An amino acid is any acid that has an amine in it. They are not necessarily found in proteins. They can be found in conditions similar to deep space, for example: In a laboratory at NASA Ames Research Center in California’s Silicon Valley, the team of astrobiologists shone ultraviolet light on deep-space-like "ices," simulating conditions that are ...

@ProfRob 's answer helped me understand what is going on, but I would like to add something. If the telescope pointing is optimized for 5000 angstrom the aperture of 2" will completely contain an area of 1" that corresponds to 80% of the energy. If you keep the telescope pointing fixed, but trace the light at 3200 angstrom the "disk" of 1&...

I'm going to make the assumption that the "aperture" of the instrument refers to the width of a fibre that feeds a spectrograph (I can't think of any other plausible scenario). What you want is to enclose the most power you can within a 2 arcsec diameter in the telescope focal plane at the wavelengths of interest. One confounding effect is the ...
