Laser Ranging Makes GPS Satellites More Accurate

Although GNSS systems like GPS have made pin-pointing locations on Earth’s sphere-approximating surface significantly easier and more precise, it’s always possible to go a bit further. …

First Global Map Reveals the Deep Reach of Ocean Tides into Coastal Rivers

For centuries, the boundary between ocean and river has been conceptualized as a relatively static margin.

Measuring Earth's Wobble Without Looking at the Stars

Most people are familiar with the fact that the Earth spins on its axis once every day. The spin however, isn’t as steady as you might think. Like a spinning top slowing down, Earth’s axis wobbles, scribing out a circle on the night sky that currently points very close to the Pole Star in the northern hemisphere. This wobble is driven by the shape of the Earth and for decades, this wobble has been tracked by a network of radio telescopes. A team of astronomers have measured this wobble to a level of accuracy that has never been achieved before.
