  1. Stars are always out but they cannot be seen during the day. They can only been seen when the sun goes down.
  2. A constellation is a group of stars with a recognizable pattern.
  3. Some stars are brighter than others because of the amount of light produced and their distance
  4. The sun is the closest star to Earth.
  5. Her discovery helped astronomers measure space. Her work gave scientists a way to calculate distances to faraway stars and galaxies.
  6. Leavitt took a position as head of the photographic stellar photometry department.
  7. Henrietta Swan Leavitt is best known for her discovery of the relationship between per\iod and luminosity in Cepheid variables.
  8. At the beginning of the end of a star’s life its core runs out of hydrogen to convert to helium.
  9. In 1895 Leavitt became a volunteer assistant in the Harvard Observatory.
  10. There are an estimated septillion stars in our universe. This is a 1 followed by 24 zeros!
  11. A star is a luminous body of hot gas that generates energy through nuclear fusion.
  12. Stars form in molecular clouds. Molecular clouds range from 1,000 to 10 million times the mass of the sun and can span as much as hundreds of light years.
  13. Henrietta Swan Leavitt was an American astronomer, but she was not allowed to perform certain work because she was a female.
  14. Henrietta Swan Leavitt was an American astronomer, but she was not allowed to perform certain work because she was a female.
  15. She discovered 4 novas and around 2,400 variable stars.
  16. Free!
  17. After millions of years immense pressures and temperatures in the stars core squeeze the nuclei of hydrogen atoms together to form helium. This process is called nuclear fusion.
