It Came From The Skies

Through remote galaxies

Beyond cosmic rays

Unobserved phenomenon

Traversing nameless space

Outside the solar system

Unidentified zones

Hidden in Nebulae

Composition unknown

Intruding explored cosmos

The menace now exposed

With hypervelocity

And it spreads unopposed

Atmospheric entrance

Disaster imminent

Gigantic collision

Impact event

The surface penetrated

High megaton yield

Rotation mechanism disturbed

Collapsed magnetic field

It came from the skies

Global eruptions

Cracking crusts and plates

Acidic waters

Species disintegrate

Re-entry of ejecta

Radiation intense

Ecology disrupted

The Cenozoic era ends

It came from the skies
