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 ...

A surprising chemical difference between Pluto and Sedna, another dwarf planet in the distant Kuiper Belt, is helping scientists nail down their respective masses, a new study reports. "Kuiper Belt ...

Using data from NASA's now-defunct Dawn spacecraft, scientists have discovered that the dwarf planet Ceres, the second wettest body in the solar system after Earth, could have an interior reserve rich ...

How does a star affect the makeup of its planets? And what does this mean for the habitability of distant worlds? Carnegie's ...

Ammonite was discovered using the Subaru Telescope in Hawaii, with follow-up confirmation from the Canada-France-Hawaii Telescope. Its orbit and size officially qualify it as a distant dwarf planet.

While both planets would likely be locked into a synchronous orbit—with a permanent dayside and a perpetual nightside—the ultrafast white dwarf planet's rotation stretches out the cloud circulation ...
