WASHINGTON, D.C., June 2, 2015 -- Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled ...

Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy without a parent star, turning a once purely theoretical class of worlds into a ...

Measuring mass with marble fizz and massive bricks! Matter cannot be created nor destroyed. But weight, there’s more to know about the Conservation of Mass! STEM Challenge: Designing a Simple Balance ...

Swarm Flyby Gravimetry is a concept to determine the mass of asteroid or comets during flyby using a collection of small, disposable tracking targets called probes. The probes are deployed from a ...

Washington, DC - A group led by astronomers from Ohio State University and the Technion-Israel Institute of Technology have measured the mass of a unique black hole, and determined that it is the ...

An actively feeding black hole surrounds itself with a disk of hot gas and dust that flickers like a campfire. Astronomers have now found that monitoring changes in those flickers can reveal something ...
