The main text says that organics are a proposed interpretation, not that there is direct evidence for them. Interesting article but is the headline misleading?

The curve shows when the different colored area moves past the side facing the earth. The light curve shows the rotational period.

What am I missing?If it indeed counteracted the earlier spin, imagine how fast Haumea was spinning before. Or perhaps the spot is simply indicative of deeper layers, if Haumea fragmented on the original impact. (On the side facing away from the impact and remodeled after.) That's putting spin on things.

An impact with a smaller Kuiper belt object could explain the organic-rich spot. It would also explain the crystalline water ice, which requires relatively warm temperatures to form and turns back into amorphous water ice pretty quickly. I agree with bsercombe.

Hence the fast spin. Bet it's an impact crater. Hence the fast spin.
