A study published in Nature Geoscience suggests that the gradual slowing of Earth’s rotation over billions of years may have ...

While Earth's slowdown is not noticeable on human timescales, it's enough to work significant changes over eons. One of those ...

Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have confirmed the discovery of two rocky exoplanets ...

Despite seeming like Earth's twin, Venus is a strange and mysterious place. Scientists haven't known what made it so odd, but that might have just changed.

A new model called StarryStarryProcess lets scientists map star spots with precision, improving how exoplanets are studied. By factoring in both transits and stellar rotation, it provides richer ...

Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...

Mars is rotating more quickly than it used to, according to data that NASA’s InSight lander collected on the red planet. The now-retired InSight was armed with a suite of instruments, including ...

NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

Early in the planet's history, Earth's rotation may have even been shorter than 10 hours, Konstantin Batygin, a professor of planetary science at Caltech, told Live Science in an email.

From its scorching temperatures to its oddball rotation, there's a lot to learn about the second planet from the sun.

This is how long a year is on other planets in our solar system, beginning with Mercury at about 176 Earth days to complete its orbit.
