「 By combining the imaging power of lots of smaller telescopes scattered across a plateau, ALMA is able to spot regional differences in the presence of specific elements in Io's atmosphere, as well as identify different isotopes of those elements 」
[#ActuScience@IRAP ] A young IRAP PhD student formulates a new #theoretical model of the giant #magnetospheres of the planets #Jupiter and #Saturn: "By considering only the global motion of the #plasma (coming from the moons #Io and #Enceladus), it is possible to understand it simply as... a competition between various rotation resistances!"
While I'm writing, I'm currently thinking about consent and power imbalances.
Take Io and Argus, the Greek legend has Zeus and Io as lovers. But in what way did Io consent to the consequences of being turned into a cow or having to face Hera's wrath because Zeus couldn't keep it in his pants?
Like given his power Io couldn't say no really. Gods tend to be nasty if you say no.
In what way did she consent to imprisonment and 24 hour a day surveillance?
