How we study the universe when we can't reach it
In short: Humanity can reach the Moon and the edge of our solar system, but the rest of the universe remains physically inaccessible. This video explains the methods astronomers use to study distant galaxies and celestial bodies that are far beyond our reach.
Because the distances in space are so vast, physical exploration is impossible for the majority of the universe. Instead, astronomers rely on advanced technology to gather information from the stars beyond our own galaxy.
The presentation explores the techniques used to observe deep space, highlighting how we translate light and data into a map of the cosmos. It matters because it reveals the ingenuity required to understand a universe that we can see but never touch.
