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

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 used the sharp vision of NASA’s Hubble Space Telescope to repeat a century-old test of Einstein’s general theory of relativity. The Hubble team measured the mass of a white dwarf, the ...

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 ...

Using a state-of-the-art device for measuring mass, researchers have made their most precise determination yet of Planck's constant, an important value in science that will help to redefine the ...
