Loeb’s 3I/ATLAS “Anomalies” Explained
Avi Loeb continues to claim that 3I/ATLAS has many anomalous behaviors that lead to the conclusion that it “might” be an alien spacecraft. He carefully hedges the probability that it is a spacecraft ...

Comet A6 Lemmon's closest approach to the Sun is on November 8th, 2025. I took this image on October 29th showing a huge increase in activity around the core. A very zoomed in shot using a 16 inch telescope f/18, 7400mm focal length with Canon R6.

Another tidbit in our new #Melissa story: the government shutdown means that federal researchers weren't gathering the usual science data during hurricane-hunter flights, because only mission-critical data were allowed. And those who did fly aren't getting paid. 🧪

At this point, publications that platform Loeb's comments, or feature him as the story lede (i.e., "Harvard Astronomer says....") deserve to be ridiculed and not taken seriously.
If you choose to look away from the hugely negative impact is having for the sake of clicks, then that's on you.

C/2025 A6 (Lemmon) from last night. It is a really good telescopic target right now! Lots more detail throughout the tail but especially close to the coma with streamers fanning out inside the dust tail. Interesting to see the turquoise coma breezing off to the right a bit too.
