We review the contribution of extra galactic inspiralling double neutron stars, to the LISA astrophysical gravitational wave foreground. Using recent fits of the star formation rate, we show that sources beyond z∗ = 0.005 contribute to a truly continuous background, which may dominate the LISA instrumental noise in the range3 ≃ 10−4- 1 × 10−2 Hz and overwhelm the galactic WD-WD confusion noise at frequencies larger
than νo ≃ 2 × 10−3
