Earth’s rotation is slowly slowing, scientists say, meaning days are getting longer, though the change takes millions of ...

But in all likelihood, the Earth will not see this time, having been engulfed by the Sun in its red giant phase, around 7.6 ...

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 ...

Does it feel like there's not enough time in the day for everything? Well, that could be because some upcoming days are actually getting shorter. In fact, today might just be the shortest day you'll ...

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 ...

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 ...

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 ...

While the Earth on June 29 did indeed record its shortest day since the adoption of the atomic clock standard in 1970 — at 1.59 milliseconds less than 24 hours — scientists say this is a normal ...

Earth’s solid metal core may no longer be spinning relative to the vast mass of the surrounding planet thanks to what appears to be a recent slowdown, according to the results of a new study. Nestled ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also ...
