Text, MYTH versus REALITY
Myth side
Text, We can study other galaxies by visiting them.
Reality side
Text, Other galaxies are too far away to visit. Even if you could travel at the speed of light, it would take millions to billions of years to reach most other galaxies. The closest galaxies to our own Milky Way are dwarf galaxies thousands of light-years away. We study other galaxies from afar, using powerful space telescopes like Hubble, Chandra,  and Webb.
