NASA picture of the day today is a real 🏴󠁧󠁢󠁳󠁣󠁴󠁿beauty! This is a composite image of the ~5000yo Callanish Stones on the Isle of Lewis. The amazing Giuseppe Petricca has only gone and photographed the Sun at noon there, every few days, for a whole year. #Dedication 🔭🧪👌 ℹ️: science.nasa.gov/image-articl...
The imposing Callanish Stones stand talk with their shadows spanning out across the glass.  It's a super clear sky, but looks cold. Above the central stone is a strange figure-of-8 shape of dots.  This is the location of the Sun, at noon, on various different days across the year.

Neptune's moon system is bizarre. JWST data helps explain why
Neptune's strange moon and ring system has puzzled astronomers for decades, but data from the James Webb Space Telescope (JWST) might help explain how it formed.

I work a bit on landslides. We often think of landslides in terms of human costs: roads, infrastructure, lives. But to lose a species? A sobering read. www.theguardian.com/world/2026/j...

Today was a weird day. I woke dreaming I was promoted (there was a rollercoaster ride, which is both an accurate analogy and also should be real), farewelled my 94 yo grandmother and gave the eulogy.

I was thinking about an old friend this morning. How we’d hit the bar at Newcastle airport on work trips. Found out at lunch he’d passed. Watch out when people fall off the radar. The little world of Australian engineering geophysics lost a mentor and a friend. RIP Mick.

Just back from a geochemistry conference in Prague, having visited the Terezin concentration camp on a spare day. Amongst the incarcerated (which included Dvorak’s protege and a heartbreaking number of kids), I found a fellow earth scientist, who somehow survived the killings.

We're gonna need the Solar System ephemeris models updated on a regular basis! Really hoping we have better constraints on the masses and distances of KBOs so these models account for this in more detail.

A new episode of Strombolian activity occurred on 24 March 2025 at the Southeast Crater of #Etna. It started on the morning and culminated around noon, and then diminished; some explosive activity was still going on at nightfall. Seen from Nicolosi, on the south flank of the volcano

A Sequoia (Californian redwood) I randomly encountered in the Blue Mountains. It’s still dominated by some nearby red gums, and probably planted in the 1800s. Made me think of the flammable blue gums in California in the recent fires, both results of the first botanical exchange in 55Myr.

I have now posted my provisional analysis of fatal landslides in 2024 on my blog. In total, 708 fatal landslides (excluding those triggered by an earthquake), cost 4,492 lives. This is far higher than in any previous year for which I have data. eos.org/thelandslide.... Published under a CC license.
A map showing the distribution of fatal landslides in 2024. There are two clusters in South Asia, plus others in SE Asia, East Asia, East Africa, SE Brazil, the northwest of South America and in Central America.  Author's own data, published under a CC license. If you want a higher resolution version, please contact the author.The cumulative total number of fatal landslides in 2024 compared with previous years.
