First Ever Direct Measurement of Earth's Rotation
Description: New research is plotting changes in the Earth's axis through laboratory measurements. Researchers constructed the world's most stable ring laser in an underground lab and used it to determine changes in Earth's rotation. Previously, scientists were only able to track shifts in the polar axis indirectly by monitoring fixed objects in space. Capturing the tilt of Earth's axis and its rotational velocity is crucial for the accurate functioning of modern navigation systems. [Source: ScienceDaily]
