artist’s rendition of janus, the blue-tinted dead cinder of a star that is composed primarily of hydrogen on one side and helium on the other (the hydrogen side appears brighter). the peculiar double-faced nature of this white dwarf star might be due to the interplay of magnetic fields and convection, or a mixing of materials. on the helium side, which appears bubbly, convection has destroyed the thin hydrogen layer on the surface and brought up the helium underneath.
