It’s curious that my wife’s campus had a major IT outage due to hardware failure, and within days the same thing happened at mine. Well, as they say, twice is coincidence, three times is enemy action.

I'm happy to report that "Scenario 2" won't be necessary, as NASA has just communicated to us that SciX funding will continue in 2026 (albeit at a reduced level). Therefore, we will not be forcing astronomers to leave ADS, but rather develop a plan that allows a longer transition.

Well this is worrying. NASA has maintained funding for ADS but not SciX (a broader database). In response, management is planning to *close* ADS in Feb 2026, forcing all users to switch to SciX. ☄️🔭 Funding info:

In the era of LLMs, what does learning look like? What happens when are overconfident in our understanding due to AI sycophancy? Is it even useful to use LLMs for education without outsourcing our thinking? New blog post:

This is an incredible image of comet 3I/ATLAS, taken by Satoru Murata ICQ Comet Observations group on 16 November 2025 from western New Mexico. Structure within the major dust tail from the comet is clearly visible, together with two smaller jets trailing the nucleus and maybe even an anti-tail.

Here are the

releases from varied NASA/ESA missions. Having worked with such telescope & spacecraft data for 40 years, my perspective is: no surprises. It's a comet; its differences from Solar System comets are intriguing but every comet is different!

A little less than a year ago, a large team of cosmologists reported evidence that dark energy (which drives the acceleration of the expansion of the Universe) evolves over time. This made a huge splash but has also been viewed with healthy skepticism. Today they report that evidence has weakened. 🧪

We watched Seven Days in May (1964), especially interesting after seeing A House of Dynamite (2025) last week. ( Also, I confess to being surprised that the 1964 film also features video calls between the President and the leading general. )
