A transiting exoplanet has revealed a huge "spot" near the pole of its tiny M-dwarf parent star. The spot has been around at least 7 years and occupies 7% of the sun's surface.

A CCTV video from Myanmar has revealed the first direct footage of a curved fault slip during an earthquake—confirming long-held geological theories and deepening our understanding of rupture dynamics ...

Since 2020, Earth has been rotating unusually fast on its axis, leading scientists to consider whether we should correct for the shorter days.

An icy object in perfect sync with Neptune reveals new details about planetary migration and unseen bodies far beyond the Kuiper Belt.

It takes Earth 24 hours, or 86,400 seconds, to make one full rotation around its axis, but Earth's rotation isn't perfectly ... But during certain points in the Moon's elliptical and tilted orbit, ...

Earth to experience shortest days on July 22 and August 5, 2025 A typical day is defined by the time Earth takes to complete one full spin on its axis—roughly 86,400 seconds or 24 hours.

Another culprit could be powerful earthquakes knocking the Earth off its already tilted axis. In 2011, scientists found that a 9.0 earthquake in Japan may have been ferocious enough to shorten days on ...

The simple answer to this, though, is that our seasons and weather depend on the way the Earth is tilted towards the sun and not how close or how far the two celestial objects are from each other.

Since Kepler's laws of motion dictate that celestial bodies orbit more slowly when farther from the sun, we are now moving at ...

The reason is that the Earth is doing two things at once: It's spinning on its axis, which causes the sun to appear to move across the sky.
