Every once in a while, the outer solar system reminds us that we've only discovered a negligible portion of it, and that the vast majority is still full of surprises. The latest example of this is a ...

HELSINKI — China has published coordinated papers outlining dual missions to the solar system’s edge, suggesting the long-studied project is nearing formal approval. A lead paper on the design and key ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

A new study with the incredibly exciting title of "Overdispersed Radio Source Counts and Excess Radio Dipole Detection" has announced quite a thrilling discovery, indeed: Our solar system is moving ...

"Our analysis shows that the solar system is moving more than three times faster than current models predict," says lead author Böhme. "This result clearly contradicts expectations based on standard ...
