A Southwest Research Institute-led team has reported the first detection of gas on the distant dwarf planet Makemake, using NASA's James Webb Space Telescope (JWST). This discovery makes Makemake only ...

The dwarf planet Ceres, the only dwarf planet in the main asteroid belt, might have once been hospitable for life, according to a recent study. NASA / JPL-Caltech / UCLA / MPS / DLR / IDA Ceres, the ...

Astronomers have directly spotted a rare young planet, WISPIT 2b, still forming within the gap of a dusty ringed disk around a star like our sun—something long theorized but never observed until now.

Our solar system is much like a trail of microcosmic breadcrumbs: Follow the molecular bits as far back as they go, and you'll learn a thing or two about where many of our planets and other celestial ...

Scientists are steadily ruling out habitable conditions on the seven planets of the star Trappist-1. On one of the worlds, a nitrogen gas-rich veil remains a possibility. By Robin George Andrews ...

On August 24, 2006, our solar system lost a planet. It wasn't by cataclysmic destruction, but rather by the vote of the International Astronomical Union, which declared that Pluto, considered the ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...
