Volcano-like rupture could have caused magnetar slowdown

On Oct. 5, 2020, the rapidly rotating corpse of a long-dead star about 30,000 light years from Earth changed speeds. In a cosmic instant, its spinning slowed. And a few days later, it abruptly started emitting radio waves.

Study links changes in length of day with climate prediction

Scientists have made a key breakthrough in the quest to accurately predict fluctuations in the rotation of the Earth and so the length of the day—potentially opening up new predictions for the effects of climate change.
