Concept art depicting two white dwarf stars of equal mass but differing temperatures. The hotter white dwarf on the left appears slightly larger and puffier, surrounded by a glowing blue halo, while the cooler white dwarf on the right looks more compact and has a slightly less pronounced halo. The background consists of a dark starry sky with faint nebular patterns.
