A recent groundbreaking study published in Geophysical Research Letters has revealed an astonishing new insight: Earth’s rotational axis has shifted 31.5 inches in less than two decades, largely due ...

The Earth wobbles. Like a spinning top touched in mid-spin, its rotational axis fluctuates in relation to space. This is partly caused by gravitation from the sun and the moon. At the same time, the ...

Let's review a bit of physics in preparation for Part 2 of our technology transfer series on page 28. All elements in a rotating body have a measure of kinetic energy. Simply stated, this is "energy ...

Because of Earth’s dynamic climate, winds and atmospheric pressure systems experience constant change. These fluctuations may affect how our planet rotates on its axis, according to NASA-funded ...

The Earth in orbit around the Sun, with its rotational axis shown. Earth's axial tilt does not change appreciably in direction or magnitude over the course of a day or even a year, which is why the ...

Scientists have just plotted changes in Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. Previously, scientists were only able to track ...
