A tracking device that fits on the head of a pin

(PhysOrg.com) -- Optical gyroscopes, also known as rotation sensors, are widely used as a navigational tool in vehicles from ships to airplanes, measuring the rotation rates of a vehicle on three axes to evaluate its exact ...

NASA uses Earth as laboratory to study distant worlds

The study of exoplanets—planets that lie outside our solar system—could help scientists answer big questions about our place in the universe, and whether life exists beyond Earth. But, these distant worlds are extremely ...

Soap bubbles for predicting cyclone intensity?

Could soap bubbles be used to predict the strength of hurricanes and typhoons? However unexpected it may sound, this question prompted physicists at the Laboratoire Ondes et Matière d'Aquitaine (CNRS, France) to perform ...

'Going deep' to measure Earth's rotational effects

Researchers in Italy hope to measure Earth's rotation using a laser-based gyroscope housed deep underground, with enough experimental precision to reveal measurable effects of Einstein's general theory of relativity. The ...

Researchers clarify dynamics of black hole rotational energy

Astrophysicists at MIPT have developed a model for testing a hypothesis about supermassive black holes at the centers of galaxies. The new model enables scientists to predict how much rotational energy a black hole loses ...

Stars' clockwork motion captured in nearby galaxy

(Phys.org) —Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars.
