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 ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." When you purchase through links on our site, we may earn ...

Long before humans walked the Earth, your solar system had a brush with two blazing blue stars that passed surprisingly close ...

Discovery: On July 2, 2025, astronomers confirmed Comet 3I/ATLAS, marking only the third interstellar object (ISO) ever detected passing through our Solar System, after 1I/ʻOumuamua (2017) and ...

NASA is tracking a mysterious, fast-moving object entering our solar system, raising questions about whether it's just a comet — or possibly something more advanced. The object, known as 3I-ATLAS, was ...

There’s a bit of a paradox about our galaxy: it’s both jam-packed with stars and cavernously empty. The Milky Way is crowded in the sense that it holds hundreds of billions of stars, as well as ...

The universe is supposed to look the same no matter where you stand. That idea, known as the cosmological principle, sits at the heart of modern astrophysics. It says matter spreads out evenly when ...

How fast and in what direction the solar system moves is a critical cosmology test. New research offers answers that challenge the standard model. (Nanowerk News) How fast and in which direction is ...
