*Hastily converts all my #comet activity modelling code to output in Olympic swimming pools per day rather than SI units* 😅

Some cool new pictures and interesting preliminary findings about 3I/Atlas from the JUICE flyby last November.

The article also features my processing of the NavCam image sequence :)

☄️ #Comet C/2026 A1 (MAPS): Will We Witness the Easter Comet?

This Saturday, Comet C/2026 A1 will pass dangerously close to the Sun. Will the icy nucleus survive and transform into the brightest spectacle in the Easter sky?

Researchers explain why this journey is considered suicidal, how to locate the comet using Venus, and where to follow the events live from space via satellite.

Just how insanely precise was the #3iAtlas correction engine burn?

The margin is absurdly tight.
Jupiter's Hill radius on that date is 53.502 million km. The margin is 0.06 million km, that's one part in 1,000 relative to the Hill radius, and one part in 26,000 relative to Jupiter's full orbital diameter.
That's 57,000 km of margin on a 53.5 million km target, after travelling from interstellar space.

The non-gravitational acceleration measured at perihelion is what brought the trajectory to that value. Without it, 3I would have missed the Hill sphere entirely.

So the perihelion burn didn't just slow the object down.
💥It course-corrected with enough precision to thread a 0.1% margin on Jupiter's gravitational capture boundary💥

After a journey of billions of years across interstellar space.

That's not a snowball melting unevenly.
