The Earth stands alone in the solar system as a habitable world, as far as we know. But that doesn’t mean we don’t get visitors, most often in the form of (usually harmless) asteroids. Some even ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...

There’s a mountain of evidence that having a sense of purpose is correlated with feeling happy. And while an inanimate object such as the moon can’t feel emotions, humans have much to thank our ...

SpaceX's Starship has finally pulled off a successful test flight in a stunning reversal of fortunes for Elon Musk's most ambitious rocket. The uncrewed 403-foot-tall (123 meters) rocket, the largest ...

Scientists may have found the first planet ever detected around our closest “solar twin,” a star called Alpha Centauri A, the same real-life star that was home to the fictional moon Pandora in James ...

NASA's Psyche captured images of Earth and our Moon from about 180 million miles (290 kilometers) away in July 2025. NASA/JPL-Caltech/ASU The Psyche spacecraft is on a six-year journey to reach a ...

Geological evidence, including an Ordovician-era increase in earthquakes, tsunamis, meteorites, and crater formation, suggests a significant celestial event approximately 466 million years ago. A ...

NASA is monitoring a bus-sized asteroid that set to zip past the Earth at some 15,200 miles per hour. The asteroid—"2025 PY1"— will make its closest approach at just 183,000 miles from our planet, ...
