Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Earth's magnetic poles have reversed numerous times, a phenomenon driven by chaotic processes in the planet's outer core. Recent research suggests some reversals may have been missed, particularly ...

Comet 41P slowed its rotation to a halt and then began spinning in the opposite direction, surprising scientists.

Scientists say the Moon is slowly shrinking as its interior cools and contracts. While it is not disappearing, researchers ...

It’s not so much a traditional clock as it is a measuring tool, but it’s all that’s needed to do some basic, interplanetary calculations As an example, the team suggests a scenario in which a ...

Earth’s days are not always exactly 24 hours, and recent measurements show unusual fluctuations. Some days are getting shorter, others slightly longer — and scientists are still trying to understand ...

These 10 space facts are truly out of this world. We will present you with 10 statements in this true or false space quiz.

The number of these circumpolar stars increases as you move toward the North Pole. There are no circumpolar stars at the equator. Every star and constellation rises in the east and sets in the west ...

Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.

Far below the deepest boreholes, Earth’s core appears to keep its own rhythm, a slow magnetic throb that repeats roughly every seven years. Using a mix of satellite and ground measurements, ...

Scientists traced star-forming gas clouds in a nearby lenticular galaxy, NGC 1387, offering new insight into early-type ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...
