    LIGO gets back to work

    LIGO, the US observatory that announced the first detection of gravitational waves in 2016 , will be switched on again today after upgrades that will increase its sensitivity by 40 per cent. It will now be able to survey an even larger volume of space for wave-making events such as collisions between black holes. Astrophysicists hope the resulting torrent of data will give us answers to some big questions, such as how do black holes pair up; what is inside a neutron star; and can we see inside a supernova?
