3I/ATLAS has now made its closest approach to the sun and Earth and is now heading back out toward the outer solar system. On ...

SPACE (KXAN) — A star flying through the night sky may be the fastest-moving solar system in our galaxy. Possibly a planet a little larger than Neptune orbiting a small star, the system could be ...

Interstellar comet 3I/ATLAS makes its closest approach to Earth on Dec. 19. Here's how you can track its progress both during ...

Scientists tracked interstellar comet 3I/ATLAS and found rotating jets in a rare sun-facing tail during its 2025 pass through ...

I/ATLAS has passed its closest point to Earth, meaning we will soon lose sight of it for good. Some scientists want to send a spacecraft to chase down the alien comet — or the next interstellar object ...

While the Voyager spacecraft are constantly traveling out of the Solar System, sometimes they are getting closer to Earth.

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 ...

The cosmological principle predicts uniformity, and the CMB dipole reflects our 370 km/s motion that radio counts should ...

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 ...
