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 ...

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

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 ...

DURHAM, N.C. -- One of the tiniest building blocks of the universe has a weigh-in problem, and Ashutosh Kotwal is determined to get to the bottom of it. For nearly 30 years, the Duke physicist has led ...

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: ...

This article provides a comprehensive method for utilizing a thermogravimetric analyzer to measure mass loss in alumina, including specific considerations for precise and consistent results. Precisely ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets ...
