Strange Object in Precursor Sytem

[donkavash]

I found a strange wreck with blinking red light near the center of the precursor system. When destroyed it has a very unique artifact, a diary writen on tablet by an extinc precursor.
Is it part of the quest or just an easter egg?
Can i keep it, sell it, or just like all artifacts, confiscated by the aliens?

Doesn't seem to have any use, just take a screenshot as a trophy.
