A team of MIT researchers has described a new method for finding the mass of exoplanets by studying the spectra of light passing through the planet's atmosphere. Because a planet's mass can tell us a ...

Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science fiction. Measuring the mass of such a small planet based ...

In science, there are thousands of ways to measure the world around us that the average person may never encounter. For example: Pascals to measure pressure, Candles to measure light intensity, and ...

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 ...

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 ...

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 ...

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 ...
