I have it on good authority
That it was J-Rod the Roswell Grey making good his escape from the secure facility. The bang was obviously that tiny one entity pod hidden in that desert cave for >70 years jumping to hyperspace, though it didn't have interstellar capability it worked well enough to get the hell out of Dodge (tm) in this case out past Pluto.
Even he didn't see a "No Deal" coming, time warp bracelet or not.
Turns out that he sent an SOS message using HFGW pulse wave the day before LIGO was officially switched on, and those weird pulses everyone thought were calibration test signals turned out to be far more interesting. Ironic that they used reverse engineered technology from the first craft to almost detect the second but thanks to a bit of inside knowledge and misdirection it was later dismissed as noise.
Pick up should be any day now.
