Turns out 3I/ATLAS change in gas composition is consistent with what we predicted a few months ago!
Our cosmic ray model does another great job!

Base-difference imagery of SDO AIA 211 Å shows the CME clearly associated with the recent X8.1+X1.5+X2.8 flare triad. Most of the material looks directed away from Earth, but we will see what coronagraph imagery and models have to say about it.

Some of Saturn’s moons sculpt its rings with gravity.
Here’s Prometheus (right) dragging ripples through the F ring as it passes.

Notre infographie sur la "marche du pingouin" ne vous a pas échappé.
Plusieurs nous ont répondu : "C'est un manchot!"
C'était un abus assumé. Mais voici une nouvelle infographie : comment distinguer un pingouin d'un manchot 👇
