His particular interest is in novae and supernovae, and has been awarded by the BAA with the Walter Goodacre Medal - the highest honour the association awards - and honoured by the Royal Astronomical Society.

If the first stars are born as a multiple stellar system rather than as an isolated single stars, elements ejected by the supernovae are mixed together and incorporated into the next generation of stars.

These heavy elements are what cosmic dust is made of, and it is, therefore, difficult to explain the origins of the dust without attributing some of it to supernovae.

This will give astronomers deeper insight into short-lived astronomical phenomena such as supernovae, the huge explosions that mark the end of a massive star's life.
