“This is the current era, in which matter is arranged in the form of stars, galaxies, and galaxy clusters, and most energy is produced in stars. Massive stars use up their fuel very rapidly, in as little as a few million years. Eventually, the only luminous stars remaining will be white dwarf stars. By the end of this era, bright stars as we know them will be gone, their nuclear fuel exhausted, and only white dwarfs, brown dwarfs, neutron stars and black holes will remain.”
@moonhat@sammydog01 more likely this one since the other is oval and yours appears round. (Truth be told, I wouldn’t have been likely to find it without the Julia-knight-peony hint from the above link).
It also looks like it is available in several different colors/shapes/sizes.
