel efforts and studies in these two areas.
Claude NicollierAs far as the radio waves part of the spectrum, we can do these adequately from the ground because the atmosphere is basically transparent to our radio waves.
Claude NicollierThe objects that are of moderate energy, like our sun or most of the stars that we see in the night sky with the naked eye, are objects in which relatively moderate energy processes are taking place.
