Using Galaxy Clusters to Look Into the Past

The video discusses the use of X-rays in astronomy to study distant galaxies through gravitational lensing, focusing on high mass X-ray binaries (HMXBs) and their impact on galaxy formation and ionization. It also covers NASA's ICON mission, which aims to study the Earth's ionosphere and its interactions with solar winds and weather, using the innovative Pegasus XL launch process.

What role does the ionosphere play in satellite communications, according to the text?

How do extreme weather events on Earth affect the ionosphere?

Describe the launch procedure of the Pegasus XL rocket as mentioned in the text.
