The SERPENTINE project is coming to an end in the end of June, 2024. The project has been extremely successful, providing new knowledge on its science questions and delivering tools, catalogues and datasets to its user communities. The project organised…
In Finland every 8th and 9th grade student at the upper comprehensive school does from one to two weeks of work life orientation training called TET. In fall 2023 University of Helsinki Space Physics team hosted two TET trainees. Aaro…
Solar eruptions hurl gigantic magnetized plasma clouds into interplanetary space and accelerate charged particles to relativistic energies. Their consequences at Earth are estimated using the modeling of the solar atmosphere and heliosphere. The first step in a successful space weather…
Solar energetic electron (SEE) events are strong enhancements of high-energy electrons associated with solar flares and coronal mass ejections (CMEs). These particles have speeds that are a large fraction of the speed of light, and we can measure them with…
Shock waves and turbulence are ubiquitous in our Universe, where they play a fundamental role in explaining many observed phenomena. In particular, the complex, often spectacular interaction between shocks and plasma turbulence is a very promising pathway leading to the…
An exhaustive multi-spacecraft analysis of the 17 April 2021 event revealed that multiple distinct SEP injections at the Sun played a major role in creating the wide longitudinal spread of solar energetic particles (SEPs) in the inner heliosphere. This points…
In research, usually every scientist is doing their own thing when it comes to data analysis. Most people rely on their own tools, written in their favourite programming language, or on some software they have been provided within their closed…
Solar eruptions are able to drive shock waves in the heliosphere. We call these shock waves Interplanetary (IP) shocks. IP shocks are ubiquitous in the heliosphere, and the possibility to observe them in-situ is crucial to address important aspects of…
