Yes,
There are several wrecks around the Unkown Jumphople in Omnicrom Alpha. Everyone of the red "X"`s are ships that are wrecked.

Doh! Didn't know that. Thanks.

LOL, now you know, everything on the map has an explanation on it

just put your cursor over it

Also, you might find it helpful when you're in an area in which you suspect there's something to find, to change your targeting list mode (the display in the lower left of your HUD) to "all" or "solar", etc., and scrutinize the items on the list, paying attention to their icons and the distances from you. Using the zoom finction on your map display for the area around you--or the area where you suspect there's something to find--is also useful.

My experience indicates that those red "x"s appear only either after you've bought info about them or have come physically fairly close.

As has been said (quite a few times) elsewhere, using the patrol filter on the map and visiting the intersections and/or convergence points can be instructive (and prfitable), too.

Happy looting!
