Cosmic Signatures
Cosmic Signatures (not to be confused with their counterpart Cosmic Anomalies) are a part of Exploration in EVE. Generally speaking they are the harder, more intense and rewarding of the two. They need to be located by probing before they can be accessed.

Site Respawn Mechanics
Much of the information surrounding the respawn mechanics of cosmic signatures is based on theory, with little hard data offered by CCP. Nevertheless, the sites will respawn immediately after being fully cleared by a player. It is unknown what range the new site will spawn in (if it's in the same region or not) or whether it will be of the same or similar type as the one cleared. Note that, based on this information, we know that sites will not respawn after daily downtime. They will only spawn when sites are cleared somewhere else within the game world.
