Researchers have laid out a new, comprehensive theory for how the solar system formed — inside the bubble of a long-dead, giant star.

According to a new study, a low-mass supernova roughly 12 times heavier than our sun may have triggered a gravitational collapse that eventually created our solar system.

How Did the Solar System Form? The tale of our sun may begin with another star: a predecessor whose fiery death brought about the birth of our solar system.

Scientists with the University of Chicago have laid out a comprehensive theory for how our solar system could have formed in the wind-blown bubbles around a giant, long-dead star.

– Gavriel, age 10, Paducah, Kentucky A cloud of collapsing gas created our Sun, the first thing to form in our solar system. This happened about 4½ billion years ago.

NASA's spacecraft Lucy has already started its four-billion-mile odyssey to the "fossils" of the solar system, looking to solve the mysteries of our cosmic home ...

A new view of the solar system's early days proposes that the first two kinds of solid materials — the precursors of space rocks and ultimately planets — both formed at the same time.

Scientists are looking at a new way moons in the early solar system could have formed – from giant rings surrounding their planet. Even Earth and tiny Pluto could have harbored a ring at one point.
