A team of astronomers believe they may have discovered a new dwarf planet—just like Pluto—on the edge of our solar system.

At the very edge of our solar system, beyond the grasp of Neptune and even past the icy sprawl of Pluto’s domain, a new ...

Astronomers have announced the discovery of a new dwarf planet in our solar system, named 2017 OF201. Located far beyond ...

WD 1856+534b—a freezing world with a surface temperature of -125 degrees Fahrenheit—exists where planets are normally scoured ...

Dubbed "Teleios" after the Greek word for "perfect," the object is what's known as a supernova remnant (SNR), a glowing cloud ...

Astronomers have spotted brown dwarf pairs before, but these two whip around at much closer range. They orbit each other every 12 days, less than the time it takes for the moon to circle the Earth.

The other half comprises stars that circle other stars ... in which a star similar to our sun orbits tightly around a white dwarf -- a hot, dense core of a burned-out star. A cataclysmic variable ...

Each of the newfound exoplanets is slightly larger than our planet, and both circle the same red dwarf star. The exoplanets were spotted by NASA's Transiting Exoplanet Survey Satellite (TESS ...

In contrast, dwarf galaxies have often been underrepresented in such studies because of their low luminosity and the challenges associated with sparse sampling. However, the USTC research team has ...

Astronomers have made a first-of-its-kind discovery — a white dwarf star with two completely different faces. White dwarfs are burnt remains of dead stars. Our sun will become a white dwarf in ...
