When the JWST came to life and began observations, one of its first jobs was to gaze back in time at the early Universe. The Assembly of Galaxies is one of the space telescope's four main science themes, and when it observed the Universe's first galaxies, it uncovered a mystery. According to our understanding of how galaxies evolve, some were far more massive than they should be.
Did you spot the spider in this morning’s post? Here’s the original photo:

Reader Enrico sent me a link to this video called “Blind Spot“, a 2024 movie that’s 95 minutes long. The topic is antisemitism on American college campuses.
The YouTube notes:
“Blind Spot” is the only current film focused exclusively on campus antisemitism. Featuring never-before-seen interviews with students before and after October 7th, along with testimony before Congress and insights from officials, journalists, and university staff, it reveals how antisemitism on campus didn’t appear overnight—and what can be done about it. Described as “like nothing I’ve ever seen” and “a fire alarm ringing,” the film highlights the resilience of Jewish students and the urgent need for change.
It begins with the infamous conflict between Rep. Elise Stefanik and the Presidents of Harvard, Penn, and MIT. The Presidents’ answers about the rules were correct, but the Presidents of Penn and Harvard later resigned, largely because of the hypocrisy of their answers: free speech is indeed within the colleges’ ambit, but they enforced it erratically and hypocritically.
The rest of the video consists of short interviews and statements and scenes of anti-Israel demonstrations from many schools, including the University of Chicago. As we already know, anti-Semitism is pervasive at many of these schools. What impresses me is the resilience and determination of the Jewish students. Compared to the angry, shouty, ace-covered advocates of Palestine, they seem eminently rational. I found it both depressing and heartening.
This film was made last year, but I can’t say things have gotten palpably better in the last year. As Hamas continues to lose in Gaza, the intensity of Jew hatred has only grown.
BTW, my Belgian colleague Maarten Boudry, a philosopher with whom I’ve published (and an atheist), just published an article in Quillette detailing his impressions of his first trip to Israel.
We have only one set of Readers’ Wildlife left, so I’m putting in a “Spot the. . .” feature from Neil Taylor of Cambridge in the UK. But please send in your photos, folks.
Neil says this:
The first photo is a tree stump draped in spider webs in which a spider is hiding. . . .I’m not a spider expert but I think it is a running crab spider (Philodromus sp.). Quite a beautiful little thing.Can you spot it? I’ll post the reveal at 11 a.m. Chicago time. I think this is of medium difficulty. Please do not reveal in the comments where it is; let others have the fun of finding it.
NASA’s Perseverance Rover didn't just look up—it captured a sprint across the Martian sky! On March 1st, its navigation camera locked onto Deimos as the moon raced overhead in the pre-dawn darkness. Sixteen rapid-fire, 3-second exposures stacked together reveal the moon's movement across the Martian sky. The pictures were taken in very low light, so it's pretty grainy and noisy, but there are two additional stars in the sky, Regulus and Algieba, in the constellation Leo.
Scientists have discovered that black holes don't just devour everything—they also fire back. While nothing can escape the event horizon, black holes generate ferocious winds that blast outward at significant fractions of the speed of light. New research challenges the long-held belief that they flow smoothly and continuously. Instead, these winds are violent, fragmented bursts resembling rapid-fire streams of gas bullets. Astronomers have now witnessed this phenomenon firsthand, detecting five distinct gas components travelling 20-30% the speed of light and erupting like geysers from the black hole's vicinity.

For years the galactic center was thought to be too chaotic and hostile for planet formation. This is wrong. New ALMA observations have seen planet nurseries flourishing in the turbulent Central Molecular Zone near our Galaxy's heart, challenging everything we thought we knew about how worlds are born. Planets find a way.
