The planet would have had to survive the supernova explosion that created the neutron star or black hole that allowed us to see it – and at some point the companion star could explode into a supernova, battering the world with radiation. A paper describing the findings, ‘A possible planet candidate in an external galaxy detected through X-ray transit’, is published in Nature Astronomy today.
