Explore Ceres, the largest asteroid in our solar system, and discover its remarkable ancient ocean and ice-rich crust.

The dwarf planet is a bizarre, cryovolcanic world. However, the organic deposits discovered on its surface so far are unlikely to originate from its interior. The organic material found in a few ...

Eris is three times more distant than Pluto. And its relationship to Pluto — a world demoted since 2006 from the solar system’s ninth planet to a lowly dwarf planet, in large part due to the ...

For decades, Pluto was celebrated as the ninth planet of our solar system. However, in 2006, the International Astronomical Union (IAU) redefined what constitutes a planet, leading to Pluto’s ...

then you really should at least include Eris as well, and once you’ve set that particular precedent, you’ll find it necessary to include a lot of other dwarf planets. Without a firm lower ...

The organic material on the dwarf planet Ceres is probably of extra-Ceresian origin: a recent study concludes that asteroids from the outer asteroid belt that crashed into the dwarf planet brought ...

the researchers looked for previously unknown deposits of organic material on dwarf planet Ceres. With its location in the middle of the asteroid belt between the orbits of Mars and Jupiter, the body ...

The planet, if it is indeed a planet ... an unremarkable orange K-class dwarf with just 64% the mass of our sun. As Gaia plotted the star's proper motion in the sky, it noticed that the star's ...

The brown dwarf, not quite a planet or a star, is Gaia-5b. Respectively, they are 244 and 134 light-years away. "This discovery is an exciting tip-of-the-iceberg for the exoplanet discoveries we ...

The aptly named Dwarf 3 will make you think again ... This isn’t a great telescope for shooting planets – even the moon and sun (solar filters are supplied) don’t exactly fill the frame.
