Astronomers have discovered a rare lemon-shaped planet called PSR J2322-2650b orbiting a city-size star. Found using NASA’s James Webb Space Telescope, the Jupiter-size world is stretched by extreme ...

If you’ve ever wanted to get a good look at what the surface of Mars looks like, NASA (and even Google) can quickly offer a view. But if you’ve wanted to get a better look at what the inside of Mars ...

Two small planets might be sculpting an enormous dust ring around the star Fomalhaut, a mere 25 light-years away from Earth. But it’s not too likely that either planet is the notorious Fomalhaut b, ...

Dr. James O’Donoghue, a Japan-based planetary scientist, has made some incredible educational astronomy videos before. Including a video that showcases relative cosmic velocities to understand better ...

Planets start as messy clumps of rock and dust. Gravity pulls everything toward the center. Over time, this force smooths out ...

Your weight changes on other planets and moons due to different gravitational pulls. Weight is how much gravity pulls on you; mass (amount of matter) stays the same. Newton's Law of Gravitation ...

A map of Martian gravity looking down on the North Pole (center). White and red are areas of higher gravity; blue indicates areas of lower gravity. A map of Martian gravity looking down at the South ...

Our solar system officially houses eight planets, but some scientists say there could be a ninth. And that’s not just Pluto aficionados – evidence suggests a huge undiscovered world lurks on the dark ...

Shedding light on the gravity of the situation. Most people do not realize that many of the stars and heavenly bodies they see in the sky no longer exist. In fact, many have ceased to exist for ...

NASA has released a new gravity map of Mars, providing a detailed look at the Red Planet's surface and revealing new information about what lies beneath it. The map was made by tracking subtle ...
