"Saturn , Another Cosmic Sun
(I choose Topic 1, the reason is as follow)

One's banal speculation that whether the Saturn will transform into a sun-like planet is of no significance. Although it may happen 30 billion years later, it is thought to be a splendid subject study among the astronomical circle. Out of the research for the Saturn and its ring, they can deduce the fuzzy past of the solar system beings from the observable and predictable quantity as well as quality changes of the Saturn.

Recently?another gigantic and mysterious ring, which is also composed of dusty and ice, has been discovered by NASA’s JPL. The shape and dimension is so immense that it can contain about 10 billion earth-like bodies.
The significance of the discovery is not the catoptriclight it sends out, but the thermal radiation by which the NASA’s JPL found out, and behind the thermal radiation, which is more than 1.5 times it gains from the sun that matters. That shows that the Saturn is a humbler follower of the Jupiter , which boasts its inner energy, of which we could make use to confirm that the Saturn’s transformation may have come into being.

Cassini is the first to find the division of the saturnine ring by turning a telescope to the sky, and following him, Maxwell conducted theories to fulfill his demonstration that the ring of Saturn was a material system made up of innumerable moonlets ceaselessly whirling around it. Now it’s turn for JPL to find the inner energy of the Saturn."
