  • A microphotonic astrocomb is demonstrated via temporal dissipative Kerr solitons in photonic-chip-based silicon nitride microresonators with a precision of 25 cm s–1 (radial velocity equivalent), useful for Earth-like planet detection and cosmological research.

  • Cross-correlation analysis of high-resolution spectra obtained as the exoplanet KELT-9b transited its host star reveals neutral and singly ionized atomic iron and singly ionized atomic titanium in the exoplanet’s atmosphere.

  • The signatures of water, carbon monoxide, hydrogen cyanide, methane, ammonia and acetylene are observed in the transmission spectrum of the hot Jupiter HD 209458b, with abundance ratios suggesting a super-solar carbon-to-oxygen ratio.

  • The authors find that a nearby planetary system has two terrestrial planets that transit in front of their star (from our perspective). Transiting terrestrial planets are sought after, as they can be characterized in detail, including their atmospheres. Having two in the same system is very rare.

  • Data from the Kepler spacecraft and the HARPS-N ground-based spectrograph indicate that the extrasolar planet Kepler-78b has a mean density similar to that of Earth and imply that it is composed of rock and iron.

  • Kepler-107 b and c have the same radius but, contrary to expectations, the outermost Kepler-107 c is much denser. This difference cannot be explained by photoevaporation by stellar high-energy particle flux and it suggests that Kepler-107 c experienced a giant impact event.
