sorry if the question has already been posted,
What are those that look like lakes filled with? and does Loki contain magma or a liquid? Daniel |

According to previous temperature measurements, the greater part of the surfaces around Loki, while definitely warmed by internal heat, were far too cool to be liquid.
In fact, coincidentally, they are roughly comfortable for human presence! https://www.sci.news/astronomy/map-loki-pat...n-io-04854.html So that would be compatible with a solid surface that is glassy. On the other hand, Io brings uncertainty across time and fine scales of space, so maybe what we're seeing now is different. |

Yes, wonderful images. It's interesting that the northernmost patera of Mazda Catena, the site of a strong specular reflection here, was very likely also the location of a specular reflection seen by Voyager 1 45 years ago here. The temporary brightening was interpreted at the time as a blueish cloud emitted by the patera, but it's more likely that it was a specular glint, that was strongest at the time when the blue filter image was taken.
The most striking thing about the Loki specular reflection is how uniform it is- that's telling us something interesting about the resurfacing process. John |
