Comment Slightly skeptical - instrument bias? (Score 1) 88
I'm slightly skeptical - and hopefully my skepticism can be easily answered. But my skepticism has to do with measurement biases.
I read what I could of the scientific publication, but I'm not experienced at reading these things - so I'm also skeptical about my skepticism. My thoughts range around the following:
- [A] Differential aging between the masked (covered) pixels and the exposed pixels over time
- [B] Whatever cloud of stuff surrounds New Horizons - expelled maneuvering propellant, off-gassing of plastics, etc. reflecting light from the sun.
- [C] Low level noise effects from other EM-spectrum that might be affecting the sensor at the extreme low levels of measurement involved here.
I would think that these would at least be considered by the researchers and taken into account. This kind of stuff seems like pretty basic concerns to me - largely covered by accurately calibrating the instrument (the telescope.)
In the meantime, I'll take a bit of childish (and ignorant) joy in mumbling dark light to myself.
