It began, in fact, with a supernova: thus, from the beginning, it was a causal chain shaped by stupendous violence.

The star was a blue supergiant, twenty times the mass of Earth’s sun, fifty thousand times as bright. It had formed a mere million years ago.

Nevertheless there was life here.

It had come drifting on the interstellar winds from older, more stable systems, and taken root on worlds which cautiously skirted the central fire.

But the hydrogen fuel in the star’s fusing core was already exhausted.

The core, clogged with helium ash, began to burn that ash itself, helium nuclei fusing to carbon. And the carbon compacted to neon, the neon to oxygen … At last iron nuclei snowed, inert, on the centre of the star.

The core’s free-fall implosion took fractions of a second. The star’s outer layers were suddenly suspended over an effective vacuum. They collapsed inwards, the infalling layers crashing onto the rigid core remnant, and rebounded violently. The reflected shock wave was hurled out of the centre of the star, dragging away the star’s outer layers with it …

For a week, the dying star outshone its Galaxy.

For forty years the expanding shell of matter travelled, preceded by a sleet of electromagnetic radiation: gamma rays, X rays, visible light. A human eye might have seen a brilliant blue-white star grow suddenly tremendously luminous, fifty times as bright as the Moon, as bright as all the other stars in the sky combined.

But Earth did not exist, nor even, yet, the sun. The garish light of the supernova washed, instead, over the thin tendrils of a gas cloud: cold, inert, stable.

And in any event no human telescope could have detected, rushing before the light storm, a single, delicate, spidery silhouette.

A fleeing craft.
