Galaxies have an overall internal motion called disk velocity. It’s how gas, dust, and stars move around the galactic center.

Newfound interstellar object 3I/ATLAS may be carrying pristine material from early in the Milky Way’s star-forming history.

NASA has discovered a new interstellar comet that's currently located about 420 million miles away from Earth. The space ...

Dubbed 3I/ATLAS, the comet poses no danger to Earth and will remain roughly 150 million miles away as it speeds by.

NASA said the comet will make its closest approach to the sun in late October, scooting between the orbits of Mars and Earth ...
