55 Cancri e, a planet about twice Earth's size with a carbon-rich atmosphere, likely from gas escaped from its molten rock surface. Previous findings hint at a carbon-dominated composition, possibly with a diamond core due to extreme conditions.
JWST data reveals a thick layer of carbon monoxide or dioxide around 55 Cancri e, mixed with molecules like water vapor, sulfur dioxide, and nitrogen. The planet's dayside temperature and atmospheric composition were measured using NIRCam and MIRI instruments.
