Earthquake scientists rely on distant seismic instruments to infer how faults rupture during large earthquakes. This video ...

Astronomers witness first moments of planet formation as rock grains crystallize around distant star HOPS-315.

Astronomical discovery: supersonic gales of 20,500 mph batter the exoplanet WASP-127b, breaking cosmic records for ...

Earth has experienced both hot and cold periods over time, though warm times have been more common. That’s true of the last 485 million years, as seen in this timeline reported in 2024. Our genus, ...

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby ...

On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth completed its rotation approximately 1.3 to 1.6 milliseconds faster than ...

Atomic clocks — among the most precise instruments humans have ever built — have been keeping track of Earth’s spin since the ...

Earth is spinning faster, making July 9, 2025, one of the shortest day since 1960 by 1.3 to 1.6 milliseconds, primarily due to the Moon's alignment. While imperceptible in daily life, this speedup may ...

Long-term changes in the planet's spin speed largely stem from Earth's core acting in unpredictable ways, researchers say.

Here’s what you’ll learn when you read this story: Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before ...

Despite being covered in impact craters that could potentially send pieces of the planet into space, we have never found a piece of Mercury. Until, just maybe, now.

Here on Planet Earth, the base was already substantially evacuated and the missiles were intercepted with no casualties reported. All sides said Iran gave advance notice that the attacks were coming.
