Astronomers Find Distant “Forbidden Planet” In “Neptunian Desert”

And more Earth-like planets could be found hiding in nearby star systems.


An international team of astronomers says it’s discovered a rogue exoplanet three times the size of Earth — in an orbit that was thought to be impossible, meaning more Earth-like planets could be found hiding in nearby star systems.

No exoplanets with gas atmospheres were previously thought be able to orbit this close to a star — a region known as the “Neptunian Desert” — as the gas would evaporate and leave just a rocky core. Until, that is, this team located NGTS-4b, which they’re calling a “forbidden planet.”

The astronomers believe NGTS-4b could’ve either just moved into position in the last million years, or that its atmosphere could be in the process of evaporating.

Astronomers find ‘Forbidden’ planet in ‘Neptunian Desert’ around its star

An exoplanet smaller than Neptune with its own atmosphere has been discovered in the Neptunian Desert around its star by an international collaboration of astronomers, with the University of Warwick taking a leading role.

The rogue planet was identified in the new research, led by Dr Richard West including Professor Peter Wheatley, Dr Daniel Bayliss and Dr James McCormac from the Astronomy and Astrophysics Group at the University of Warwick.

NGTS is situated at the European Southern Observatory’s Paranal Observatory in the heart of the Atacama Desert, Chile. It is a collaboration between UK Universities Warwick, Leicester, Cambridge, and Queen’s University Belfast, together with Observatoire de Genùve, DLR Berlin and Universidad de Chile.
