Instead, physicists suggest the universe’s current expansion phase was preceded by a big crunch contraction and possibly a bouncing universe with infinite prior cycles of expansion and contraction. *The next nearest planet to our solar system A temperate Earth-sized planet has been discovered just 11 light-years away. The new world named Ross 128 b is currently the second-closest temperate planet ever detected – the nearest being Proxima b which orbits the star Proxima Centauri some 4.25 light years from Earth. *Dawn explores Ceres’ interior evolution Scientists have begun studying the internal structure and composition of the dwarf planet Ceres finding a close relationship between its internal evolution and its surface features. The findings used data collected by NASA’s Dawn spacecraft to analyse Ceres’ surfac
