Cosmic Journeys: Rivers of Energy Inside the Sun

NASA's Solar Dynamics Observatory provides insights into the sun's energy and activity. The sun, a plasma-filled nuclear furnace, exhibits phenomena like loops, flares, and coronal mass ejections. Plasma dynamics in the sun's core and outer layers generate magnetism, influencing solar activity. Magnetic fields can lead to powerful eruptions, impacting the solar system.

What does the Solar Dynamics Observatory help us observe on the sun?

• The sun's gravitational pull

• The sun's distance from Earth

• The sun's core temperature

• The sun's fiery loops and flares

What is the temperature of the sun's core?

• 20 million degrees Celsius

• 15 million degrees Celsius

• 10 million degrees Celsius

• 5 million degrees Celsius

How long can the journey of plasma from the sun's core last?

• Tens of millions of years

• A few years

• A few months

• A few days

What forms near the sun's equator due to its rapid rotation?

• Calm seas

• Frozen zones

• Vast rolling waves

• Static fields

What is produced by the churning motions of plasma?

• Magnetism

• Electricity

• Heat

• Light

What can happen if the energy in the sun's magnetic fields is strong enough?

• They can cool down

• They can twist and snap

• They can disappear

• They can become visible

What is a potential result of a coronal mass ejection?

• A decrease in solar temperature

• A billion tons of plasma being ejected

• A stable magnetic field

• A reduction in solar flares
