North Africans contribute to astronomical discoveries

Tunisian Lotfi Ben Jaffel, who is the team leader, and Algerian team member Mohammed Loucif from the Observatory of Alger have made discoveries along with two Europeans and an American that showed that our solar system behaves like a supersonic jet having a shock wave in front of it. Another discovery is also reported that the outer frontier of our solar system is tilted from where it was expected to be.
