(Image: The Wolf-Rayet star WR 124 in the constellation Sagittarius, imaged by the Hubble Space Telescope.) The prevailing theory of the formation of the solar system is that a large, nearby supernova ...

Astronomers know that our solar system formed about 5 billion years ago from material left over from previous generations of stars. However, beyond that, it gets a little murky. The prevailing theory ...

When most of us learn about the solar system, it seems like a pretty well-ordered place. Our Sun formed first, about five billion years ago, and the planets appeared a little later. As a very general ...

An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar ...

For several decades, scientists have debated whether the Solar System formed as a result of a shock wave from an exploding star -- a supernova -- that triggered the collapse of a dense, dusty gas ...

The origin of the differing tilts in the orbits of the planets in our solar system may have been revealed through the discovery of subtle warps spotted in many planet-forming disks around young stars.

Standard planet-formation models have been unable to reconstruct the distributions of the Solar System's small, rocky planets and asteroids in the same simulation. A new analysis suggests that it ...

The eyes of every astronomer widened this year when an interstellar traveler was discovered in our solar system.

And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.
