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 ...

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 ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

The object, estimated to be the size of a city block, is only the third known interstellar visitor to our solar system since scientists began keeping track of such things. The Hubble telescope ...
