On these days the Earth will be measurably—and, so far, unaccountably— accelerating its rotation, shaving from 1.3 to 1.5 milliseconds off of the usual 24 hours the typical day gets.

Earth is spinning faster this summer, leading astronomers to notice that some days have clocked in at slightly less than the standard 24 hours. This stack composite photo shows a paddy rice field ...

On July 10, the shortest of 2025 so far, Earth completed its daily spin 1.38 milliseconds faster than usual, per data from the International Earth Rotation and Reference Systems Service (IERS).

The “Largest Piece of Mars on Earth” just sold at auction for about $5.3 million— $5,296,000, to be exact. Popular Science has reached out to Sotheby’s for confirmation of the sale price.

A 2023 study showed a day was approximately 19 hours in Earth's early history. July 5, 2024, was the shortest day ever, 1.65 milliseconds shorter than the usual 86,400 seconds, said MIT ...

These rocks are unambiguously dated at 4.03 billion years old, marking the boundary between the Hadean Eon and the next chapter in Earth’s history: the Archean.

This potential sample of Earth’s early crust is the subject of a long-standing debate among geologists: is it the world’s oldest rock, or merely extremely old?

For context, Earth's "normal" or background extinction rate is incredibly low: estimated to be between 0.1 and 1 species per 10,000 species every 100 years. This natural turnover is a part of ...

A Soviet-era spacecraft plunged to Earth on Saturday, more than a half-century after its failed launch to Venus. The European Union Space Surveillance and Tracking confirmed its uncontrolled ...

Students, parents and teachers are blasting this year’s Biology Regents for failing to include material kids studied, instead asking unexpected questions about earth science and chemistry.

Funding for science is very much on the chopping block in President Trump's proposed budget. It's a fraught moment for NASA, particularly for those focused on earth science and not human space ...
