SUMMARY

The discussion centers on the distances from the core of the Sun to its atmospheric layers, specifically the photosphere and chromosphere. According to NASA's resources, the photosphere begins approximately 400 kilometers (about 248 miles) from the core, while the chromosphere starts just above the photosphere. Additionally, participants express frustration over the use of miles as a measurement unit. The pressure levels of the chromosphere and photosphere were also queried but not answered in the discussion.

PREREQUISITES
  • Understanding of solar structure and layers
  • Familiarity with astronomical measurements
  • Basic knowledge of atmospheric pressure concepts
  • Access to NASA's solar research resources
NEXT STEPS
  • Research solar atmospheric layers using NASA's IRIS mission resources
  • Explore the pressure measurements of the Sun's chromosphere and photosphere
  • Learn about the significance of the photosphere in solar phenomena
  • Investigate the differences between miles and kilometers in scientific contexts
USEFUL FOR

Astronomy enthusiasts, educators, students studying solar physics, and anyone interested in the structure of the Sun's atmosphere.

Simple question, how far from the core does each layer of the sun's atmosphere start? I couldn't find enough information in google.

It's in miles, but it's NASA stuff. Cheers :)

Ugh... Miles... Why do they still use miles? Anyway, thanks!

Does anyone know what the pressure of the chromosphere and the photosphere is?
