Margaretha Kirch (born around 1703, died after 1744) was an important German astronomer. She came from a family of scientists and made her own discoveries. Margaretha is best known for her work at the Berlin Observatory. She helped observe the stars and planets. She also discovered a famous comet.

Early Life and Learning

Margaretha Kirch was born into a family of astronomers. Her parents were Gottfried Kirch and Maria Margaretha Kirch. They were both well-known astronomers. Margaretha also had a brother, Christfried Kirch, and a sister, Christine Kirch.

Margaretha's father passed away when she was only seven years old. From about age 10, she and her sister Christine learned astronomy. They worked as assistants to their parents. Later, they helped their brother Christfried with his observations. Margaretha never married. She spent her life studying the sky. She kept a special diary to record her observations of the weather and stars.

Working at the Berlin Observatory

In 1716, Margaretha's brother, Christfried, got a job. He became an astronomer at the Academy of Sciences in Berlin. This meant he also worked at the Berlin Observatory. Margaretha, her mother, and her sister joined him there.

Margaretha and Christine worked as assistants. They helped with important tasks. They made many observations of the stars and planets. They also did calculations to predict where planets would be. This was called making "planetary ephemeris."

Discovering a Comet

Margaretha Kirch made a big discovery on January 3, 1744. She found the Great Comet C / 1743 X1. This was a very exciting moment! She used two different telescopes to watch it. One was 2 feet long, and the other was 6 feet long. She carefully recorded her daily observations. She kept track of the comet in her watch book until February 25, 1744.

After the comet passed the sun, Margaretha saw something amazing. On March 5, she observed and drew the comet's tail splitting. It looked like streaks! Other famous astronomers saw this too. They observed the same splitting tail a few days later. Her observation from March 7 is even shown in an old drawing.

Even with all her hard work and discoveries, Margaretha Kirch never got official recognition. This was also true for her mother and sister. They were all talented scientists.
