The interplanetary comet 3I/ATLAS is remarkably rich in a specific type of water that contains deuterium, meaning it came ...

Comet 3I/ATLAS, an object from another star that was found speeding through our solar system last summer, is now fading from ...

Our solar system may not be as isolated as we once thought. According to a new study, more than 1 million interstellar objects could be lurking in the outer reaches of our cosmic neighborhood, quietly ...

New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices in ...

The eROSITA spacecraft has built the most precise map of soft X-rays over Earth, observing a fascinating phenomenon driven by ...

For decades, the four known forces of nature, gravity, electromagnetism, and the strong and weak nuclear forces, have ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course. When ...

NASA physicist Slava Turyshev has proposed that a hidden 'fifth force' may exist in the solar system, masked by environmental effects. The theory could explain why cosmic-scale observations deviate ...
