Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) — an international observatory co-operated by the US National Science Foundation’s National Radio Astronomy Observatory (NRAO) — have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star. The team also confirmed this flash of light to be one of the most energetic short-duration gamma-ray bursts ever observed, leaving behind one of the most luminous afterglows on record. The results of the research will be published in an upcoming edition of The Astrophysical Journal Letters.

Gamma-ray bursts (GRBs) are the brightest and most energetic explosions in the Universe, capable of emi...
