Stellar Astronomy and Women's Contributions

The video discusses the significant contributions of women in stellar astronomy, focusing on Annie Jump Cannon's star classification system and Cecilia Payne-Gaposchkin's discovery of star composition. It highlights the role of the Harvard Computers, a group of women who made foundational contributions to the field, and emphasizes the lasting impact of their work on modern astronomy.

What field of astronomy has a strong tradition of women making significant contributions?

• Cosmology

• Planetary astronomy

• Stellar astronomy

• Galactic astronomy

Why did the focus of astronomy shift from stars to galaxies about a hundred years ago?

• Because stars were too far away to study

• Due to the invention of new telescopes

• Due to the discovery of the expanding universe

• Because galaxies were easier to observe

What was one of the main tasks women were hired to do in stellar astronomy?

• Studying black holes

• Classifying stars

• Designing telescopes

• Mapping galaxies

Who developed a star classification system that is still used today?

• Maria Mitchell

• Annie Jump Cannon

• Henrietta Swan Leavitt

• Cecilia Payne-Gaposchkin

What did Cecilia Payne-Gaposchkin discover about the composition of stars?

• They are made mostly of carbon and oxygen

• They are made mostly of hydrogen and helium

• They are made mostly of iron and nickel

• They are made mostly of silicon and magnesium

What percentage of stars is composed of hydrogen, according to Cecilia Payne-Gaposchkin's discovery?

• 50%

• 60%

• 75%

• 90%

What was the initial reaction to Cecilia Payne-Gaposchkin's discovery about stars?

• It was immediately accepted

• It was celebrated worldwide

• It was met with skepticism

• It was ignored

What fundamental assumption about the universe is based on Payne-Gaposchkin's discovery?

• The universe is mostly made of galaxies

• The universe is mostly made of stars

• The universe is mostly made of hydrogen and helium

• The universe is mostly made of dark matter
