The scientists were able to track the origin of this explosive event to a small, bright galaxy located around 1.7 light-years away. The galaxy has an irregular structure and is in the midst of intense star formation.

Methinks they fucked up their distance units here. 1.7 light years is really close cosmically speaking. That’s closer than the Alpha Centauri system, which is 4.246ly away at closest, and the closest non-sun stars to earth…

So I wonder where it ACTUALLY was. I’m guessing they forgot “million” in there.. 1.7 million light years away is far far more likely, but with magnitudes of 10 billion suns, it could very well have been 1.7 billion light years away, as that would put it much earlier in the universe when those ultramassive stars and systems were more common.
