What did Newton understand that was such a revolution? Can someone just... explain gravity to me? Let's start with a ...

20 years to articulate his thoughts on gravity to his satisfaction. His biggest problem? The question of whether the Earth's gravitational influence could extend all the way to the Moon.

The force of gravity is weaker on the Moon than on the Earth, so here you can jump much higher! Gravity also acts between the Moon and the Earth and keeps the Earth in orbit around the Sun.

President Trump launched the Artemis program to return U.S. astronauts to the moon for the first time since Apollo. Now, the ...

The moon's orbit is elliptical, or oval-shaped, meaning as its distance from our planet changes, its apparent size changes, too — but only slightly. If you're an avid moon-watcher, you might ...

The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under ...

The moon, is only a quarter the size of the Earth. Gravity holds it in an ongoing embrace, its orbit taking nearly 27 and a half days to complete. The planet Earth is about 4.5 billion years old.

The lander, Blue Ghost, fired its engines for four minutes Thursday to propel the spacecraft into lunar orbit ahead of a ...

Firefly Aerospace's Blue Ghost captured some stunning sights on its way to the Moon's Mare Crisium basin.

Firefly Aerospace's moon-bound spacecraft has provided the closest thing to a reflecting pool in space, showing Earth as an imposing monument, stacked on top of another Earth. The illusion is a ...

There's a small chance that the asteroid could collide with Moon. While scientists have doubled the odds of asteroid 2024 YR4 colliding with Earth in 2032, new calculations show that there was a ...
