Planet Earth is spinning a little faster today — resulting in one of the shortest days of the year. But the change will be so minuscule you won’t even notice. We’re talking even less time than the ...

One day in the next couple of years, everyone in the world will lose a second of their time. Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice ...

The Earth spins on its axis once every 24 hours, right? Actually, no. The length of each day varies widely by a few milliseconds. According to the International Earth Rotation and Reference Systems ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

New research by two scientists at Peking University in Beijing, China, suggests that Earth's inner core may have slowed or possibly reversed its rotation during the past decade. On Tuesday, Jan. 24, ...

The days are getting shorter and not just because summer is waning in the Northern Hemisphere. On Tuesday, Aug. 5, Earth's solar day will be ever so slightly shorter than usual 24 hours, according to ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

Climate change is causing the ice masses in Greenland and Antarctica to melt. Water from the polar regions is flowing into the world’s oceans –and especially into the equatorial region. “This means ...

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 ...
