Ripropongo anche il post pubblicato nel topic "Ufo Hoaxer".
La spiegazione fornita dalla NASA è esatta. E' tutto spiegato in questo articolo pubblicato qui:

Questo che segue è un esempio di illuminazione usata dalle imbarcazioni impegnate nella pesca di un particolare tipo di calamaro (Illex argentinus):
Squid fishermen use bright lights to draw fish and squid toward the sea surface at night.

Altra foto esemplificativa:
dalla fonte (arctracer.com):
Fishing for squid at night with bright lights was very common in both Malaysia and Thailand. We did not understand their technique completely, but the boats seemed to be anchored or drifting while they fished. The squid were apparently attracted by the lights and caught in nets.
Secondo quanto letto, queste luci servono per attirare verso le imbarcazioni e la superficie del mare ciò di cui il calamaro si nutre (il Phytoplankton).

L'insolita (ma ben nota in quelle acque) flotta peschereccia era argomento già all'attenzione dei media, tant'è che nell'

And with Argentina and the Falkands failing to cooperate on fisheries management, there is a fishing fleet so large its lights can be seen from space working the area...
BUENOS AIRES, Argentina (AP) — It was a rare victory in the squid wars: Argentina’s coast guard cutter Thompson fired warning shots at two Chinese trawlers, blocking their escape into international waters. Ten tons of squid were found in the holds of the Lu Rong Yu 6177 and 6178 after they were hauled into port on Christmas Day.
But this was just the first such capture in two years, a minor disturbance to the hundreds of unlicensed, unregulated fishing vessels that exploit the South Atlantic, pulling out an estimated 300,000 tons of ilex squid a year.
