Sun's Energy Source
The Sun shines through nuclear fusion. Its core fuses hydrogen atoms into helium, releasing vast energy amounts, equivalent to millions of nuclear bombs per second.
Core's Extreme Conditions
For nuclear fusion to occur, the Sun's core reaches temperatures over 15 million degrees Celsius and experiences intense gravitational pressure, making fusion possible.
Energy Transfer Process
Produced energy takes thousands of years to reach the Sun's surface. It transitions from the radiative zone to the convective zone, where it finally ascends.
Sunlight's Ancient Journey
Despite taking centuries to surface, sunlight takes just 8 minutes and 20 seconds to travel the 93 million miles to Earth after emission.
Helioseismology Insights
Helioseismology, the study of sunquakes, reveals the Sun's interior structure. Scientists observe wave patterns on the surface to understand the unseen core's dynamics.
Sun's Magnetic Field
The Sun's magnetic field is generated by its rotating, convecting plasma. This field extends beyond Pluto, influencing space weather and forming the heliosphere.
Sunshine's Elemental Role
Sunlight is essential for life, driving photosynthesis on Earth. It's also responsible for weather patterns and climate, making Earth habitable.Sun's Heartbeat
The Sun's core rotates faster than its surface, completing a full rotation every 7 days, unlike the surface which takes about 25 days.
