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).

    I don't know why you're making such a big deal about all that - it's obvious if you just stop to give it a moment's consideration:

    God moves in mysterious ways.

    There's banter back and forth between God and Job in the book of Job. In that dialogue God tells Job that He is smarter and knows more than Job. So, for us, God does move in mysterious ways at times.

      Okay, but Donald Trump ALSO says he's smarter than us...

        Donald Trump isn't stupid. You may very well disagree with everything he has to say, but he isn't stupid. Personally, I don't like him and disagree with quite a number of things he says. The alternative was Clinton, though. Even then, I would have preferred Clinton over Obama. The one thing Obama and Trump have in common is Charisma. Hitler had plenty of that, too. Charisma just blinds people to the crazyness that comes out of their mouths.

    God moves in mysterious ways.

    They've literally had millennia to collect and refine the book of comebacks, what do you think they teach in Seminary school anyway?
