Researchers have located a new system with at least six planets, of which a record-breaking half fall into the category of super-Earths - planets more massive than Earth but less massive than planets like Uranus or Neptune - in the zone around the star where liquid water could exist, making them likely candidates for life.
Two astronauts on board of the International Space Station started a daring spacewalk to clear space for a Russian space module to be installed later this year.
