Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift ...

Neutrinos are tiny particles that barely interact with anything. Trillions of them pass through your body every second, yet you’ll never notice. They have no electric charge and barely any mass. Still ...

Neutrino mass measurement techniques represent a cornerstone of modern particle physics and cosmology. Given the elusive nature of neutrinos, experimental approaches have evolved to measure their ...

In billions of years’ time, after our sun has burned through all of its fuel and puffed up to be a red giant, it will eventually shrink and cool until all that remains is the dense core of the former ...

Situated roughly 10,000 light-years from Earth, the planet lacks a parent star and instead drifts solo through space.

In a milestone that could impact the future of physics, researchers have managed to place an upper mass limit on the subatomic particle called the neutrino. Without knowledge of the mass possessed by ...

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators recently measured the masses of several key nuclei with high-precision by ...

This graphic shows how microlensing was used to measure the mass of a white dwarf star. The dwarf, called LAWD 37, is a burned-out star in the center of this Hubble Space Telescope image. Credits: ...
