Hotter than the sun: an extremely hot brown dwarf has been discovered about 1,400 light years away from us

The brown dwarf is part of a new pair system that may advance our understanding of the evolution of stars and planets under extreme radiation conditions

Ring Superintendent - An artist's illustration of the ring system of a young giant or brown dwarf planet J1407b. The rings appear to cause a solar eclipse and hide the Sun-like but younger star J1407 as discovered in 2007. Illustration by Ron Miller for the University of Rochester

In another solar system, a "super Saturn" with a huge ring system and possibly a moon will be discovered

Artist rendering of ULAS J222711-004547. This recently discovered brown dwarf is characterized by a thick layer of clouds composed of mineral dust. These thick clouds give ULAS J222711-004547 its strong red color, which distinguishes it from "normal" brown dwarfs. Image: Neil Cook, Center for Astrophysical Research, University of Hertfordshire.
