The rotation is slowing down due to tidal friction from the Moon, lengthening the day by approximately 1.7 milliseconds per ...
Our 24-hour day measures Earth’s rotation relative to the Sun, known as a solar day. This is slightly longer than Earth’s ...
Seismic waves passing through the Earth have revealed that the inner core of our planet is now rotating out-of-sync with the layers above it. Update: As reported below, research from January 2023 ...
A globe was the first thing I ever bought with my own money. I was maybe 5 years old, and I was really excited to take it home. As I quickly discovered, you can spin it in the direction that the earth ...
Our planet has been slowing down ever since it formed. A day on Earth was about 21 hours long about 440 million years ago. When the dinosaurs stomped around, it was about 23 hours long, fossils and ...
The latest findings in Earth science are brought to you by ancient astronomers who observed the heavens as much as 2,700 years ago. Thanks to hundreds of records of lunar and solar eclipses carved in ...
Physicists at NASA and Princeton generate electricity from the Earth's rotation: could wind energy be our energy source of ...
Earth's days are slowly getting longer. This change is driven by the Moon's gravity and shifts in Earth's mass due to melting ...
Polar ice melt driven by climate change is affecting Earth's rotation, according to new research. We may have to adjust timekeeping by "skipping" a second in 2029. A human-driven change in the Earth's ...
The familiar 24‑hour day is based on how long it takes the Sun to return to the same position in our sky, not on an ...
WASHINGTON — Wednesday will be slightly shorter than usual, but you probably won't notice the difference even if you're watching the clock closely. Earth is expected to complete a full rotation on ...
Like you, I'm given to wondering about "what ifs" to better understand the assumptions we make about the world. One of my favorites is what if the Earth stopped rotating? Let's just say things would ...
