✨ #EPSC2027 will be in Toulouse, France from 19-24 September 2027.

🪐 #EPSCDPS2025 press release: A swarm of spherical rovers, blown by the wind like tumbleweeds, could enable large-scale and low-cost exploration of the martian surface bit.ly/epscdps_tumblerover

✨ News from #EPSCDPS2025: JWST Reveals Dark Beads and Lopsided Star Patterns in Saturn’s Atmosphere, in a new study by @northumbriauni.bsky.social: bit.ly/epscdps_jwstsaturn

James Webb Space Telescope reveals dark beads and lopsided star patterns in Saturn's atmosphere A study of Saturn's atmospheric structure using data from the James Webb Space Telescope (JWST) has revealed complex and mysterious features unseen before on any planet in our Solar System.

🪐 BREAKTHROUGH: Researchers have discovered mysterious dark beads in Saturn's atmosphere using the James Webb Space Telescope. Professor Tom Stallard and an international team have revealed complex structures in Saturn's sub-auroral ionosphere never seen before.

Presented at #EPSCDPS2025 in Finland! 🚀

“The low-friction and viscous detachments drive deformation on Mars”.
Our study shows how weak detachments shape tectonic deformation in the Tharsis region, offering new insights into Martian lithosphere dynamics.

A lot of people crowding around pancakes (crepes) being served

The grand finale! 😁
#pancakes #EPSCDPS2025

phew, almost made it to the end of #EPSCDPS2025. Not gonna lie, I think we're all flagging here towards the end 😅
Looking forward to the pancakes(!) at the farewell event and then crashing. #EPSCDPS

It's the last day of #EPSCDPS2025! We hope everyone had a great time! We have one more talk today @ 3pm:

Nader Haghighipour will present "Effects of secular resonances on the dynamical evolution and orbital architecture of planetary systems in binary stars" in room Neptune.
Abst:

Photo of a conference room with the speaker at the podium on the right and a slide projected on a screen on the left. The slide caption reads: "Thank you! Kiitos!" ("Thank you" in Finnish, where the conference is taking place). On the right is a multicoloured meteor with a smiley face, on the left text reading: "Currently looking for a job!" The image has been slightly edited to remove contact information.

Adding to the collection of job-searching slides :D

Cole Gregg explores whether interstellar material might come from circumstellar debris disks (it probably can!), and if so, where that material might come from and what would be the physical characteristics thereof #epscdps #epscdps2025

John Forbes: according to a model based on stellar populations, our galaxy contains a tapestry of streams of interstellar objects (ISOs) as illustrated in this still from a video that has been shown repeatedly in this ISO session #epscdps #epscdps2025

Not sure how many in #planetaryscience are here:

Riccardo Pozzobon tragically passed away in Alaska.

#EPSCDPS2025 : Interesting talks by Xuan Li (collaboration with Richard Chatterjee) on revising cosmic shoreline to incorporate molecular weight, and by Erik Meier Valdes on what has been learned so far from the Hot Rocks survey. (Most interesting is that LHS1478b has a tentative hint

Yukun Huang derived explicit expressions for the drift and diffusion coefficients of the normalized orbital energy of gravitational scattering of planetesimals by a planet. These equations are analytically derived, universal, and eco-friendly. #EPSCDPS2025

Close encounters of the average kind: Yukon Huang explores an analytic model of interstellar objects are scattered out of their planetary systems #epscdps #epscdps2025

Rosemary Dorsey - giving a thesis talk on predictions of the ISO (interstellar object) yield with Rubin Observatory - Most of the results presented are in this nice paper iopscience.iop.org/article/10.3... #EPSCDPS2025

At #EPSCDPS2025 I've met @plutokiller.com, who discovered Eris and proposed Planet Nine! I've already interacted with him for my book about missing planets, but it has been a pleasure to meet him by person!

Have interstellar objects ever hit Earth? No confirmed instances based on fireball statistics but intriguing hints. Dusan Marčeta explores the possibilities with a simulation and it could happen! #epscdps #epscdps2025

#EPSCDPS2025 : Now at the Cosmic Shoreline session, co-chaired by Jake Taylor (Oxford Glasstone fellow) and Richard Chatterjee (Oxford PCDgroup doctoral student finishing soon #proudadvisor ) . This session deals with the question of when a planet can retain an atmosphere.

Rosemary Dorsey reviews a simulation of the interstellar objects that NSF-DOE Rubin Observatory might reveal - how many, what their characteristics may be (maybe 6-51 objects - hard to detect!) @vrubinobs.bsky.social #epscdps #epscdps2025

A composite phase function for cometary dust comae Comets represent the most preserved planetesimals we can nowadays study and dust is one of their major components. Once emitted in the coma, cometary …

Ivano Bertini presents a new phase curve for cometary dust comae - paper at www.sciencedirect.com/science/arti... (under a pay wall so you'll need institute access) #EPSCDPS2025

#EPSCDPS2025 Soon the second GEOASTRONOMY session will be starting. In this session, among other interesting talks, Oxford PCDgroup postdoc Claire Guimond will talk about the expectation of ubiquitous CO2 sources on rocky planets. I will give my talk on subNeptunes as rockyworlds,

ExoClock ExoClock is a project to monitor the ephemerides of transiting exoplanets. Everyone with a telescope and a CCD camera can participate!

Hearing about the very cool Exoclock project, which has more than 10000 amateur observations of transiting exoplanets - hugely important to keeping track of our known planet population: www.exoclock.space #EPSCDPS2025
