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 ...

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 ...

What is mass? It seems like a synonym for weight, but that isn’t quite right. Weight is how we measure the pressure that gravity exerts upon things. But mass? Mass is the actual presence of an item — ...

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, 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 ...

A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time 3 minutes Despite keeping us ...

The ALICE experiment of the Large Hadron Collider has, for the first time, directly measured a phenomenon known as the "deadcone," which has allowed physicists to directly measure the mass of a ...

The measure of a black hole is what it does with its stars. That’s one lesson astronomers are taking from the first-ever picture of a black hole, released on April 10 by an international telescope ...
