A Stellar magnesium to silicon ratio in the atmosphere of an exoplanet: #Exoplanets and Their Host Stars: https://noirlab.edu/public/news/noirlab2609/ - new observations provide the first direct evidence that exoplanets inherit rocky-element ratios from their host stars.

A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2
The transit method is currently one of our best means for the detection of potentially habitable "Earth-like" exoplanets. In principle, given sufficiently high photometric precision, cool Earth-sized exoplanets orbiting Sun-like stars could be discovered via single transit detections; however, this has not previously been achieved. In this work, we report a 10-hour long single transit event which occurred on the $V=10.1$ K-dwarf HD 137010 during K2 Campaign 15 in 2017. The transit is comparativ…
