Just discovered:

Teleios

Ancient Greek for "perfection"

A massive spherical bubble, 11, 46, or 157 light-years across (they aren't sure yet)

Could be from a white dwarf slurping up a companion star, exceeding a mass limit, and exploding

In our Milky Way, not an ORCS (Odd Radio Circles at intergalactic distances)

Discovered by Miroslav Filipović and team of Western Sydney University using the Australian Square Kilometre Array Pathfinder (ASKAP)
