Byzantine solar eclipse records illuminate obscure history of Earth's rotation

To improve understanding of variation of Earth's rotation in the 4th--7th centuries CE, a research team analyzed Byzantine records from this period to identify total solar eclipses around the Eastern Mediterranean. Five total eclipses with reliable information on location, timing, and totality were identified, in 346, 418, 484, 601, and 693 CE.

The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5
