“Cow” and “Koala” lead explosive new class of space signals

The universe is full of powerful explosions from various sources, and now astronomers have described a brand new class of space signals. Named fast blue optical transients (FBOTs), these events are very bright and throw off incredible amounts of energy in a short amount of time.

> A population of particular recent interest is “fast-evolving luminous transients” or “fast blue optical transients”. A consistent definition of this class does not yet exist; these terms typically refer to transients with rise times and peak luminosities too fast and too luminous, respectively, to be explained by the radioactive decay of 56Ni. Although they likely arise from a variety of progenitors, fast luminous transients are primarily found in star-forming galaxies and therefore are thought to represent a variety of poorly understood endpoints of massive-star evolution.

So, not alien intelligence. Oh well, it was worth a try.
