Using the observations of the Solar and Heliospheric Observatory (SOHO) and Solar Dynamics Observatory (SDO), it may be possible to predict mass ejections from the Sun days in advance.

Indicate whether the statement is true or false

Question 2

How have Hubble images revised our view of the structure of planetary nebulae, and even the potential for the Sun to become one?

What will be an ideal response?

Answer to Question 1

TRUE

Answer to Question 2

Instead of just spherical shells, we know that many if not most planetary nebulae are bipolar ejections; often the appearance of a ring comes from the dual lobes coming directly at us and away from us. The intricate structure suggests that magnetic fields are molding the nebulae, and that perhaps the rotation and perturbation of a companion star may be often involved. It may be that only binary stars can produce these spectacular stellar shrouds.
