Find out how Hubble almost accidentally recorded the breakup of comet C/2025 K1 (ATLAS) immediately after its passage by the Sun. We explain what astronomers discovered about the fragments, the comet’s unusual composition, and why this observation could be important for future missions and the understanding of the early Solar System.
Find out why Europe is investing in the Sterna constellation and how the 20 satellites being built by OHB Sweden could improve weather forecasting from the Arctic to the Mediterranean. We bring an overview of the roles of ESA, EUMETSAT and new microwave measurements in the earlier detection of dangerous weather phenomena.
Find out why the European Space Agency is seeking new missions for video monitoring of Earth from very low orbit and what such technology could bring to the monitoring of floods, fires, the environment, and agriculture. We bring an overview of the call's objectives, technical challenges, costs, and possible applications by 2030.
Find out why the European Space Agency’s Hera mission matters for the future of planetary defense. We bring an overview of the journey toward the Didymos system, the consequences of the impact of NASA’s DART probe, and the questions to which Europe should soon provide the first concrete answers.
Find out why ESA’s Plato has entered the final phase of testing in a space simulator and what this European mission could discover about Earth-like planets. We bring an overview of the key tests, the operation of 26 cameras, the planned launch on an Ariane 6 rocket and the mission’s scientific goals.
Find out how ESA’s CryoSat, known for monitoring polar ice, managed after a software upgrade to record a geomagnetic storm caused by a powerful solar flare in January 2026. We bring an overview of the mission, the role of the magnetometer, and the significance of these data for science and space weather monitoring.
