Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past.

Researchers uncover how Mars affects Earth’s orbit, offering new insight into the planetary forces behind ice ages.

Earth’s rotation is slowly slowing, scientists say, meaning days are getting longer, though the change takes millions of years, raising intriguing questions about how time, life and the planet quietly ...

If you have ever heard that Earth will soon start having 25-hour days, it might be right. The idea itself is not wrong. Scientists do expect Earth’s rotation to keep slowing. What often gets lost is ...

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

But in all likelihood, the Earth will not see this time, having been engulfed by the Sun in its red giant phase, around 7.6 ...

The familiar 24‑hour day is based on how long it takes the Sun to return to the same position in our sky, not on an absolutely constant spin rate.
