Ceres’ bright spots come from salty water below
The mysterious bright spots on Ceres caused a sensation when the Dawn spacecraft first spied them in 2015. Now, they’re known to be salt deposits from a recent or ongoing percolation of briny water from a large reservoir in Ceres’ interior.

Dwarf planet Ceres turns out to be ocean world
Scientists have determined that Ceres, like Europa and Enceladus, is home to an ocean of liquid water. Situated in the asteroid belt between Mars and … Source: https://www.unexplained-mysteries.com/news/338758/dwarf-planet-ceres-turns-out-to-be-ocean-world…
Mystery solved: Bright areas on Ceres come from salty water below
NASA’s Dawn spacecraft gave scientists extraordinary close-up views of the dwarf planet Ceres, which lies in the main asteroid belt between Mars and Jupiter. By the time the mission ended in October 2018, the orbiter had dipped to less than 22 miles (35 kilometers) above the surface, revealing crisp details of the mysterious bright regions Ceres had become known for.

Planet Ceres Is An ‘Ocean World’ With Sea Water Beneath Surface, Mission Finds
The dwarf planet Ceres — long believed to be a barren space rock — is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday. The Guardian reports: Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity, enabling the Nasa Dawn…

We go between the sun and Saturn on July 20
This is Saturn’s yearly opposition. The ringed planet is now opposite the sun in our sky, rising at sunset, highest up for the night around midnight and setting at sunrise. It’s at its brightest and and best for 2020. Source: https://earthsky.org/tonight/saturn-closest-and-brightest…
5 years after New Horizons flyby, 10 cool things about Pluto
Here are 10 of the coolest, weirdest and most unexpected findings about the Pluto system scientists have learned thanks to the New Horizons spacecraft’s flyby of the distant world in 2015. Source: https://earthsky.org/space/new-horizons-flyby-10-cool-things-about-pluto…
Evidence supports ‘hot start’ scenario and early ocean formation on Pluto
The accretion of new material during Pluto’s formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day, despite the dwarf planet’s orbit far from the sun in the cold outer reaches of the solar system.
