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.

What is the primary purpose of the ESA's planned satellite?

• To explore the surface of the Sun

• To predict solar weather and provide early warnings

• To study the Earth's atmosphere

• To monitor the Moon's surface

What is a coronal mass ejection (CME)?

• A type of galaxy

• A type of solar flare

• A satellite orbiting the Earth

• A wave of highly magnetic plasma from the Sun

What happens to a galaxy when it is considered 'dead'?

• It merges with another galaxy

• It stops producing new stars

• It becomes a black hole

• It explodes

What is ram pressure stripping?

• A process where galaxies are pulled into black holes

• A technique for launching satellites

• A process where intergalactic plasma strips away a galaxy's gas

• A method of measuring galaxy mass

Where does ram pressure stripping occur according to recent studies?

• Only near black holes

• Only in isolated galaxies

• Only in large galaxy clusters

• In both large clusters and smaller galaxy groups
