A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of conventional astronomy theory, and is making experts reconsider ...

The dwarf planet Ceres hosts a frozen ocean that is almost pure water ice at its surface and becomes ‘dirtier’ with depth, modelling suggests 1. The work reconciles conflicting evidence ...

If the planet did exist, it would be on an extremely strange trajectory around the Sun —so strange, in fact, that some astronomers say it could challenge our understanding of planetary science.

A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected ...
