ELI5: Explain Like I'm 5

Julius Scheiner

Julius Scheiner was a man who liked to study stars and light that comes from beyond the Earth. He was very curious about how things work and he wanted to know more about the universe.

So, Julius used something called a spectroscope to help him study these stars and light. A spectroscope is like a special tool that helps you see what colors are inside light.

Julius was very good at using this tool and he made many important discoveries. One of his biggest discoveries was that there were things in space that were too far away for people to see with just their eyes.

This was a very big deal because it meant that there was a whole universe out there that people didn't even know about before!

Thanks to Julius's work, we now know much more about the stars and the universe. He was a very important scientist who helped us see the world in a new way.
