'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 ...

Cosmic dust demystified

The solar system is a dusty environment, with trillions of cosmic dust particles left behind by comets and asteroids that orbit the sun. All this dust forms a relatively dense cloud through which the Earth travels, sweeping ...
