Researchers from the International Earth Rotation Service, which is based in Paris, recorded the shortest day in the history of our planet.
As scientists found out, a full rotation around its axis took 1.59 milliseconds less than usual for the third planet from the Sun.
It is generally believed that a day on Earth lasts 24 hours, but since the 1970s its rotation has been slowing down, so 27 leap seconds are needed to maintain the accuracy of time, reports Daily Mail.
So, in 2016, on New Year’s Eve, the world clock stopped for a second. Then in 2020, the day on the planet shortened by 1.47 milliseconds, and on July 29, 2022, it took 1.59 milliseconds, which is a new record for Earth. Usually people do not notice such changes, but this fact has an impact on satellites and navigation systems.
Meanwhile, domestic scientists believe that this may be the “Chandler oscillation” – a change in the rotation of the Earth around its axis, writes the publication “Profile”.
– The normal oscillation amplitude is about four meters on the Earth’s surface, but from 2017 to 2020 it disappeared, – said Leonid Zotov from the Moscow Astronomical Institute. Sternberg.
Earlier, foreign scientists calculated the probability of death from falling space debris.
