Astronomers find neutron star at centre of Supernova 1987A

A team of astronomers led by Dr. Phil Cigan at Cardiff University have announced that they have found evidence that a neutron star is present at the centre of the remnant of Supernova 1987A.  The star has evaded detection for 30 years, but using ALMA, the team was able to find a region in the centre of the object where the dust is brighter than its surroundings.  More information is available in the press release from Cardiff University as well as in the article in The Astrophysical Journal.
