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.

Saturn's Weather‐Driven Aurorae Modulate Oscillations in the Magnetic Field and Radio Emissions

By Nahid Chowdhury (University of Leicester)

Planetary parameters at Saturn have exhibited mysterious time variabilities and periodicities for almost two decades. After the first Voyager measurements of the 1980s led to a determination of a rotation rate for the ringed planet, the advent of the Cassini mission in the 2000s showed that the measured length of a day at Saturn was subject to change. Numerous theories were proposed to explain the time variabilities seen in planetary parameters ranging from the radio emission through to the energies of neutral atoms and these fell into one of two general categories. The first was that a driving mechanism for the observed periodic behaviour would be situated externally to the planet, within the magnetosphere. The second was that a driving mechanism would be situated within the planet’s atmosphere.

Using infrared observations of Saturn’s northern polar auroral H3+ emission taken with Keck-NIRSPEC in 2017, we investigated ion flows in our search for a signature of the twin-vortex mechanism in the planet’s upper atmosphere that was purported to drive the observed periodicities. H3+ is an ion found in the ionosphere of gas giant planets and measurements of its line-of-sight velocity are indicative of the more general motion of constituents in the planet’s atmosphere.

By grouping our spectral data into quadrants of local northern planetary magnetic phase, we set up our experiment to probe the ion flows driven by the planetary period current. This led to the astonishing detection of the proposed ionospheric twin-vortices that are considered to be responsible for the periodicities witnessed throughout Saturn’s planetary and magnetospheric environments. Our observations show that local atmospheric weather effects at Saturn drive the twin-vortex flows while also generating some auroral emissions. This result has far-reaching implications for both other planets in our Solar System and exoplanetary systems.

 

Figure caption: Shown here is an example of the type of winds within the upper atmosphere that are driving the ionosphere to move in the way observed in this new paper. This set of two vortices rotate around the pole of the planet, driving currents within the ionosphere, which then reach out into the surrounding magnetosphere, producing the bright aurora and magnetic field changes observed by Cassini. This weather system was originally proposed by Chris Smith in a paper in Monthly Notices of the Royal Astronomical Society in 2011 (doi:10.1111/j.1365-2966.2010.17602.x) – and it is these modelled flows that we show here.
