Earth has recorded its shortest day since records began in the 1960s.
On the 29th of June 2022, the National Physical Laboratory in England recorded the shortest day in history at 1.59 milliseconds less than 24 hours.
Meaning the Earth rotated on its axis in less than 24 hours. This has happened around 28 times since the 1960s.
Scientists don’t know exactly why this is happening but there are some possible explanations.
The Earth’s axis is tilted but there is a slight wobble, a bit like you might see with a spinning top.
Things can affect this wobble including the Moon which stabilises the Earth and Ocean tides,
Astronomers Leonid Zotov, Christian Bizouard, and Nikolay Sidorenkov believe it is such a wobble that is causing the rotation to speed up.
