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
