The first successful detection of gases in the atmosphere of a super-Earth reveals the presence of hydrogen and helium, but no water vapor. The exotic exoplanet, 55 Cancri e, is over eight times the mass of Earth and has previously been dubbed the 'diamond planet' because models based on its mass and radius have led some astronomers to speculate that its interior is carbon-rich. Now researchers have been able to examine the atmosphere of 55 Cancri e, also known as 'Janssen', in unprecedented detail.
