The correct answer is: Gravity. Stellar winds in low- to intermediate-mass stars tend to be driven by the stellar magnetic fields; in massive stars by outward pressure from the stars’ own radiation. Check the entry about Stellar Wind #HubbleWordBank https://t.co/iOXppJfID2
#QuizTime If you read our 📖 #HubbleWordBank entry about Stellar Wind, answer this: Which factor does NOT drive stellar winds?
1/ Hubble’s imagery captured the effects of stellar wind, as seen in the Veil Nebula. Astronomers suspect that before the Veil Nebula’s source star exploded it had a strong stellar wind. Learn more about Stellar Winds from our 📖 #HubbleWordBank: 🔗 https://t.co/iOXppJfID2
1/ What are Stellar Winds? Let's ask our 📖 #HubbleWordBank!
Stellar winds are fast-flowing streams of particles that are emitted from a star.

巨星 AG Carinae，是我们银河系中最亮的恒星之一。
它的周围环绕着不断膨胀的气体和尘埃“壳”，整个星云宽度大约有五光年。

1/ What is a Star? Let's ask our 📖 #HubbleWordBank! A star is an approximately spherical body of plasma, which is held together by its own gravity and prevented from collapsing by the energy generated inside it by the fusion of hydrogen into helium. 🔗 https://t.co/EuI7A9rVEj
