What is the Pickering Fleming system?
…to be known as the Pickering-Fleming system, she studied the tens of thousands of celestial photographs taken for the Draper Memorial—a project dedicated to the amateur astronomer Henry Draper of New York. In the course of her work she discovered 10 novae, 52 nebulae, and hundreds of variable stars.
Why was Annie Jump Cannon deaf?
Cannon was a child she had a cold. The cold caused Ms. Cannon to become deaf. Every year she could hear less and less until she couldn t hear anymore.
What did Annie Jump Cannon do for the HR diagram?
Hertzsprung Russell Diagram It plots a star’s luminosity against its surface temperature. Stars are grouped into spectral types which can be viewed as either temperature or color groupings that were created by Annie Jump Cannon in the 1890’s.
What did the Harvard computers do?
The Harvard Computers was a team of women working as skilled workers to process astronomical data at the Harvard Observatory in Cambridge, Massachusetts, United States. “The women were challenged to make sense of these patterns by devising a scheme for sorting the stars into categories.
How did the Harvard computers help advance our knowledge of stars?
Cannon’s Harvard Classification Scheme is the basis of the today’s familiar O B A F G K M system. She also categorized the variable stars into tables so they could be identified and compared more easily. These systems connect the color of stars to their temperature.
Who Mapped the universe?
Not long after, in 1924, Edwin Hubble was able to clearly resolve individual stars in other galaxies, and so was able to determine the distances to these “island universes” — paving the way for future astronomers who would map the universe.
