WASP-104b is Darker than Charcoal

By analysing the K2 short-cadence data from Campaign 14 we detect phase-curve modulation in the light curve of the hot-Jupiter host star WASP-104. The ellipsoidal modulation is detected with high significance and in agreement with theoretical expectations, while Doppler beaming and reflection modulations are detected tentatively. We show that the visual geometric albedo is lower than 0.03 at 95% confidence, making it one of the least-reflective planets found to date. The light curve also exhibits a rotational modulation, implying a stellar rotational period likely to be near 23 or 46 days. In addition, we refine the system parameters and place tight upper limits for transit timing and duration variations, starspot occultation events, and additional transiting planets.

WASP-104b's albedo was previously thought to be 0.4 (absorbing 60% of incoming light).

    Indeed. Thankfully, our civilization is molded more by the Greeks than the half-illiterate, murderous sheep-fucking savages who made up Middle Eastern Jewry and Christianity! Took a hell of a long time, but we're slowly climbing back out of that morass.

    Your God is a genocidal Bronze-Age holdover, Freeman. I don't know what angle I need to turn this at to get it through your head: he has exactly the same characteristics and temperament of the other God-figures in his milieu, and the theology evolved with the cultures it came in contact with over the centuries. Post-Exilic Judaism is a very different beast from its pre-Exilic form, for example. How much of this do you have even the slightest inkling of?

    Ah, you mean like with the Atomic Bomb? It sure is a good thing we've come so far as to be able to nearly totally annihilate an entire city with one bomb? Or it's so much better that we are more accepting of immoral behavior? Yes, we should be accepting of the Sinner. No, we shouldn't be accepting of the Sin.

      Atomic bombs ain't got nuttin' on the Great Flood, or that whole Apocalypse thing. Bzzzzt. Try again. Or don't; you're starting to make me embarrassed *for* you if this puerile horseshit is all you can muster.

      Is our immoral behavior worse than say the Galatians or Corinthians? I would suspect not. It just took us a while to catch up to them. Whether or not so doesn't make modern people any less redeemable.
