A new classification scheme may help us better understand planet formation — including the history of our own family of worlds.

Astronomers have confirmed the existence of four planets orbiting a star less than 6 light-years away with help from some of ...

MAROON-X was specifically designed to detect tiny exoplanets orbiting red dwarf stars by detecting the minuscule ...

The Radcliffe Wave is a massive, undulating structure filled with dense clouds of gas and dust, stretching across several ...

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in ...

Planets beyond our solar system are called exoplanets. Those orbiting Barnard’s star are among the smallest of the more than 5,800 exoplanets discovered since the 1990s as astronomers refine ...

The solar system is a region of space, and all of the objects contained within which are gravitationally bound to the sun. This means all the planets and moons, all of the asteroids and comets ...

“The telescope was named after Johannes Kepler, who, four centuries ago, was the first scientist to appreciate that the planets in our solar system move on slightly elliptical rather than circular ...

"We know from our own solar system that giant planets bring a little bit of chaos to space. They can perturb orbits and give a little bit of extra boost to the velocities of objects, which is all ...

That same cloud gave rise to our entire solar system, including our star, the sun. Keep reading to learn more about Earth's different layers, its atmosphere, and what makes the "blue planet" unique.
