The instrument is sensitive to near - infrared light, the wavelengths at which the emissions of extremely distant galaxies — stretched by the expansion of space — shine most brightly.
WISE 0855 is too faint for conventional spectroscopy at optical or near - infrared wavelengths, but thermal emission from the deep atmosphere at wavelengths in a narrow window around 5 microns offered an opportunity where spectroscopy would be «challenging but not impossible,» he said.
Now, in a study published in Nature Nanotechnology on January 11th 2016 (online), a team of MIT researchers describes another way to recycle light emitted at unwanted infrared wavelengths while optimizing the emission at useful visible wavelengths.
Marengo said the study looked at two different infrared wavelengths: the shorter was consistent with a typical star and the longer showed some infrared emissions, but not enough to reach a detection threshold.
Okay, one little nit - picky issue with Q2 is that O2 and N2 actually DO absorb infrared radiation, just at shorter wavelengths than matter for the Earth's infrared emission spectrum (3 - 27 microns, with a peak around 9 microns or so).
A number of similar black hole exploration methods have also been proposed in optical / infrared spectra so far, but one crucial problem is that emissions at these wavelengths are absorbed by interstellar dust particles although the more active black holes contain more dust particles.
In practice, mono - atomic and symmetrical diatomic gas molecules have negligible emission / absorption at most wavelengths including thermal infrared.
