We can't visit, but new imaging systems like LUVOIR may give us information on what is happening there with a decent amount of detail. https://en.wikipedia.org

  Also the ELT (claimed to be operational starting in 2025) [1] will already allow study of the atmospheric composition of extrasolar planets (I guess that means spectroscopy). [1] https://en.wikipedia.org/wiki/Extremely_Large_Telescope https://en.wikipedia.org/wiki/Extremely_Large_Telescope

  LUVOIR can provide up to about 25 km imaging resolution in visible light at Jupiter The planet is ~10,000 times further away. Back of envelope puts the resolution at 250,000km. The earth is 12,000km in diameter. At 5.8x Earth mass and assuming similar density it would be a bit more than twice as wide and 25,000km diameter is easy to work with giving the planet a width of 1/10th of a "pixel". That's not nothing. In fact it's quite a lot relative to nothing. But it's still a long way from a well resolved image.

    Edit Oops. Forgot to apply the inverse square law. 10,000x further means resolving features of 10^10 greater area.
