Iron inside the Sun
Context
Scientists have discovered that iron inside the Sun is far more opaque (blocks more light) than previous models predicted. This was found through new experiments using advanced technolog
Key Findings
- Iron in the Sun absorbs more energy (is more opaque) — up to 30% to 400% more than expected, depending on the type of radiation hitting it.
- The new measurements were done by recreating Sun-like conditions in a lab using X-rays, iron samples, and ultrafast detectors.
- These findings show that our theoretical models are underestimating iron's opacity, which means they may be miscalculating how energy moves through the Sun.
- This solves an old puzzle: earlier, scientists noticed a mismatch between models and actual solar data (like sound waves inside the Sun), but couldn’t explain it. This new research explains the mismatch.
