In a historical milestone, astronomers using the NASA/ESA Hubble Space Telescope witnessed the catastrophic collisions in a nearby planetary system. As they observed the bright star Fomalhaut, scientists saw the impact of massive objects around the star.

The Sun's steady fusion output governs Earth's climate and underlies all biological and technological energy flows, from photosynthesis to fossil fuels.

In 2025, Europe celebrated the 30th anniversary of satellite navigation on the continent, a milestone built on decades of innovation, collaboration and excellence. Three decades of challenges and triumphs that have shaped the navigation systems we rely on today: EGNOS and Galileo, and that serve as legacy to building the satellite navigation systems of tomorrow.
