A Dec. 5 Instagram post (direct link, archive link) shows a TikTok in which a man reads and shows screenshots from various NASA reports that reference a "flat, non-rotating earth" model. "NASA ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

Scientists recently discovered that Earth’s dense inner core may have stopped rotating relative to the surface. But that change is not likely to have noticeable impacts on our daily lives. Scientists ...

If you haven’t accomplished as much this summer as you had hoped to, you can blame forces far beyond your control: a few of these dog days, by one measure, are among the shortest you’ve ever lived ...

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 ...

Earth’s Rotation Day 2026, observed on January 8, highlights how Earth’s constant rotation shapes day and night, climate, ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

The inner Earth is a mysterious place, and now scientists may have uncovered a strange new secret. According to a new study, the Earth’s inner core may have recently stopped rotating, relative to the ...

On those three days, just over a millisecond is expected to be shaved off the standard 24-hour day. Of course, you're unlikely to notice such a miniscule difference in your day. But scientists who ...

Our planet may have had a recent change of heart. Earth’s inner core may have temporarily stopped rotating relative to the mantle and surface, researchers report in the January 23 Nature Geoscience.

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, ...
