In India, the right to walk safely on designated footpaths is now a fundamental right. There’s lots we can learn from this. Here’s a super analysis from the BBC’s Soutik Biswas: www.bbc.com/news/article...

Supreme Court on walking: India is a nation of walkers - but its cities forgot them

India's top court has put the spotlight on unsafe footpaths and the country's forgotten pedestrians.

Another train travel thread. This time from Brussels to Lausanne. Track damage in the Netherlands was leading to delays so I got an earlier train than planned from Brussels in order to not miss my connection. The Eurostar app made rebooking extremely easy.

LISA Symposium Public Lecture ... Listening to the Dark Universe with Gravitational Waves and LISA ... by Lead NASA LISA Project Scientist from NASA’s Goddard Space Flight Center, Dr. Ira Thorpe. 6:30pm at Stamp Student Union Hoff Theater (Ground Floor) #lisasymposium2026 #lisamission #nasa #esa

Great talk from @saavikford.bsky.social about Astrophysics and EMRIs. What will we do if LISA sees 10,000 EMRIs? #LISASynposium2026 @lisacommunity.bsky.social

Great insight into the engineering of the LISA spacecraft this morning from ESA engineer Juan Pablo Rodríguez García. 🚀 #LISASymposium2026

16th International LISA Symposium June 21-26, 2026 Schedule: lisa-2026.astro.umd.edu/schedule.html Follow live: www.youtube.com/@LISAcommuni... #LISASymposium2026

The LISA spacecraft are much larger than I realised: 4.7m by 1.7m (3 adults width and 1 adult in height) #LISASymposium2026 @lisacommunity.bsky.social

Great to be at the 2026 LISA Symposium at The University of Maryland. Looking forward to a packed week about the incredible science and engineering of this exciting mission.

🎉 Today marks 10 years since the publication of the very first paper from LISA Pathfinder mission: "Sub-Femto-g Free Fall for Space-Based Gravitational Wave Observatories: LISA Pathfinder Results". A milestone that launched a decade of discovery and exploration beyond Earth.

@researchireland.ie is continuing a path laid down by the old (and old-fashioned) SFI in failing to work to build a national research ecosystem. Their strategy is something one might expect from a sectoral agency, not a national one. And that's been noticed www.irishtimes.com/ireland/educ...

Taken with our VLT over a period of four years, these images show the rotating disc of gas & dust around the young star AB Aurigae. Features like “twists” signal the places where #exoplanets could be forming 🪐 More: https://www.eso.org/public/videos/potw2622a/ 🔭 🧪 📹 ESO/A. Boccaletti et al.

Ireland's energy price hikes are a terrible symptom. If we want to stop them, we have to cure the disease.

We literally just posted about yesterday's solar records before seeing another has already been broken, with output reaching 1263MW (~25% of electricity demand at the time) just before noon. We'll have more on this but just a little reminder that you can follow these in real-time on our website.

Research Ireland, in partnership with the Embassy of France in Ireland, invites applications to the Ulysses 2027 Scheme. The deadline for applications is 28th May 2026, 16:00 local Irish time. Find out more and apply: https://pulse.ly/skwiuavydp

A postdoc in our group at the time, Gabriel Andres Piovano, applied for this in 2024 and we used the funds to support a visit of @chrislintott.bsky.social to give a public lecture at the @ria.ie about "Our Accidental Universe: Discoveries from Asteroids to Aliens"

Hello there! On this special occasion, we want to introduce a new kind of Force users in the galaxy: micro‑Newton thrusters.

Join Dublin City Council and Fingal County Council for a scenic, car-free 5km sunset cycle through the Phoenix Park. This family-friendly event is free to attend, but advance registration is required. Date: Wednesday, 13 May Register here: https://f.mtr.cool/gkdhzzhfqd

My paper computing gravitational wave energy fluxes for scattered orbits within the self-force approach has been published in Physical Review D: doi.org/10.1103/v6rz.... In the paper I make comparisons with the latest post-Minkowskian results, as well as post-Newtonian and numerical relativity.

I'm giving a public lecture Friday night (7pm Central, 17 April) for the Lake County Astronomical Society. If you'd like to join us, we'll be talking about how we gain knowledge about the distant universe -- see you there! Streaming link on YouTube is: www.youtube.com/@lakecountya...

The train from Arlanda to Stockholm has bar seating. Not quite sure why.

“In total, some 80GW of new clean renewable energy was added to the European grid last year — the peak equivalent of more than 50 nuclear plants” My take on a nuclear energy re-think is in the @irishexaminer.bsky.social www.irishexaminer.com/opinion/comm...

John Gibbons: I've changed my mind on nuclear power — we don't need it any more

Becoming energy independent is simpler than it's ever been — wind and solar have the potential to free us from endless energy shocks

After such an epic moonset, I was delighted to go home with just that but this day last year had another trick up its sleeve in the opposite direction. The horizon was all hazy, perfect to align the sunrise with North Bull Lighthouse.
