Scientists have discovered a giant exoplanet with a mass almost 13 times that of Jupiter in an evolved binary system. This is the first confirmation of an exoplanet in a system of this kind.
Excavators have started digging out rock to make way for the foundation and pier that eventually will support the Giant Magellan Telescope atop the 2,500-metre (8,200-foot) peak in the Atacama Desert in Chile.
