It feels like the title should be “uninhabited”. Life on earth doesn’t survive because we continue to be bombarded with nutrient carrying asteroids, it just needed them to kick it off. That few nutrients are likely to make it from the surface to the ocean means the genesis is unlikely to occur, but it doesn’t seem to make a decision about whether an unlikely genesis could survive, even if only in a small pocket of the ocean.
Starlink is causing problems, but it seems to me that this image was made in bad faith to oversell the case. The caption says it’s a combination of 29 separate exposures, but if those exposures were combined properly, you wouldn’t see the satellites (median combination does wonders, and there are more sophisticated techniques which do even better). Some streaks start at one chip edge and extend to another chip edge, without continuity across the focal plane. So it’s not at all clear just how this image was created. And why on earth is it not flat-fielded? Maybe this is just really sloppy image processing, but even amateurs can do far better than this, leaving the final combination with no satellites at all.
On Dec. 30, 2023, Juno came within about 930 miles (1,500 kilometers) of the surface of the solar system's most volcanic world. It made a second ultra-close flyby of Io just this week.

It’s impressive how much detail Juno was able to capture even on the night side. What I love about Io is how it’s instantly recognizable. Nothing even remotely resembles it in the solar system.
Cue the flat-earthers who are going to jump on this while completely ignoring all other aspects including the gravity required to make this happen, and somehow claim this is scientific proof that they were right.
