Life Expectancies of Stars
- Laboratories: star clusters
young: open clusters
old: globular clusters Omega Cen M13
Supernovae and Cosmology
- supernovae as standard candles
- SNIa light curve movie
- Supernova cosmology campaigns
- SN Ia digital discovery via subtraction
most distant examples
Our Milky Way Galaxy
Our Place in the Milky Way
- The naked eye Milky Way:
southern hemisphere, zoom to dark lanes - Galileo: telescope
- Immanuel Kant
- William Hershel's model (top view)
- Harlow Shapley globular cluster distribution: on the sky, top view in 3-D space
- interstellar dust
another example of scattering and absorption - simulated view of Milky Way seen from outside; a possible similar galaxy
Multiwavelength Milky Way: All-Sky Views
- optical: dust-obscured
- near infrared: stars, less dust
- radio at 21 cm: neutral hydrogen atoms
