Alexis Rouillard (IRAP, Leibniz IAP) On Christmas Eve 2024, after seven Venus flybys to adjust its orbits closer to the Sun, the Parker Solar Probe reached its closest approach to the solar surface, at a distance of just under nine solar radii. The first seven years of this incredible mission have provided in situ measurements […]

Katarina Kraljic (ObAS) The strikingly anisotropic large-scale distribution of matter, the so-called cosmic web, is made of an extended network of voids delimited by sheets, themselves segmented by high-density filaments, within which matter flows towards compact nodes where they intersect. Do the properties of galaxies, such as their mass, star formation rate or morphology,  retain […]

Jean-Charles Cuillandre (CEA AIM, OSU Paris Saclay) ESA's Euclid journey from raw data to global awe began with its Early Release Observations (ERO) program, marking a series of pivotal media moments that showcased the mission's capabilities and long-term vision. In November 2023, the first release unveiled breathtaking color images from Euclid’s twin panoramic cameras, signaling […]

Rungployphan (Om) Kieokaew (IRAP) Cosmic plasmas drive dynamical processes throughout the universe, from magnetic field generation to explosive energy conversion. Magnetized plasmas in the solar system are the most accessible environments for in-situ measurements. Unlike theoretical or numerical simulation approaches, where assumptions about plasma behavior must be made a priori (i.e., on large, fluid-like, or […]
