A team of scientists has investigated how Earth’s twin became so inhospitable, and whether the same will happen to our planet ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases the size of the Moon’s orbit. This means that the Moon gets slightly farther ...

The brightest, best date for spotting Saturn is fast approaching. Here's how to see the ringed planet from Indiana.

The Moon is getting 1½ inches (3.8 centimeters) farther away from the Earth every year. Scientists measure the distance to the Moon by bouncing lasers off mirrors placed there by space probes and ...

New simulations show carbon enabled Earth’s inner core to solidify under realistic cooling, solving the nucleation paradox.

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its momentum goes to the Moon. To put it another way, as the Moon's orbital momentum ...

Changes in rock formations from before and after the mass extinction event 66 million years ago may reflect how dinosaurs ...

Ancient crystals reveal that Earth began recycling its crust and forming continents billions of years earlier than scientists ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new ...

Dinosaurs had such an immense impact on Earth that their sudden extinction led to wide-scale changes in landscapes—including ...

The greatest challenge facing astrobiologists is that there is only one planet known to us that has life. Of all the bodies ...
