2026 MIST Council Election Results

It is our pleasure to announce the results of the latest MIST Council Election.

  • Samuel Wharton (University of Leicester) is elected for a 3 year term as a MIST Councillor
  • Jewel Abbey Relampagos (Lancaster University) is elected for a 1 year term as the MIST Student Representative

In addition, due to concerns from the community regarding the ongoing UKRI/STFC funding situation, MIST Council have also decided to charter Mark Lester (University of Leicester) as an additional councillor to inform and steer the council in matters related to this specific brief, as set out in Article 4.5 of the MIST Charter.

We would like to congratulate everyone on their new roles. The full composition of Council can be found on the MIST website (https://www.mist.ac.uk/community/mist-council). We would like to thank all the candidates for putting themselves forward and everyone who took part in the voting. We received votes from 132 people which represents a turnout of 21.5% of people registered to receive the MIST emailing list.

Finally, MIST Council would like to extend their thanks and gratitude to our outgoing members: Fiona Ball and Georgios Nicolaou. We would also like to say a special thank you to Andy Smith who was co-opted to be on MIST council while Rosie Johnson was on maternity leave, thank you for all of your hard work.

Statement from MIST Council regarding the STFC Funding Situation

Statement from MIST Council regarding the STFC Funding Situation

MIST Council is deeply concerned by the ongoing STFC funding uncertainty and its impact on our community and beyond.

The current combination of prospective delayed and reduced funding, together with already volatile financial situations at universities across the UK, is placing significant strain on research groups. In some cases, institutions may be unable to support researchers through gaps between projects, increasing precarity across the community and adding significant pressure on early-career researchers.

We are concerned that continued uncertainty risks accelerating a brain drain from the UK, as skilled researchers reconsider their future in a system offering limited stability. The loss of expertise at any career stage would have lasting consequences for UK space science.

 

What is going on?

For those that are unaware of the situation, it is complex and evolving. We suggest the following sources to get up to speed on the current developments.

What are we doing about it?

Behind the scenes, MIST Council is actively engaging with relevant parties to understand the scale of the challenge and to identify constructive ways forward.

  • We are seeking seasoned members of the community to join MIST Council on a task force to help develop options and represent the needs of our community. If you would like to be involved, please reach out to us via the MIST Council email (This email address is being protected from spambots. You need JavaScript enabled to view it.) by the end of this week (13th February 2026).
  • In addition to the task force, we want to provide an open forum for discussion and collective input among all members of the wider MIST community. We are exploring options and will be in touch as soon as possible with further details.
  • We believe in working together in the face of the current challenges and we are collaborating with UKSP and others to strive for a fair and positive outcome for all. We are reaching out to members of the SSAP (Solar System Advisory Panel) to explore the hosting of a community town hall meeting, like the one already being organised by the AAP (Astronomy Advisory Panel), to provide an open forum for discussion and collective input.

 

What can you do to help?

There are several open letters representing people in various career stages that have been made available to sign. We encourage you to read the relevant letter(s) and to sign them if you support them:

The Royal Astronomical Society are also urging Fellows to lobby their MPs against the cuts, and have included a template letter that can be used to do so:

MIST Council will continue to advocate for transparency, stability, and funding structures that recognise both the long-term nature of our science and the people who deliver it.
We thank you for your continued support in this period of uncertainty.

The closest-to-the-Sun-ever direct observation of a shock wave and its heliospheric journey

By Domenico Trotta (Imperial College London)

Shock waves, i.e., abrupt transitions between supersonic and subsonic flows, are present in a large variety of astrophysical systems, and are pivotal for efficient energy conversion and particle acceleration in our universe [1]. Despite decades of research, the mechanisms by which particles are accelerated at shocks are a matter of debate, and are crucial to several applications, ranging from explaining acceleration of cosmic rays to the highest energies [2] to the study of space weather phenomena [3].
Shocks in the heliosphere are unique, being directly accessible by spacecraft exploration, thus providing the missing link to the remote observations of astrophysical systems. Interplanetary (IP) shocks are generated because of solar activity phenomena, such as Coronal Mass Ejections (CMEs), and play an important role in the energetics of the heliosphere where they propagate [4].
The ground-breaking NASA Parker Solar Probe (PSP, [5]) and ESA Solar Orbiter [6] missions are probing the previously unexplored inner heliosphere, providing datasets with unprecedented resolutions.
We used such novel observational window to report direct PSP observations of a CME-driven shock as close to the Sun as 0.07 A, making it the closest to the Sun direct observation of a shock wave to date. The shock then reached Solar Orbiter at 0.7 AU, enabling us to study the evolution of the shock throughout its propagation in the heliosphere.
We characterized the shock and its environment. At PSP, we found a sharp shock with moderate strength, and investigated how switchbacks, fundamental constituents of the near-Sun environment, are processed by the shock crossing. In contrast, the Solar Orbiter observations revealed a very structured shock transition, with shock-accelerated protons with energies of up to 2 MeV. The differences between the two shocks are due to both evolution effects and the large-scale geometry of the event, crossed by the spacecraft in two points only. This study elucidates how the local features of IP shocks and their environments can be very different as they propagate through the heliosphere.

Top: Spacecraft configuration at 17:30 of Sep. 05, 2022 (immediately after the IP shock crossed PSP). In this plot, the Sun is at the center, the Earth is represented by the green circle, and the dashed (solid) lines indicate the spacecraft radial (along a Parker Spiral with a nominal speed of 400 km/s) connection. Bottom: Magnetic field magnitude, its components in the RTN system, ion bulk flow speed, density and temperature as measured by PSP (left) and later by SolO (right). The plots show an overview of the event (a,c) with a zoom around the shock transition at both spacecraft. The dashed magenta line marks the shock transition, and the blue shaded area in panel (b) indicates the approximate end of the CME sheath as observed by PSP.
