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 ...

New simulations examine whether the seven planets in the TRAPPIST-1 system could host moons, showing that only small, close-orbiting moons could remain stable over long periods ...

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 ...

Astronomers photographed a baby planet, WISPIT 2b, during its formation process within a dusty ring around its star system.

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, ...

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 ...

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 ...

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 ...

Mercury has long baffled astronomers because it defies much of what we know about planet formation. A new space mission ...

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 ...
