Experts spotted a new, young planet with a strange behavior orbiting a dwarf star. It is 10 times bigger than the Earth and ...

Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like ...

Astronomers have discovered the weirdest planetary system ever seen, consisting of a planet rolling around rare binary ...

The Webb telescope has spotted exoplanets circling white dwarf stars, proving that planets can survive their star’s violent ...

The discovery of natural satellites on Saturn assists researchers in understanding the dynamics of orbits, resonances, and the stability of planetary systems in general ...

Most meteorites are small — pebble-sized or smaller — chunks of rocky material that, in most cases, get buried in the soil or ...

Webb has two decades ahead of it, but it's already captured some stunning images. Here are 35 of our favorites.

When Voyager 2 flew past Uranus in 1986, it provided a close-up snapshot of the sideways planet. What it saw resembled a bland, blue-green billiard ball. By comparison, Hubble chronicled a 20-year ...

Astronomers have long predicted that two orbiting white dwarfs are the cause of most type 1a supernova explosions. While the pair are in close orbit, the heavier of the two theoretically accumulates ...

The exoplanet is about nine times the size of Jupiter, and its orbit takes it three times as far from its star as Neptune is from the sun. That helped scientists pick out the planet in the star's ...

Pluto is one of several dwarf planets floating around in our solar system. One of these dwarf planets actually orbits in between Mars and Jupiter ... A year on Mars, by comparison, is roughly ...
