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 ...

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 ...

We’ve all seen this happen in a science-fiction movie: our plucky heroes jump into their ramshackle spaceship and escape the bad guys by flying through the treacherous asteroid belt, where huge rocks ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

Our solar system’s latest and only third known interstellar visitor is becoming more fascinating by the week. Spotted in early July, the object, dubbed 3I/ATLAS, is widely believed to be a comet. It’s ...

When Terrence Dwyer received a knock on his door and a flyer for a solar panel system small enough to fit on his deck, he was quickly sold. Solar systems that plug into regular wall outlets have been ...
