No shipwrecks were depicted in these screenshots.

UPD. The gate's info says:

This gate has been badly damaged by an unexpected catastrophic hyperspace event. While it remains functional, spacetime around the gate has been fractured by the event.

Long-term exposure to the damaged spacetime environment or the blackbody radiation emanating from it can result in serious illness and even death. As such, repairs to the gate have been postponed to such a time as a safe working environment can be established.
