20 million years to become a star: Cosmic clock unlocks mystery of sun’s birth time

SMRTR summary

Scientists have discovered that our sun took approximately 10 to 20 million years to form. Using a complex process called bound-state beta decay of thallium-205, researchers measured nuclear transition strength and decay rates. This breakthrough required collaboration from over 50 scientists across 37 institutions in 12 countries. The study provides insights into the early solar system and star formation processes. The findings align with previous estimates and may lead to further discoveries in atomic physics and stellar evolution.
