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

Kinda surprised nobody’s snapped this up. Usually it goes in under a day. Would anyone like it? 🔭🧪
Would anyone like my @royalastrosoc.bsky.social 2026 diary? I use an electronic calendar so this is surplus to requirements. 🧪🔭

Met my first moon landing conspiracy theorist on holiday at dinner a couple of days ago. Luckily awkwardness avoided when I said "oh you're one of those people that believe in the Moon?" 🔭🧪

Thinking only of Rosalind Franklin today, and what was stolen from her (and so many other female scientists alongside her).
Rosalind Franklin and the damage of gender harassment
Spurred by a recent report on sexual harassment in academia, our columnist revisits a historical case and reflects on what has changed—and what hasn’t

Reminded today that I picked an image of an amazing, late scientist deeply involved in the discovery of the structure of DNA and so much more, whose name should be known by everyone, for my postgrad stats and deconvolution lecture 🧪 github.com/stephenserje...

I helped make a film, out this week, called “Rovina’s Choice,” about the deaths this man without conscience or accountability has caused — already 600,000, ⅔ of them children.

Genuinely delighted to have contributed to the Physics Without Frontiers workshop on AI for Afghan Students - rather nice write-up here (the pic of me also shows the work of my excellent postdoc Dr Laura Hunt) 🧪🔭 www.ictp.it/news/2025/11...

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)

Looking forward to learning all about how the right should move left to win elections tomorrow. They should maybe dye their hair pink, learn to love pronouns.

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.

I just love this surrealistic illustration of the cosmic optical background that Guy Bilout did a few years ago for a NYT article. Light comes from the dark Universe.
