The New Space Weather Mission

The video discusses the European Space Agency's (ESA) plan to launch a satellite to predict solar weather, providing a 5-day warning for solar flares and coronal mass ejections (CMEs). This satellite will be placed at the L5 Lagrange point, allowing it to monitor sunspots before they face Earth. The video also covers a study on galaxy death, revealing that ram pressure stripping by intergalactic plasma is a major cause. This process strips gas from galaxies, preventing star formation and leading to their early demise. The study suggests this phenomenon occurs both in and outside galaxy clusters.

How do astronomers determine why some galaxies die early?
