Excellent news. Many congratulations to Prof. Dougherty. And many thanks to Martin Rees for his 30 years of service in the role.

Yes, on long timescales due to tides (bottom panel of figure) but on shorter timescales it speeds up and slows down all the time. Since the 1970s, it's gradually been speeding up a bit. It's a mix of weather, climate, tides, earthquakes, movements in the liquid outer core etc etc. All great stuff.

Anybody wondering about the reports that the day length has become a bit less than 24 hours could do worse than look at this figure I made last week for the Astronomy textbook I'm writing. Time is a lovely, but complicated, thing.

How and when to see July's full Moon and the Delta Aquariid meteor shower You might be lucky enough to catch a glimpse of Mercury as well as the Moon and Mars in the night sky this month.

BBC night sky pages so poor πŸ™„: "could also be possible to see parts of the Milky Way"; confusing discussion of perigee ("point in its orbit") and opposition; "probably need a telescope" = definitely; Moon/Mars evening not dawn; + usual meteors hype. Is "AI" to blame? www.bbc.co.uk/weather/arti...

Another day to remember that BBC Radio 4 weather summaries often say things like, "Today will be very hot and sunny. Farther north, it will be cooler, cloudy, and with some rain."
