NASA | STEREO reveals the Entire Sun

The video discusses the Stereo spacecraft's mission to observe the sun from different angles, providing a complete view of the sun for the first time. It highlights the importance of understanding solar activity, such as coronal mass ejections and solar flares, which can disrupt technology on Earth. The video explains how Stereo and other satellites help predict space weather by observing sunspots and active regions. This knowledge is crucial for preparing for solar storms and protecting technological systems. The video also outlines the future of solar observations and their potential benefits.

What is the primary mission of the Stereo spacecraft?

• To explore the outer planets

• To provide a full view of the sun

• To monitor Earth's weather

• To study the moon's surface

Why is it important to monitor solar activities like coronal mass ejections?

• They can enhance satellite communications

• They can improve weather forecasts

• They can increase solar energy production

• They can disrupt navigation systems and electrical grids

How did scientists initially get a sense of the sun's far side before the Stereo mission?

• With ground-based telescopes

• By sending probes to the sun

• Through the Michelson Doppler Imager on Soho

• Using the Hubble Space Telescope

What is the expected duration of the unprecedented view provided by the Stereo spacecraft?

• At least 2 years

• At least 5 years

• At least 10 years

• At least 8 years

What will the Stereo spacecraft help scientists understand better?

• The composition of asteroids

• The geology of Mars

• The dynamics of our star, the sun
