The unusual conditions of the first exoplanet detection

The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar.

astronomers have revealed that these planets may be incredibly rare

The processes that cause planets to form, and survive, around pulsars are currently unknown.

over the last 50 years has revealed that this first detected exoplanet system may be extraordinarily uncommon:

Pulsars are a type of neutron star, the densest stars in the universe, born during powerful explosions at the end of a typical star's life.

"[Pulsars] produce signals which sweep the Earth every time they rotate, similarly to a cosmic lighthouse,"

"These signals can then be picked up by radio telescopes and turned into a lot of amazing science."
