We present the discovery of diffuse optical line emission in the Centauruscluster seen with the MUSE IFU. The unparalleled sensitivity of MUSE allows usto detect the faint emission from these structures which extend well beyond thebounds of the previously known filaments. Diffuse structures (emissionsurrounding the filaments, a northern shell and an extended Halo) are detectedin many lines typical of the nebulae in cluster cores ([NII]$_{\lambda6548\&6583}$ ,[SII]$_{\lambda 6716\&6731}$, [OI]$_{\lambda 6300}$,[OIII]$_{\lambda 4959\&5007}$ etc.) but are more than an order of magnitudefainter than the filaments, with the faint halo only detected through thebrightest line in the spectrum ([NII]$_{\lambda 6583}$). These structures areshown to be kinematically distinct from the stars in the central galaxy andhave different physical and excitation states to the filaments. Possibleorigins are discussed for each structure in turn and we conclude that shocksand/or pressure imbalances are resulting in gas dispersed throughout thecluster core, formed from either disrupted filaments or direct cooling, whichis not confined to the bright filaments.
