You might think the length of a day never varies—exactly 24 hours. You'd be wrong, at least if you count days in milliseconds, as physicists do.
In recent decades, astronomers have reconstructed a fairly complete scenario for planet formation, from minute dust motes clumping together to the emergence of rocky spheres thousands of kilometers across, like Earth, or ...
The eruption of the Anak Krakatau volcano in early September 2026 had effects far beyond the rumbling ground and ash that blanketed nearby areas.
Astronomers have discovered a faint population of young stars extending far beyond the known edge of the nearby spiral galaxy Messier 74. The finding suggests the galaxy is nearly twice as large as previously measured. The ...
In some parts of the world, the sea barely rises and falls with the tides. In others, the difference between high and low tide is dramatic. Along Western Australia's Kimberley coast, for example, it can exceed 10 meters (33 ...
The race to space continues, with the number of rockets launched increasing every year.
When the universe was still in its infancy—only 500 million years after the Big Bang, or about 3% of its current age—some of the universe's earliest stars and galaxies had already formed. Astronomers have long predicted that ...
Soils harbor some of the most diverse life on Earth. Soil nematodes play crucial roles in maintaining ecosystem functions. Yet how their diversity changes across large landscapes, and what drives those changes, remains poorly ...
The asteroid Bennu orbits the sun once every 1.2 years and approaches Earth every six years, passing within around 300,000 kilometers. NASA took advantage of this to collect material from the celestial body. In a spectacular ...
Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's Centre for Quantum Technologies (CQT) keeps time—and with record-setting accuracy, according to results ...
