A billion years ago, days lasted 19 hours: the balance between the oceans, the atmosphere, and the Moon slowed down the Earth ...

Astronomers using NASA’s Hubble Space Telescope have measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the ...

Ancient Chinese astronomers observed a solar eclipse in 709 BCE with remarkable detail. These old records are now helping scientists understand Earth' ...

Astronomers have made an unexpected discovery about the planet TOI-3884b, which orbits its star at a crazy angle. The planet’s orbit is tilted by around 62 degrees compared to the star’s rotation, and ...

An instantaneous cessation of Earth's rotation would result in catastrophic, planet-wide devastation due to the inertia of objects on the surface moving at high speeds (approximately 1000 mph at the ...

Using new data from NASA’s Cassini spacecraft, researchers believe they have solved a longstanding mystery of solar system science: the length of a day on Saturn. It’s 10 hours, 33 minutes and 38 ...

Jupiter is the largest planet in the solar system, known for its massive size, strong gravity, powerful storms and many moons ...

A planet's north pole is defined by its position relative to the solar system's invariable plane. The invariable plane is a fixed reference point perpendicular to the solar system's rotation. A planet ...
