3D white dwarf postcard

This postcard is a 3D illustration of a white dwarf star and its Neptune-like exoplanet. White dwarfs are what remains after a stars like our own Sun has exhausted all of its fuel. Since the icy giant planet in this system orbits the hot white dwarf at close range, the extreme ultraviolet radiation from the star strips away the planet’s atmosphere. While most of this stripped gas escapes, some of it swirls into a disc, itself accreting onto the white dwarf.

This postcard measures 148x105mm.
