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.
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,”
In 1992, the first ever exoplanets were discovered orbiting a pulsar called PSR B1257+12
The planetary system is now known to host at least three planets similar in mass to the rocky planets in our Solar System
