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).

    Once again calling for a new mod for "fairy-tale-based argument".

    Since that's a bit long, how about the "-1 Trumping" ?

    I was originally conscientiously pointing out that your statement didn't apply to Christians. You don't want to talk about religion. That's just fine. Then stop deriding the people who believe in it. All manner of inappropriate tags can be placed on quite a few topics. In reality the entire string of comments along with half of your post was off-topic in relation to the original article.

      > pointing out that your statement didn't apply to Christians

      Tell that to a lot of "Christians" who have a very different opinion than you.
      I've talked to enough Evangelists to respectfully disagree.

      But hey, the Universe IS full of wonderful things.
