Open this photo up and look for the small, white dot just left of centre.
It looks like Venus, shining brightly in the twilight sky.
But it's us.
It's Earth.
From Mars.

This image from the Perseverance Mars rover came down yesterday.
The rover is looking down towards the ground, forlornly.
Wondering why someone would ever maroon it on that dead, cold planet.

Hey @nature.com, have you got an explanation for how the hell THIS happened? & especially why you accepted a paper with such a bizarre piece of genAI slop in it?!
& more to the point, why we should take you seriously at all going forward?

This is an incredible image of comet 3I/ATLAS, taken by Satoru Murata ICQ Comet Observations group on 16 November 2025 from western New Mexico.
Structure within the major dust tail from the comet is clearly visible, together with two smaller jets trailing the nucleus and maybe even an anti-tail.
