Paul-Auguste-Ernest Laugier facts for kids
Paul-Auguste-Ernest Laugier (born December 22, 1812, in Paris – died April 5, 1872) was a French astronomer. He was one of two famous French astronomers known as M. Laugier.
Early Life and Learning
Ernest Laugier was the son of André Laugier, a chemist. Ernest studied astronomy under a well-known scientist named François Arago.
Amazing Discoveries
After his studies, Ernest Laugier started working at the Paris observatory. He made many important discoveries! He studied things like magnetism, comets, and solar eclipses. He also looked at meteors and sunspots. Sunspots are darker, cooler areas on the Sun's surface.
Laugier also helped make astronomical clocks better. These clocks are very precise and important for observing the sky.
Mapping the Stars
In 1853, Laugier figured out the exact location (latitude) of the Paris observatory. He corrected some old mistakes, making the observatory's measurements even more accurate.
He also created a list of 53 nebulae. Nebulae are giant clouds of dust and gas in space. Later, in 1857, he published another list. This one showed the positions (declination) of 140 stars.
Laugier wrote many articles about astronomy for a publication called Connaissance du Temps. He also worked for a long time with François Arago. They researched how Earth's physics work. For several years, Ernest Laugier was the president of the Academy of Sciences.
