By monitoring auroral activity on exoplanets, we may be able to infer the presence of water on or within an exoplanet.
Stars don't sit still, they twinkle
We live inside the atmosphere of an active star.
When we look up at night and view the stars, everything we see is shinning because of distant nuclear fusion.
When discs form around stars, there is interaction of angular momentum between disc, planets and parent star, and this interaction affects the rotation of the parent star, and that will affect the lithium abundance.
Deep beneath the surface of the Sun, enormous forces were gathering. At any moment, the energies of a million hydrogen bombs might burst forth in the awesome explosion.... Climbing at millions of miles per hour, an invisible fireball many times the size of Earth would leap from the Sun and head out across space.
Our planet doesn't seem to be the result of anything very special.
But the day is spent; And stars are kindling in the firmament, To us how silent--though like ours, perchance, Busy and full of life and circumstance.
