Why Do We Need To Know About Lunar Eclipse
Learning about lunar eclipses helps us see why space scientists, called astronomers, find them exciting. These scientists study space and learn about distant planets by watching how they move in front of stars, blocking some of their light, which looks a bit like an eclipse from far away.
This technique has helped find more than 2000 planets, and some of these could even have life, like the planet Kepler 62F. So, understanding eclipses is not just cool, but it’s also key to finding new worlds and maybe even life outside our planet.
