A lie by citing the ices + dust paper with quote mining (pointed out by
tusenfem).
The paper is about Comet 67P outbursts.

The observation is

In addition, the measured large bolometric albedos (∼0.7) indicate bright grains in the ejecta, which could either be silicatic grains, implying the thermal degradation of the carbonaceous material, or icy grains. The 3 μm absorption band from water ice is not detected in the spectra acquired during the outbursts, whereas signatures of organic compounds near 3.4 μm are observed in emission. The H2O 2.7 μm and CO2 4.3 μm vibrational bands do not show any enhancement during the outbursts.
The albedos are from bright grains that can be
silicatic or icy or both.
