Newly discovered carbon monoxide-runaway gap can help identify habitable exoplanets

The search for habitable exoplanets involves looking for planets with similar conditions to the Earth, such as liquid water, a suitable temperature range and atmospheric conditions. One crucial factor is the planet’s position in the habitable zone, the region around a star where liquid water could potentially exist on the planet’s surface.
