Exo

Look for the wobbling star

A gravitational embrace

Binary minima

Eclipsing from the deep

By a star a billion times as bright

A planet has the faintest light

Pulsar; a cosmic radar

Revealed in eclipse

Waiting in the darkness

Close by tidal distortion

Data to be measured

Calculated and precise

A lead, a gift, a spectral shift

A visual contortion

Decipher variations

The modulating light
