We present X‐ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM‐Newton satellite. Only one component of the binary can be observed in optical‐UV. New X‐ray observations show that the previously invisible component is a very hot compact star. This finding allows us to deduce rough values for the basic parameters of the binary. With a high probability the total mass of the system exceeds Chandrasekhar limit and makes the SBS 1150+599A one of the best candidate for a supernova type Ia progenitor
