MOSCOW, Idaho — Sept. 3, 2025 — A team led by the Southwest Research Institute and including University of Idaho’s Matthew Hedman, a professor of physics, discovered a new moon orbiting Uranus. The ...

A pattern in the movements of a brown dwarf that orbits a Sun-like star is likely to be caused by a moon. If confirmed, this would be the first exomoon, that is a moon orbiting a planet that in turn ...

This back-and-forth motion is because the orbit of our quasi-moon is not the same as ours but is disturbed by the gravitational pull of the Sun, and by the gravitational pull of the other planets.

For researchers at the University of Idaho, spotting a moon 6 miles wide orbiting Uranus, a staggering 1.8 billion miles from Earth, may actually be easier than finding a white cat in a snowstorm. A ...
