Around 7,500 light years from Earth in the constellation of Cassiopeia is the beautiful Heart Nebula, or IC 1805. First discovered by William Herschel in November 1787, this romantic cloud of ionised hydrogen and cosmic dust was created by the cluster of stars at its centre, called Melotte 15. The solar winds and radiation of this cluster create the nebula’s love heart appearance.
