a NEW PAPER led the incomparable Dr. Elizabeth Iles (accepted by PASA) quantifies how astronomers might be biased in how they judge galactic bars

Turns out that male astronomers are consistently more optimistic than their peers when it comes to measuring length

arxiv.org/abs/2511.09908

A stellar density map of a barred spiral galaxy viewed face-on. The image shows a dark background with a central bright, elongated feature (the bar) surrounded by fainter spiral arms. The color bar on the right indicates the log10 Stellar Density in units of solar mass per square parsec, ranging from 0 (black/dark) to 4 (white/bright). The x and y axes are labeled in kpc (kiloparsecs), spanning from -10 to 10. Overlaid on the image are several highlighted regions: a central white, bright feature is enclosed by a dashed cyan ellipse representing the full Bar region. A smaller, cyan dashed box labeled Inner-bar is located along the bar's major axis, excluding the ends. Two symmetrically placed, dashed teal boxes labeled Bar-ends are located near the extremities of the bar. This visualization highlights the key components of the galaxy's bar structure.

The perils of using a community kiln! Somebody else's pot exploded and took a chunk of my Green Man with it.

Far right protest today:
29 - police officers injured
9 - protestors arrested

Proscribed group protests:
0 - police officers injured
1,600 - protestors arrested

We have Keir Starmer and Yvette Cooper to thank for this absurd anomaly

The sophisticated COLIBRE simulations finally land on the arXiv: arxiv.org/abs/2508.21126. Treating these with sonification, we can get new intuition for galaxy evolution to augment our visuals. Sound on for the explainer vid, visit the site for more! colibre.strw.leidenuniv.nl/videos.html 🔭🧪

Hollowing out the sculpture and sticking it back together.

#pottery #ceramics #sculpture #pottersofbluesky
The back of a partially hollowed out portrait bust. Thehollowed-out portrait bust from underneath. The edge of the cut-out section is scored and painted with slip (liquid clay) to enable the bust to be reassembled. The bust is reassembled, ready for the join to be smoothed over.

Today, I cut off the back of her head and scooped out her brains.
Life-size clay bust of a woman's head. The clay is still soft, and the back of her head has been sliced off so that the bust can be hollowed out. The clay bust from behind, with the region to be removed marked out. Some of the clay has been removed to reveal the newspaper-stuffed bag where her brain would be. The newspaper 'brain' is removed.

A strange thing happened in the kiln today. I don't know why the engobe on the bottom of the mug behaved like this. A friend had a pot with the same engobe in the same kiln, and it came out completely normal 🤷‍♀️

Just got warned that the new "Voice Isolation" feature in Teams, if turned on and trained on a male voice, will filter out all the women in the room, while still allowing the men in the room to be heard online.
