What a fun, creative paper! And useful to the study of nearby galaxies too.

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

A very nice result by my friend Tom Bakx and colleagues, confirming the surprisingly warm dust at z=8, at 91 K. Also he was interviewed in this morning's BBC Radio 4 Today programme 😄 apparently right after Michael Gove

there's a moment in PARADISE LOST where Satan arrives in Eden and realizes Hell isn't a place; it's a thing he carries within him and it'll follow him wherever he goes. and i think about that when i see these awful rich men whose monstrous wealth has enriched them not at all

Many other @ec-euclid.bsky.social papers being released this week, including by Daniela Vergani and team on discoveries of galaxies with unusual emission lines - here's an explainer by @stephenserjeant.bsky.social 🧪🔭
!["Euclid's ability to cover such a large area of sky makes it a marvellous place to find rare objects that often could not be discovered in any other way. Euclid also doesn't just take images; its spectroscopic instrument also splits light up like a rainbow to diagnose how redshifted (how far away) each galaxy is and the conditions inside each galaxy. In this paper [Vergani et al] we used Euclid's spectroscopic instrument to unveil a population of rare galaxies with stronger ionizing radiation inside them, perhaps caused by a curious, unusual history of star formation that's assembling the stellar masses of galaxies. Unpicking this will be the subject of a lot of future research, and this is just the tip of the iceberg of the rare object discoveries awaiting us with Euclid."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:rqzhexkrr5iazknlluqozsw7/bafkreibxkye62qpn3cwcxxt4z2bk6eq3c5aui4qyw3pz3xckbwunzmmuxq@jpeg)

This is yet another example of how you beat the far right. By beating them, not trying to be them. By having your own agenda, not aping theirs. With courage and conviction - and humour - not fear and timidity.
