Error Message when Clipping Rasters

[SamCarless]

I'm new to using ArcMap and I'm trying to clip some light rasters but I get error messages that I don't understand. Does anyone have any ideas?

[DanPatterson_Retired]

the output filenames are too long and contain spaces

you seem to be clipping the raster with the whole world

the file doing the clipping and/or the raster don't have a defined coordinate system

that's all I can see right now
