In July 2025, astronomers spotted a strange object from deep space that is now flying through our solar system. Called ...

Updated predictions for 3I/ATLAS’s perijove with Jupiter on March 16, 2026, reflect revised non-gravitational acceleration ...

NASA’s JPL Horizons updates for 3I/ATLAS revise the non-gravitational acceleration model, affecting its projected perijove ...

I/ATLAS's unexpected acceleration is likely caused by mass loss and outgassing as it passes close to the sun, not advanced ...

Within the diameter of Jupiter’s orbit around the Sun, the coincidence between the perijove distance and the Hill radius has a statistical likelihood smaller than 0.00004. In case the ...

When theoretical physicist Dr. Michio Kaku made a public appearance in late October and told the world to 'watch for it' in a ...

On October 30, 2025, the radial acceleration component A1—normalized at a heliocentric distance of 1 au—was listed as 1.6×10⁻⁶ ...

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...
