At the ragged frontier where the Sun’s influence gives way to interstellar space, Voyager 1 has stumbled into something that ...

Fresh mapping of the outer solar system has revealed a previously unseen pattern in the Kuiper Belt, the icy ring of debris beyond Neptune that has long been treated as a relatively simple torus of ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." Astronomers have discovered that the solar system may be ...

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

Having made its closest approach to the sun on Wednesday October 29, comet 3I/ATLAS will soon be visible from Earth again—before it leaves our solar system. While the comet—first spotted in July—has ...
